Opened the refrigerator door to be greeted by a buzzing sound and a light that flickers in time to the buzz. The unit is running, the light in the freezer works. and the fridge seems to be staying cold.
Removed the light… no difference.
Vaccuumed the coils, they were clogged with dust, but not too badly… no change.
The display in the refrigerator that shows freezer and fridge status are not lit.
I have a feeling that even though I can hear it running, it may not be cooling.
Rolled the fridge out and took the back off.
Attached to the side, down low in the back on the refer side is a small white plastic box.
Inside it there is a printed circuit board with two relays… one of the relays is what is buzzing.
We are experiencing the same symptoms. What is the solution?

what needs to be replaced. please help!
I would replace the electronic control board in the back where the noise is coming from AP4334000 I would spray all connectors with a non-residue contact cleaner first to make sure it’s not a bad connection causing this. If the freezer and fridg section temperatures are "normal" I would not suspect the fridg. control module is bad.
