By: Whirlpool

Part Number: W10822278

Symptoms of a bad Defrost Timer include:

Excessive frost buildup in the freezer compartment

Do-It-Yourself Stories from Customers like You Defrost not working on upright 20 year old freezer W D D. • Spring , TX • September 19, 2014

A word of thanks to AppliancePartsPros - they delivered in one day. Ordered at 4PM CDT and received the part by noon the next day. Also, Alicia in the help department was able to locate an electrical diagram for my old freezer. This was essential for proper setup and her persistence in tracking down the diagram was top notch.

Do-It-Yourself Stories from Customers like You Amana br18vw refrigerator wasn't staying cold Adrian B. • Chicago , IL • February 08, 2015

I am not new to APP, fixed a tub belt on a Maytag dryer in the past. My frig started getting warm so I went onto to one of those "lists" sites and found a appliance repair place. The guys were great and came out right away. The tech said it was the cold control and $260 later my part was replaced, about 30 minutes. Great I thought until my frig started getting warm again. Those cold sensors on the beer bottles are a great indicator. Not wanting to spend another $260 I looked up on APP to see if... Read more

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. You-tube had plenty of videos on replacing those parts and even before they arrived I was able to add a switch and bypass the broken thermostat and start a cycle manually with the timer.

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.
