Do-It-Yourself Stories from Customers like You The defrost heater would not work John R. • Lumberton , MS • May 21, 2019

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.

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.

I replaced the Thermostat and Defrost Timer. It was a fairly easy repair other than removing the old Defrost Timer. The way the manufacturer, in this case, Amana, mounts that unit with "clips" is just poor design and engineering. It is virtually impossible to get the timer out without damaging the mounts.
