True Freezer Troubleshooting

The True freezer is one of those appliances that tends to go unappreciated until it's not freezing as it should. However, many things can go wrong with your True manufacturing freezer. As there are just as many simple fixes, you can try these fixes to get the unit back to keep in perfect condition. Have a look at these True freezer troubleshooting tips.

True Freezer Troubleshooting Guide

Find out the solutions for True Freezer not freezing, operates continuously, compressor problems, etc.

Freezer Running but Not Cold

We will see the basic operation of the cooling system in your True freezer before start the troubleshooting process.

The compressor releases a refrigerant to the condenser. The condenser coils transform the refrigerant from vapor to liquid while releasing heat which you feel blowing near the unit while it is in a cooling cycle. The cooler refrigerant flows into the evaporator through an expansion valve. From the evaporator, it absorbs heat from the freezer and cools the contents. After that, the refrigerant moves into a warm vapor, then returns to the compressor and repeats the cycle.

However, a disruption in the cooling cycle stops your freezer from cooling. So, you need to verify many factors that contribute to this issue. Before going into depth fixes, you have to fix some minor issues.

Thermostat

The temperature setting might be raised accidentally. If this is the case, simply adjust it.

Check for the defective thermostat as it does not send power to the refrigerant system.

To see if the thermostat is working properly, change the thermostat setting from lowest to the highest. If you notice a clicking sound, consider that there may not be a problem with the thermostat. Also, check the continuity of a thermostat using a multimeter. If it has no continuity, you need to replace the thermostat.

Defrost Timer

You should remove the freezer's plug while testing the defrost timer. Manually advance the defrost cycle by using a screwdriver. You need to turn the advancement screw clockwise until you hear the click sound. When you notice a click, this advances the cycle to the next mode. Wait for 30 minutes or one hour and inspect if it has resumed cooling. If the defrost timer is not advance, you have to replace it.

Evaporator Coils

Generally, the defrost heater melts any frost that accumulates on the evaporator coils. If this frost is faulty, frost will continue to accumulate on the evaporation coils. You can test the heater with a multimeter for continuity. If it doesn't have continuity, you will have to replace the heater. In addition, dirty condenser coils may cause to not transfer heat or cold efficiently.

Compressor

You can find the compressor at the bottom of the freezer. It emits a steady noise or humming sound that indicates that it is running. Clicking sound indicates that the compressor is overloaded or overrunning. If there is no clicking sound but your freezer is not cooling, then there may be an issue with the compressor or its components. So, you have to test each component and replace if it is defective. Also, check the start relay. If it smells burnt, it needs to be replaced.

Relay is Defective or Burned Out

You may have an improper size relay. Check and replace it if necessary.

The relay should be mounted at the correct angle.

Line voltage could be too high or too low.

Relay is being influenced by loose vibrating mounting. You have to remount it rigidly.

Incorrect run capacitor might be the reason behind this problem. So, you have to place the correct capacitor.

Suction Line Frosted or Sweating

Expansion valve passing excess refrigerant or is oversized - You need to readjust the valve or replace it with a smaller one.

Expansion valve stuck open - Clean the valve. Replace if necessary.

Check whether the evaporator fan is running or not.

True Freezer Stuck in Defrost Mode

If your freezer is stuck in the defrost cycle, you need to inspect the timer. A timer is the only component that controls defrost system. You can simply advance it out of defrosting.

Unplug your freezer from the outlet. Next, locate a small hole under the control panel and you will find a knob in the center of hole. Manually turn the knob in a clockwise direction. When you notice a loud click sound, it will be out of defrost and back in the normal cooling mode. Plug the unit back in and it should start operating.

Final Words

Hope this True  Freezer troubleshooting guide helps you more to get back your unit running effectively. However, the way you treat your freezer, it will treat you in return. So, you should follow the regular maintenance tips to eliminate basic and common True freezer problems.

Honeywell Water Heater Troubleshooting

Do you have problems with your Honeywell water heater? Quickly diagnose and repair your water heater with our comprehensive troubleshooting guide. The chances are a bad thermocouple has shut off the gas to the pilot light or an issue with the pilot light. This article will show you how to fix Honeywell electric and gas heater.  

Honeywell Water Heater Troubleshooting

You can observe a green LED indicator on the water heater gas control when your Honeywell water heater not working. The error codes on the LED status will indicate the issue by reporting a number of flashes.

l O flashes - Control off or Pilot out

l 1 flash - Normal operation

l 2 flashes - Thermopile voltage is low

l 4 flashes - Temperature exceeded

l 5 flashes - Sensor failure

l 7 flashes - Gas control valve failure

l 8 flashes - Power off failure

The thermopile generates electricity in the Honeywell water heater that is needed to power the gas control valve. It will take up to 90 seconds to get hot enough to power the gas control valve once the pilot is lit. When it happens, the status light will blink once every 3 seconds which indicates normal operation. If the light blinks more than once every three seconds, you need to refer to the status light code list or label on the gas control valve.

