I have a kenmore Trio that I've had 5 years. I've had 2 compressers and 1 new fan. Now it hums. Almost like faint music. Any suggestions?

It's probablly caused by air leakage through the ice room fan electrical connection inside the freezer. Behind the back wall inside the freezer, the icd fan is the fan that blows air up to the in-door icemaker. The plug on that, into a molded plug on the back of the feezer compartment, is a red plastic part with three wires in it. Try filling in around the wires and the red plastic with a bit of silicone. (if you replace the ice room fan, the new plug comes with a rubber filler which seals this spot). (PS. Next time, avoid Sears)

check the over-load/contactor on the side of the compressor,remove it and shake it if it rattles,replace it

if you need to assist the evaporator fan motor you need to replace. this should fix your problem.

Loud hum could also be from the air circulating fan in the freezer compartment.

it should not be the compressor as the bottom is only not cooling.

It is the compressor that has failed. The hum is it trying to start and the following click is the overload protector opening. What is the temperature where the refrigerator is located? Allow the compressor to cool down before trying to restart it. If it still does not restart after it has cooled off it is done.

you have a defrost proble you will need to acess the timer and advance it to defrost post the model number so i can direct you most likely your heater is out in the evaprator

I'll bet the freezer is not as cold as it was. Fully defrost the unit by leaving it unplugged for about 2 days. Check all gaskets. Clean the condenser coils under the unit. Restart. You have too much condensate in the box...either uncovered food or windowshopping or somebody didn't shut the door properly.

Did you ever get the problem fixed with the compressor noise

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.
