Compressor intermittently starts, loud humming when it doesn't
My frig has been making a loud buzzing, humming sound when it tries to start the compressor. I had a service person in and they initially replaced the (compressor relay) and the thermostat. The new relay did not work at all so he put the old one back and they did not charge me for that visit. The head technician said on the phone he did not know what the problem was and told me my compressor was probably going and there was nothing he could do. My frig is 4 years old. A couple of weeks later the noise and frequency of the (starter, relay?) was getting much worse and the compressor was coming on less and less. The frig was failing and the freezer was no longer cooling. I lost a lot of food and assumed it was just broken. I went to buy a new frig and finally shut this one off. I the day before the delivery of the new frig turned the old one back on and for 2 days it has been cooling well. The noise is much less frequent but there are times when it still tries to start the compressor and fails. But it is cooling, so I don't think it is the compressor and would really rather fix this one instead of buying a new one. I am afraid the problem will resurface quickly and would like some help as to what may be the problem. Additionally, I am capable of replacing parts myself if I know which ones to buy.

Now then is it the compressor that is making the loud humming noise and does it repeat it several times a hour/day ??
The buzzing humming noise is coming from the compressor due to the start relay being burnt and the relay should be replaced. The relay clips onto the compressor and is held in place by a wire retainer under a plastic cover on the side of the compressor.
The part number for that relay is 8201786 it could be purchased at your local appliance parts store or online at; searspartsdirect.com apdepot.com repairclinic.com apwagner.com partselect.com

You have one of two problems going on. Your fan is spinning at hitting the sides. Or your compressor is shot which seems to be more the problem and even though it is cold the humming sound is a warning for you that the compressor is shot and it is more affordable to replace the fridge then the compressor. Sometimes compressor can cost more then the fridge.
if both sides are hot it sounds as if the compressor isnt running. pull the refig away from the wall and remove the cardboard cover the compressor is the black bowling ball loking thing that you see. fell to see if it is running should have vibration and making a humming sound. if its not running listen for 3-5 minutes to see if you are hearing an intermittent humming and clicking noise. this would indicate a bad start relay for the compressor. if the compressor is running then you mostlikely have a freon problem which will require a qualified technician to repair. good luck and thanks for using fixya Peyton..
The grommet simply holds the start relay in place. Unless it is torn, you won't need it. Likely the start relay. The buzzing is possibly the relay contacts on the start relay burning if the problem occurs when the compressor starts...although it could be the compressor making noise as well. You might try to "hear it out". The start relay gives a boost to the compressor by adding in another winding inside to 'kick' the compressor.
If all you hear is the buzz, you might just wait a bit to see what fails!
It sounds like the ice maker. If you don't have the water hooked up, and the ice sensor bar is in the down position, the ice maker assembly will attempt to make ice continuously. Solution is easy: raise the ice sensor bar until it clicks in the up position. It will lock in this position, and the ice maker will not cycle anymore.
most likely the compressor relay is the clicking noise but i think the problem is most likely the compressor is starting to go bad and is lcoking up. if the refig is under 5 yrs old it is most likely still in warranty by amana
It sounds like the condensor fan motor is seizing up. This is the fan that cools the compressor down. Does the outside of the fridge feel excessively hot to touch? Can you feel air being circulated under the fridge or behind the fridge? It could also be a faulty defrost timer. Try to identify where the buzzing is coming from and if it is the condensor fan you can put a normal standing fan behind the fridge, blowing onto the compressor untill the repairman can get to you.