Try lighting the pilot by following the lighting instructions given in the manual or on the heater and visually confirm the pilot can be lit. Next, set the gas control knob to "Pilot". Hold the control knob in while clicking the igniter button and looking through the inside water heater to the left. In order to see the pilot, you may have to dim the room lights.

If there is air in the gas line, it may take up to 90 seconds before the pilot lights and the status light begins to blink. Even after 90 seconds also, if the status light won't start blink, you have to release the control knob and turn off the gas valve.

You should wait ten minutes before attempting to relight the pilot. On newly installed water heaters, it may take 2 to 3 lighting attempts before the pilot lights and status light starts blinking.

Two flashes and three-second pause - Weak pilot signal is detected.

The system will reset when the pilot flame is sufficient. Thermopile failure, unstable pilot, blocked/ restricted pilot tube, or opened resettable thermal switch might be caused this problem. You can check the troubleshooting tips in the service manual.

Three flashes and three-second pause - Insufficient water heating.

The temperature sensor could be out of calibration. Check and recalibrate it.

Four flashes and three-second pause - Excessive tank temperature.

Check for faulty gas control and verify if the temperature sensor is out of calibration.

Final Words

We hope our guide on Honeywell water heater status light codes and Honeywell water heater troubleshooting was helpful and it was able to get back your unit running. When you need to go through Honeywell water heater thermostat replacement or controller replacement, it's better to call a professional. Still, if your Honeywell water heater not working, refer to the manual and fix the issue.

How Does A BASO Switch Work?

Do you want to know how does a BASO pilot safety switch work? You have reached the right place to get the details on BASO switch. Here, we have provided the information regarding the BASO pilot switch working process, installation, importance, etc. So, have a look at this blog post to get the details on Baso pilot safety switch.

How Does a BASO Pilot Safety Switch Work?

BASO pilot switches are used on all gas-fired and standing pilot equipment that requires the main burner to shut off when the pilot is extinguished. Typical applications include domestic central heating and commercial space heating appliances as well as industrial processing equipment.

These pilot switches monitor the pilot flame through the use of a thermocouple. In 100% shutoff model applications, if the pilot flame is extinguished, then the switch will be interrupted gas flow to the pilot burner as well as the main burner and caused for shutting down the appliance.

In non- 100% shutoff model applications, the switch will interrupt gas flow to the main burner only when the pilot flame is extinguished. Pilot gas will continue to flow until the pilot gas is manually shut off. 

L61 BASO Pilot Switch

The L61 is an automatic resetting device that opens the main gas valve electrical circuit if the pilot flame is extinguished. Lighting or relighting the pilot burner causes the device to close the electrical circuit of the main gas valve and allowing the appliance's main burner to operate.

This switch receives its energy from a heated thermocouple. Because BASO L61 has features like automatic resetting and minor pilot flame fluctuations which may cause the device to drop out and will not shut down the unit permanently. Moreover, it will automatically close and restore service upon resumption of a normal pilot flame. L61 models are available with Single Pole Double Throw switching actions when an additional switching function like a need of signal light.

BASO Safety Shutoff Device Installation

Before starting the installation process, you should turn off the power to the appliance.

Shut off the gas at the main manual shutoff valve adjacent to the appliance.

Remove the device cover by loosening the screws at the side.

Now, mount the switch in any convenient position using the mounting holes provided.

Push the circuit wires through the conduit opening on the bottom of the device. Strip the ends of the wires just enough to put the bare wire under the terminated screws and attach them to the two-wire terminals.

Replace the cover. Do not loosen the grass hex nut.

Attach the thermocouple securely to the pilot burner. And, screw the terminal end to the BASO power unit terminal on the pilot switch. Ensure that this connection is secure. Tighten the thermocouple lead nut finger tight that is finger tight plus a maximum of 1/8 turn. You should not overtighten it.

Check the Adjustments after Completion of BASO Switch Installation

Make sure all components are functioning properly by performing the following tests.

Test all joints and connections for leaks with a soap solution.

Set the thermostat to the lowest setting.

Close the main manual shutoff valve and pilot valve and wait at least 5 minutes for unburned gas to escape from the appliance.

Reopen the pilot valve and ignite pilot gas and wait for 30 to 45 seconds.

Push down the red indicator and aluminum reset button to its full limit of travel and release. If the red indicator remains depressed, the unit is operative. If the red button doesn't stay depressed, wait for another 30 seconds and try again. If the second attempt also not successful, check that the thermocouple output meets the desired value.

