Good Morning,
I’ve read previous posts on this symptom but just wanted to be sure it was the main board before I ordered anything. I cleaned the coils/fan area. Display is working, cooling it fine. There is a knocking/rapping coming from the main board area of the refrigerator. The knocking can happen once or up to 7 or 8 times in a row, then nothing for minutes to hours. Sounds like it’s coming from behind the board. The knocking sounds too loud to be coming from the relays on the board. Any thoughts?
UPDATE: I’ve listened to the inside of the fridge and it seems to be coming from the back panel (damper?) Could the damper be failing?
If can clarify any information, please let me know.
David
