Product review (5 stars): Fridge hummed. It came and went every few minutes.
Amana AFI 2538 French door refrigerator.
OEM part#W10128791 for relay. OEM part# T08-36 for capacitor.

Replacement capacitor was larger than original, and  the replacement relay was white, not black like the original. But both fit exactly.

My refrigerator home to very softly for about 3 weeks. Then it got more regular and louder in the humming came more often. In the beginning it would only come once every 30 minutes or so softly. When I replaced his overload relays and starter capacitor running capacitor it had begun humming every few minutes constantly. The refrigerator with no longer cut off the last couple days it ran constantly. I happened to read about this problem online and this was the part they suggested changing.

After pulling refrigerator out and changing this part I let it sit for about 15 minutes before plugging it back in. It started up quietly and is now running perfectly. If you have this problem I suggest buying this part.

From what I read if you do not change the sport eventually the compressor will burn up and refrigerator will go out.