Open the manual main shutoff valve after the red indicator button remains in the depressed position. The main burner will ignite from the pilot burner when the thermostat calls for heat.

Disconnect the thermocouple from the device. The main shutoff valve should close immediately. If it is not closing, you have to check for wiring errors. Once, you have decided there are no wiring errors, reconnect the thermocouple to the pilot switch.

Re-light the pilot and observe at least 3 complete operating cycles to make sure that all components are functioning correctly.

Reset the thermostat to a normal temperature setting before leaving the installation.

Conclusion

Hope the information updated above on the BASO pilot switch useful for you. If you know the basic working process, installation, and testing, then you can easily fix the problems yourself when it has trouble.

Blodgett Oven Installation

Blodgett ovens represent the latest advanced technology in energy efficiency, reliability, and ease of operation. In these ovens, heat is normally lost and is recirculated within the cooking chamber before being vented from the oven that resulting in substantial reductions in energy consumption and enhanced oven performance. However, in this blog, we have updated the process for Blodgett oven installation. Take a look at this complete post.

Blodgett Oven Installation Procedure

Cooking in a Blodgett convection oven is different from cooking in a conventional deck or range oven since heated air is constantly recirculated over the product by a fan in an enclosed chamber. The moving air continually strips away the layer of cool air surrounding the product and quickly allowing the heat to penetrate. The result is a high-quality product, cooking at a lower temperature in a shorter amount of time. Now, check out how to install a Blodgett convection oven.

Oven Location

If you placed the oven at the proper level. Then, it will give the long-term operator convenience and satisfactory performance.

You need to maintain the below clearances between the oven and combustible or non-combustible construction.

Oven body right side - 1 inch.

Body left side - 1 inch.

Oven body back - 7.5 inches

Body bottom - 4.5 inches

Make sure there will be an adequate air supply to the oven to provide a sufficient flow of combustion and ventilation air.

The area where you have to place the oven that should be free of drafts.

Try to keep the area free as well as clear of all combustibles such as cardboard, paper, solvents, and flammable liquids.

Don't place the unit on a curb base or seal to a wall. Because this will restrict the flow of air and prevent ventilation. An excessive ambient temperature on the right side of the oven caused to tripping of the blower motor's thermal overload device. So, you should correct this condition to avoid permanent damage to the unit.

Leg Attachment

Need to push your oven onto a lift with the bottom of the unit down.

Align the threaded stud in each leg with the nut located inside each bottom corner of the oven's frame. Now, turn the legs clockwise and tighten to the nearest full turn.

You have to align the two-leg plate holes in each leg with those in the oven bottom. Fix the leg with two 1/2" bolts.

Now, level the Blodgett oven by screwing the adjustable leg feet in or out as necessary.

Blodgett Oven Assembly

Secure the short legs to the bottom sections.

Place the upper section in position on top of the lower oven.

You have to place the clips over the edge of your oven frames.

Tighten the clips by bolting together with 3/8" bolts and nuts provided.

Now, attach the flue connector.

Gas Host Restraint

If the Blodgett oven is mounted on casters, you should use a commercial flexible connector with a min of 1.9 cm inside diameter along with a quick-connect device.

You will get this restraint along with the oven that is used to limit the oven's movement. So, no strain is placed upon the flexible connector. Installation of the restraint with a fully stretched connector is easy and quick connect.

The restraint should be attached without damaging the building. Don't use the electrical conduit or gas piping for the attachment of the restraint's permanent end.

Mount the bracket to the leg bolt just below the gas inlet. And, attach the clip-on restraining cable to the mounting bracket.

Final Words

That’s all about Blodgett oven installation. However, the installation should be done by a professional or expert to avoid dangerous problems. If you need further more assistance, you can refer to your Blodgett oven manual. Installation instructions may vary from model to model.

 

ASCO Red Hat Solenoid Valve - How to Select, Installation & Maintenance

 ASCO Red Hat Solenoid Valves are used for the control of fluids. These valves are available in various models, each designed to meet specific requirements. Are you new to use ASCO Red Hat Solenoid Valve? We are here to help you by providing useful information regarding ASCO Red Hat Valve. If you need to know how to select ASCO Red Hat and Red Hat II Solenoid Valves, installation and troubleshooting, read this entire post, it may help you.

Two Way Valves

Two-way valves have one inlet and outlet pipe connection. These will help you for normally open and closed operations. Normally opened valves are open when the coil is de-energized and close when the coil is energized. Normally closed valves are closed when the valve is de-energized and open when the proper voltage is applied to the coil.

Three Way Valves

Three way valves are designed with three pipe connections and two orifices which are alternatively opened or closed. These ASCO valves are available for normally closed, open or with universal construction that is used as normally closed or normally open. Three way ASCO Red Hat Solenoid valves are mainly used as pilots for larger control valves to actuate single-acting cylinders or to divert the flow of fluids.

