Whistling noise True Freezer whistles when it runs. When it stops I hear the fan paddles slowing down, perhaps touching something??? Just acquired this freezer, it has less than 6 mos. usage on it. Like New otherwise. thanks. tlp

That'll be the door sealing itself. If it continues longer than a minute, then something might be wrong

There is an overheat klixon on the evaporator that stops the fan running until the coil gets below -11c This can take some time after startup. if the freezer runs more than an hour before the fan starting, check the klixon isn't faulty, and you have power to the fan. Also check the condenser grille is nice and clean as it will slow down the freezing process.

Hello sangpark003 - Often when the unit is making a whistling noise, it is because it is pulling air from the outside. Sometimes a poor door gasket could be causing the whistling. You may check if the door seal is bad; place a dollar bill between the body of the freezer and the door. Now close the door. The dollar bill should stay in place and pull out with a small amount of resistance. If the dollar bill falls out when placed between the gasket and cabinet double check to see if the door is being blocking by anything stopping it from closing. However, if issue persists, I would personally contact a professional to accurately diagnose the refrigerator to determine the root cause to reduce the risk of unnecessary parts or to confirm if it is a normal operation noise.

One of two things are probably happening. If you have a distorted, torn, or missing part of a gasket it may whistle when the air in the compartment suddenly shrinks inside the cabinet when the door is closed. Second possibility is that you have an equalizer tube that allows the air pressure to equalize when the door closed. It occurs to me that maybe the fan inside the freezer may have bearings that are in the process of failing and only complain when the fan motor begins to start up after the door has been closed. hope this helps. Good luck!

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.....

Behind the back panel you will find the freezer fan motor. unplug and take everything out. take the back panel off and find the fan. stick something in the blade like a bannana or whatever (no rags or paper towels though) just something to jam the blade (its plastic so dont break it) replug. remove whatever you put to jam the blade and if you hear the sound then you know for sure it is the fan. got to replace fan if you want the noise to stop
if it is not the fan let me know
hope this helped

we specialize in true freezer repair in illinois. Is compressor running or fan under unit? if not the thermostat may be bad.

check condenser fans, if defective or running slow change it

if condenser fan is running, suspect a compressor with internal mechanichal problems, it will run but i can't guarantee how long, maybe a couple of weeks or days. if it's an copelamic compressor, it's going bad.

Sounds like the freezer evapurator fan... they make noise on and off at times when bears are wore... Thats about the only thing that can make noise inthe area ur talking about.. if noise comes back listen where the freezer fan is.. is most liklly the problem
