Hi. I have a GE Profile French Door, Bottom Freezer unit. It stopped cooling earlier this week, and a service tech came and diagnosed that the evap fan motor needed replacement (tiny white one with skinny 3" fan shaft). It would run, but not if it stopped in the wrong position (one open winding, maybe?).
My wife was here today when another tech came to install the replacement motor, and afterward reported that the fridge was completely out of order.
He suggested replacing the mainboard. I am skeptical, and concerned that if it is the board, then maybe something was done that fried the board. Replacing with another could render it useless too, maybe? I am technically inclined, but have no service manual... what should I do next to determine my current issue? Thanks in advance, this seems a great forum. :)
The first thing that you will want to check where the power cord comes into the unit at the control board and make sure that there is 120 vac to it. If there is then the issue will most likely be in the control board. Could be the unit may have went into a defrost mode and stuck. This would be a control board issue.
This morning I got up and my fridge was 52 (set on 37) and my freezer was -15 (set in 0). I started looking into it and there was an inch of ice on my freezer floor. I got behind the fridge and I could see the compressor and fan running fine. Would this be a bad mother board.
There is a damper that is located at the back of the refrigerator compartment that needs to be checked to make sure that it is opening and is not damaged. If the damper is not opening it will cause the issue that you are having with the unit. For the ice that is on the floor of the freezer, this would be a issue of a clogged drain which is located under the evaporator behind the wall in the freezer. Clean out all the ice and flush with hot water.
