There is a switch above the door; check you have power from it when closed, then check the evaporator is cold enough as there is a thermistor that stops the fan until it is beginning to freeze. Lastly check the fan blade isn't stuck and the motor is ok.

SOURCE: Freezer Not Fan not running!

Most all commercial freezers have some sort of fan delay/ defrost termination device. Commonly called a "Klixon" (pronounced clicks-on). It is a device that is attached to the evap. It's function is to terminate the defrost cycle when the evap reaches a certain temp, say about 50 degrees or so, to ensure there is no build up of frost/ ice on the evap. It then allows the compressor to run, and cool the evap down to a reasonable temp., say about 20 degrees, and then let the evap fan come on. It prevents overloading the compressor during a high temp condition, and it also prevents circulating warm air left from the defrost cycle. I believe this device is most likely your problem. With no air circulating, the box will no cool down.. I have seen them burn and/or slhort internally. They can come apart. too. I would look here for that problem. the True manufacturing website does not give alot of info on this piece of equipment, such as a wiring diagram but manuals are available.
Check this out and let me know how it comes out.

SOURCE: We have a true T49F freezer and the evaporator

Freezers have a sensor that is referred to as a "Fan Delay/Defrost Terminator". It senses the temp during the defrost cycle. Usually, when the evap temp reaches about 50 degrees, there should not be any frost or ice on it. This device terminates the defrost cycle. It also keeps the fans off so warm air is not circulated. When the evap gets to about 20 degress or so, the sensor switches on the evap fans. If the fans are not coming on, either the sensor is bad or the evap is not reaching the proper temp to cause the sensor to turn on the fans.

Hope is helps to clear up some things and point you in a direction as to what might be going on.

SOURCE: true upright freezer. coil fan not running.

Let it run. Coil temperature has to be low enough for the fan delay switch to close.

The fan does not run on my woods freezer.


just b/c the fan is not running does not always indicate a bad fan motor. there is a capacitor and relays and switches that can go bad, my guess would be the capacitor. you need an electrician to verify though.

Fan not working


Generally I would check for power at the fan wiring because there are several components that can keep it from running. If the fan does have power change the motor. But if it doesn't is the coil frosted and cold enough to let the fan thermostat switch close?
Is the door switch good? Hope this helps good luck.

Daewoo FRN-U20IA top of freezer compartment won't freeze


It was the fan at the top of the freezer that had stopped working after 3 years, therefore the freezing air wasn't getting to the top of the freezer. From the inside, unscrew light unit and unclip, pop out two circular discs at top and unscrew one screw. Unscrew 2 more screws and prise the back panel off. (Arrows mark the clips). Pull off fan, take out motor, replace (keeping rubber bits) and push back fan with a bit of nail varnish on spindle. Put everything back together. Turn on, depress door light switch and after 30 seconds fan should rotate. You can buy a fan on eBay or from www.4daewoo.co.uk for about 40 pounds.

My freezer gets cold on the bottom but does not freeze anything. I never hear the fan come on. I replaced the thermostate but still the same. What part should I try next. I have model FFU14FC4CW1


Hello,

If the compressor comes on the thermostat is good, what you need to check is for power to the fan in the freezer, if power present at fan but it doesn't run the fan motor is bad.

What causes my true 19 to be so noisy? is there anyway to quiet it down?


Hello,

A noisy chest freezer can be more than aggravating, it can also be a sign that something may be wrong with the appliance. With a little investigation, you will be able to find the cause for the noise so that you can determine how to rectify it.

Self-defrosting
If you chest freezer is a self-defrosting variety, you will find that it has a fan on one of the inside walls that enables this process to take place. Open the door and check whether this makes the sound worse; if this is the case, the problem is likely to lie with the fan. Ensure that it is not blocked by any food items or ice and is running properly. Clear away any items that are blocking it and tighten any loose fasteners. The motor that runs the fan can also cause a noise if it is old or defective and is struggling to continue running, if this is the case, the motor will need to be replaced.

Door Seal
Examine the door seal of the chest freezer to ensure that it is intact and has no defects. If there is a problem with the seal, it can prevent the door from closing properly which will force the freezer to work harder as it will also be cooling the air around the freezer. Replace the door seal and ensure that the door is able to close properly to see if this reduces the noise.

Element
The wire element that is either located on the rear or the base of your chest freezer. The element can often become noisy after getting covered in dust and debris. Rectify this by switching off the power supply before vacuuming the element. Carefully use a cloth to clean any other surrounding components that are affected by stubborn grime.

Ice Build Up
Where your chest freezer is unable to regulate itself, you may find that it can suffer a buildup of ice. When the ice become sufficiently thick, it will stop the freezer from being effective and will force the motor to work harder in order for it to keep working. Prevent this problem by defrosting your freezer on a regular basis or whenever it is required.

Condenser Fan
The condenser fan is likely to be located at the rear of the freezer and can become noisy if it is defective or covered in dirt. After switching off the power supply, use a cloth to clean the blades of the condenser fan if you find that the noise is coming from this component.

Compressor
The compressor is the black box that you will find on the base or rear of your freezer and is where the normal noise of the running the freezer comes from. The pipes and wires necessary for the freezer to work stem from this box and can become noisy if there is a problem, which is more likely with an older appliance. A defective compressor cannot be repaired so it will need to be replaced.

Hope this will help in solving the problem.....

Imperial commercial upright. Top shelf is icing and frezzing bottom is not freezing.


Hi,

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster than the fridge can cool it, which will thaw your food.

I hope this helps........

Good luck.

The fan on my true t 23f does not run. i check it is not getting power is there a fuzz or capacitor for this thanks


Are you talking about the fan inside the freezer? If yes, check the following items. The door has a switch that turns the lights off when the door closes, it also turns the fan off when you open the door. If it isn't working right the fan won't come on. There is also a round temperature senser on the coil inside the freezer called a "clickson" that keeps the fan from coming on until the coils are below 20 degrees, it may be bad. If you are low on freon, your coils may not be getting cold enough to trip the clickson. Feel of the small copper line going from the compressor to the coils on the outside of the freezer. It should be almost hot enough to burn your skin if you have enough freon. One other thing to check is the defrost timer. It is a box about 4 inches wide and 8 inches tall with a door on the front of it. Check the connections inside to be sure you are getting power through to the fan. Let me know how it turns out.
