The freezer area makes constant noises groaning whne door is closed, stops when door is opened


I'm going to say it's a bad bearing in the fan. It shuts off when the door is opened so as to waste as little coldness as possible.

Amana Bottom Freezer door when shut starts a noise


The light is switched on and off by a small lever which is pushed when closing or opening the door. This operates a microswitch. It would not make any grinding noise. Grinding noise can come from the fanmotor which would also stop when the fridge door is open.

Evaporator Fan Motor noise is excessive for this refrigerator. GE Profile CustomStyle Model PTI22SFMARBS Serial# SF900146V


Despite my urge to vent about GE refrigerators, I'll keep this short.

If you have a constant squealing noise from the evaporator fan in the freezer, there's a good chance the fan just has failing bearings, and replacing the evaporator fan might solve the problem.

But if the noise is intermittent; quiet sometimes but sometimes buzzing loudly, then my bet is there's nothing wrong with your evaporator fan. It's a problem with the design of GE fridges: They don't defrost completely. So ice builds up on the back freezer wall, etc., and on and around the evaporator fan. That's not a problem when the fan is in "low speed mode". But open the door, get the fridge warm, and the fan kicks into "high speed mode". That's when the noise will start, as the fan blades and assembly warps under speed to hit ice and start vibrating.

Acid test is this: While the noise is occurring, turn the fridge temp (not freezer) control up as high as you can without turning off the fridge. That will make the fan shift into low speed. If the noise stops, you got ice on the fan, my friend.

In that case, unplug the fridge, and get a hair dryer and blow warm air into and onto the evaporator fan area. Maybe gently whack the fan area with your hand a bit, to knock the ice off. Once you get all the ice off, turn it back on. If it runs on high, without any noise, the problem is fixed ... until the next set of high humidity days. I plan to post a video about this, once I get it edited to remove the expletives. ;-)

GE will sell you a "moisture kit" for $340, which may fix the problem, but only if your fridge is out of warranty.

If your fridge is still under warranty, GE will tell you there's nothing wrong and that maybe you just need ear plugs.