Four Way Valves

These valves have four pipe connections. One for exhaust, one for pressure and two for operating double-acting cylinders. Four way valves are used to pilot larger control valves.

Manual Reset Valves

Manual reset valves will be closed or opened manually and then revert to their original position when they are energized or de-energized. These are used for preventing the inadvertent startup of critical systems.

After determining the basic ASCO solenoid valve type, while selecting, you should consider pipe size including flow rate, orifice size, pressure rating, ambient & fluid temperatures, medium to be controlled, type of solenoid enclosure, voltage, cycling rate and required life rating. Each factor's importance needed to be determined by the application itself.

ASCO Red Hat Valve Installation and Maintenance

To increase the valve life, you should install and maintain it properly. However, you need to read and follow the instructions given on the red hat and red hat II valve for each model.

Installation

You must check the nameplate data for voltage, pressure, etc. to ensure compatibility with your system conditions. Moreover, you have to know that the solenoid enclosure type with your operating conditions.

Some red hat valves will operate in any mounting position, while others have to be mounted in a certain way to operate correctly. However, it's better to install these valves with the solenoid in a vertical upright position. If you install the valve in a vertical upright position, there will be less chance of foreign matter accumulation in the core tube area. You need to install the filter or strainer as close as possible to the red hat valve inlet.

The wiring should have complied with the local codes and the Canadian Electrical Code. Make sure you don't pull out from the coil. If you are not using a flexible conduit for transition into the valve, the supply conduit should support properly to reduce stress on the solenoid assembly.

Final Words

Hope you got an idea about ASCO Red Hat Solenoid Valve and your job might be done easier to select the appropriate ASCO Red Hat Valve and installing. For further more information on the ASCO Red Hat II Solenoid Valve, you can refer to the valve manual. Moreover, PartsAPS offers ASCO solenoid valves so you can buy here if you need them. 

Star Deep Fryer Troubleshooting

Star Manufacturing deep fryers are important in most commercial kitchens. And, it's common to experience malfunction once in a while. That's why it is important to know some of the most common Star deep fryer problems and their fixes. It's easy to fix the basic issues that come with your fryer. Let's start reading a few problems and tips to solve the problems of Star Mfg deep fryer.

Star Deep Fryer Troubleshooting Guide

Find the simple solutions to fix the basic Star fryer problems

Deep Fryer Pilot Won’t Light/ Pilot Light is Out

If the fryer's deep pilot light is out, you can consider that your unit is completely out of condition. The oil does not heat up to its right temperature without a pilot light. There are many reasons behind the deep fryer pilot light out. But, mainly due to the main gas supply valve issue, this problem will occur.

Check the supply line for any blockages, this is the best choice to confirm that problem is with the gas supply valve. While inspecting, if you observe that the supply valve is open and clog-free, then you have to replace the thermopile. The thermopile works as a main heating element in the fryer that converts thermal heat into electric energy. Therefore, signaling the pilot light to ignite the flame. It is fairly simple to replace the thermopile. If you are unable to replace it, contact a professional.

Thermostat Failure

If you are seeing temperature fluctuations when using the Star Mfg deep fryer, it might because of a defective thermostat. When the temperature is off, it's likely that the fryer will continue to burn or undercook your fried and correct recipes until the problem is fixed.

If you notice any problems with the heating capabilities of oil, you should place a probe-style thermometer inside the oil for testing its average temperature. When you are testing, the temperature must be consistent. If the oil temperature is inconsistent while testing, you will need to re-calibrate/ rewire or replace the internal thermostat. Also, check the wires behind the fryer thermostat are disconnected. If so, connect them properly.

Hi-Limit Switch is Not Working

Sometimes, you may get problems with hi-limit thermostats. Hi-Limit thermostats are placed inside the fry tank near the burners. Like an internal thermostat, the hi-limit switch caused to not heat the frying oil to its arranged temperature. If this switch is a reason for your deep fryer's inconsistent oil temperature, replace it to resolve the issue. If you don't know how to replace the hi-limit switch, you can call a service technician.

Poor Oil Circulation

If the fryer oil filter fails, the flow of oil will become weak and makes it impossible to complete the deep fry food successfully. You will hear and see the oil circulation sound when your Star deep fryer is turned on if it's filtration pump is operating properly. If your oil flow becomes weak, you can simply change the oil filter. Sometimes, this will work effectively. But, in some situations, the O-rings could not fully tight & secure. Damaged O-rings often interfere with a stable air pressure balance. So, you should fix them carefully even it is easier. Otherwise, need a professional technician to get complete functionality.

Conclusion

That’s all about a few common problems of your Star manufacturing deep fryer issues and their solutions.
