I'm getting a "knocking'freezer noise coming from my AMANA bottom freezer. It sounds like someone is trying to get outm

Do you see any ice buildup on the back wall of the freezer or behind it?

the ptc overload relay on the compressor is bad and needs replacing unplug it off the compressor body and get an exact replacement for your model

Hi,

Here is a tip that I wrote about refrigerators and the fan noise that they develop sometimes...

Refrigerator Fan Noise

heatman101

The noise is likely the defrost heater coming on. This melts the ice on the evaporator coil. The melting ice is the noise you hear and maybe the panel flexing from the heat of the heater. This is normal.

This will be a loose mount on the electric motor (tighten)

hi doug,
with the amana of that age there are several weird noises, be glad you have only one. that aside
ill tell you all of em...
a clear pop..... usually after defrost its the compressor starting cold as they say.
a knock ( very much like you should answer the door) is the plastic liner popping back into place in the freezer, after defrost.
Then ther is the knock of the water solonoid, but that would be more than once a day.
you might be able to remedy these, by changing the box postion a bit,,, i know sound stupid but i was the old lonely for 15 years and this one was always tough to diagnos it never happened whiles the service guy is there.... so i bought one....

It could be unequal tightening of the mounting of the compressor. Also check the belt for uneven thickmess...........sodeep

Sounds like the overload/relay is going out . If the noise is a " click " , replace the o/relay after checking the 3 terminals on compressor for continuity and each terminal to ground ( copper tubing ) .

im sorry to tell you, but the sound is probobly normal.
fridges these days make some weird noises.
they started making noises when they changed the gas to R34a.
you may be able to get a noise ruduction kit for your model. they are not too fun to install

sounds like the compressor vibration dampers are wearing out. the dampers are the rubber washers that seperate the compressor from the chassis of the fridge. when they start to deteriorate, and the compressor kicks on, it will bounce against something in the chassis, causing a knocking noise.
