I have a GE bottom freezer fridge that has been acting up for a few months. It started with an intermittant black out of the temperature display. A few weeks ago the lights went out all together and I lost the ability to control the temperature on the fridge/freeze. i assumed that it would stay at a default temp and that all was good.
On the weekend I had a power outage for 5 minutes at my house and that when I noticed the fridge/freezer was no longer cooling. Doing some research I am lead to believe that the main board is the culprit. The fridge makes no sounds what so ever anymore. Even when I plug it in I hear no relays clicking.
I have pulled the main board to inspect and I see on the board P/N#/Service number WR55X10416. Upon closer inspection I see four burn marks on the board on the rear of the curcuit board labeled "R6, R7, R8 & R12". One of the connectors to the board from what I believe to be a transistor mounted to a heat sink middle left on the board has also been completly severed from the burn.
From the research I have done, I want to see if any of you know why this has happened from my description. I am nervous buying a new board only to have it fry due to another problem with one of the other components that has caused this original circuit board to fail.
Please advise how to proceed and if there is anything else to check or troubleshoot before installing a new board?
