Product review (5 stars): I had a technician come out and he determined that the board was probably bad because the fan worked
The freezer section of my GE profile fridge wasn't maintaining temperature.  Sometimes ice cream was melted, other times it was hard as a rock.  I had a technician come out and he determined that the board was probably bad because the fan worked, but it wasn't always successful at signaling the fan to run.  He gave me a work order of what it would cost to fix, almost $400, $185 of which is what GE was charging for a new board.  I purchased this board which matched the item from the work order and installed it in about 10 minutes.  The freezer works perfectly now.  The only advice about the install is to take a picture of the existing board connections or mark them.  I was surprised at how many there were.
