the freezer has been going on and totally off defrosting everything for over a week now. paid 50 dollars for a technician to look at it and said the compressor was out. if the compressor is out it wont be working at all. after he left .the next day it started working.
You will need a meter to check this out. Go to web site www.applianceguru.com/forum1/3075.html Locate the main motherboard in the back of fridg. pn wr55x10552 You can check compressor current, resistance of all the thermistors, etc
I fixed one of these boards, it had a bad solder joint on the back of the board.
They have had a lot of trouble with these boards and the part # given is for the re-designed board.
Make sure your evaporator fan and condensing fan motors are working well, then just order the new board.
