WHISTLING NOISE DAY AND NIGHT IN FREEZER SECTION REFRIGERATOR GE MODEL GSS201BPDWW WHEN MOTOR IS WORKING

Replacing Evaporator fan motor and main control board on ge side by side. Video.

Same problem and think this unit is a piece of JUNK. In 5 years of service i have had to replace the Water shut off Valve twice, and the heater located on the bottom of the freezer which helps to keep the freezer defrosted. The fan has a whistling sound constantly, within 2 days of putting something in the freezer it is full of ice. Sorry pal, but as I said this model is a piece of junk.

is this a loud whistling, like a dying bird stuck in your freezer, or is this a lower pitched, sort of gentle whistling sound. If its the former, you likely have a faulty freezer fan motor. replace
if its the latter, sounds like you may have a issue with the door damper, which allows the air flow from the freezer into the refrigerator. However, assuming you dont have any cooling problems, you didnt mention if you do, it may simply be a normal occurance, as some makes and models open and close this damper door automatically, and when it is closed, can sometimes cause a low whistling noise

you have condisation on your condensor fan and it is vibrating. when you defrosted the unit you melted all the ice in the freezer. once the unit got cold again you had the same problem. it happens when you open the freezer door. the only way to fix it is to repalvce the fan and fan motor, as well as the main board. this is a costly repair unless it is under warranty.

Try removing the freezer light bulb completely.

Remove the freezer panel to access the fan motor. Look for any obstruction around the fan or blade. Ice, misplaced wire etc.
Check the fan blade. Sometimes they slip down the shaft too far.
If you find none of these issues, replace the fan motor.

the fan motor is probably going bad.its about a $50.00 part and its behind the back wall,grab the model number and go to an appliance parts store and order or pick one up.

Pull the cover off to the fan and compressor housing and clean it. Clean coiling as well. Most coils are located under the unit. They make an appliance brush to reach between the coils that can be purchased at an appliance store.

Mine was making a moaning, whistling noise coming from just above the ice maker. It happened when the fan speed changed. I learned on this site that the motherboard was probably defective.
Rather than go thru GE, we found a new one online for 66 bucks. I replaced it in about ten minutes and it's all fixed. Poor materials on the original, but this site was very helpful.

check the rear of the freezer you may find a build up of ice there if so you have a defrost problem chances are the heater is bad you can unplug ref and let thaw or you can tear into the rear (pretty easy) and defrost with hair dryer and look at theheater which is a glass tube usual only one at the bottom of the coils but some models have two one in the center you will most likely find them bad if they are not chrome looking then they are bad replace defrost thermostat also this is common rule.let me know what you find god luck
