Freezer not cooling or excessive frost buildup? The defrost control board manages the defrost cycle. Moderately difficult repair with video guidance.
The refrigerator was given to me and hasn't defrosted since it was new. I found the defrost timer had a burnt spot on the circuit board. After installing a new timer, the refrigerator would trip the circuit breaker in my house when it entered defrost mode. I found that the pink wire running from the control board all the way to the thermostat was shorted somewhere between the two parts, inside the refrigerator. I ran a new "pink" wire and all is good.

Freezer icing up or fridge warm while freezer works? The defrost timer controls defrost cycles. DIY-friendly fix in about 1 hour, saves $150+ on service.
I had had the same problem 4 or 5 years ago and spent close to $200 to repair it. I did have the slip from that repair with part #'s so I went ahead and ordered a defrost timer and thermostat.

Ordered and replaced timer. (15 minutes) Problem fixed!!! Saved purchasing a new fridge at big bucks. We live over 40 miles from a service center so the cost of having a tech come out is astronomical. Thanks!!! Read more
Fridge not cooling or running constantly? A faulty defrost timer causes frost buildup and temperature swings. Most DIYers replace it in 15 minutes.
At first, I suspected the evaporator fan motor was going bad, but when I went in to check it out, I found the evaporator coils totally frozen up; the fan was cavitating. I defrosted the coils completely and checked everything out. By process of elimination the Defrost timer had to be the culprit. I unplugged the timer and sure enough, the motor winding was open. Replacing the defrost timer fixed my problem. Troubleshooting (using the information available on your web site) took a little... Read more

I replaced the defrost timer. It's a 27 year old Montgomery Wards refrigerator and I couldn't find the correct timer anywhere until I contacted AppliancePartsPros. Great service. Read more
