Had the exact same problem a while ago, and Maytag/Whirlpool said at the time that the needed part (the back control board) was back order. However, I found and used the online instructions for replacing the damaged capacitors on the board that seemed to solve the issue for many users, including some on this board. I put the board back in with the new capacitors and bingo: It worked!
... for about 10 hours. At 6 am the next day, the exact same problem reappeared. I unplugged it (my version of this problem is the complete one where the fridge no longer cools) and checked the control board. Most of it was really hot! I waited for it to cool down and plugged the fridge back, but no change. I was sure the problem was fixed but now I'm back to square one!
Anyone knows what could be done? I'm really not enthusiastic about ordering a new 300$ control board which MIGHT work, especially since the capacitor replacement fix didn't work, which might indicate another problem with the fridge. The Maytag/Whirlpool customer service isn't exactly helpful, although I will call them back and try to see what can be done.
Anyone tried to change de capacitors with no success and found another solution?
