Groaning noise on GE side by side refrigerator
Hello Michael,
Thanks for your question, I hope I can help some. My answer is long winded but full of good info.
The noise could be as the GE guy said refrigerant (gas) noise. If it is refrigerant noise it happens as the liquid refrigerant comes out of the tiny capillary tube and enters the evaporator (cooling) coil in the freezer. Along with the liquid coming through the capillary tube there often are gas pockets. The flow of the liquid and gas pockets into the evaporator coil cause strange sounds. If the noise you are hearing is this refrigerant noise, you should only hear the noise while the compressor is running and then only for a short time (1 to 2 minutes) after the compressor shuts off.
If the noise continues after that I do not think it is a refrigerant noise.
There are times when the compressor will not be running but the fan in the freezer will be running on this model. This is normal and working properly but if the noise is present when the freezer fan is running and the noise stops when the freezer fan stops, the likely cause will be the main board located in a square panel on the rear of the refrigerator above the compressor compartment. I know that sounds crazy but the main board can cause the freezer fan motor to make some really strange noises. Eventually the board will probably fail.
One other test would be for you to listen for the compressor to turn off, then if the noise is present after the compressor turns off, you would next unplug the refrigerator from the receptacle. If the noise continues with the refrigerator unplugged it must be refrigerant noise. If it stops, I am betting on a bad main board.
I tried to locate for you information on a material that Whirlpool and Frigidaire as well as some others use as a noise deaden-er that they wrap around where the capillary tube enters the evaporator. I was not successful in locating anything. I am sorry I could not find it.
