Fix frost buildup and warm fridge issues with this adaptive defrost control board. Solves freezer icing and defrost cycle failures. Moderate DIY repair.
The 20 year old unit still serves us well, looks good and has been kept in good repair. The condenser fan had stopped so I removed, cleaned and oiled that motor. The decision was made to make an upgrade to the evaporator motor and control units so that the appliance could reasonably be expected to have extended service life. The Ice maker module had been replaced 7 years ago. I ordered the parts and have made the upgrade for temperature controller and the defrost control. If you are in a... Read more
Fix frost buildup and warm temps in your freezer with a new defrost timer. Restores automatic defrost cycles. Straightforward DIY repair.
Replaced the defrost timer. It was not located where the parts explode suggested in the thermostat control box which is located in the upper right corner of the liner. It was in fact outside the freezer compartment on the back lower left support (when looking at the back of the freezer). It is secured with 2 sheet metal screws with a 1/4 hex head. The manual override dial is visible through a punched hole in that support. Just remove the 2 screws, disconnect the electrical connector. Then... Read more
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. 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. (which it seems was was still functional). Between that and cycling some ice packs up from the still working... Read more

Fix freezer icing and warm fridge temps by replacing a faulty defrost timer. Typical DIY repair takes 15-30 minutes with basic tools and a multimeter.
I took the bottom tray out of the freezer and found the coils iced up severely. I was reasonably sure the defrost timer was the problem and your tech said that was a good possibility. 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
Fixes refrigerators that won't cool or have excessive frost buildup. This defrost timer cycles frost removal every 6-12 hours. DIY-friendly repair.
This unit has a recurring problem with the defrost timer. after the first 10 years the original part gave up. we had it replaced and (as normal for me i watched very closely) . after 2 years the same trouble started again. the defrost cycle would run to long. so i replaced the same part and solved the trouble again. so now about every 2 years this part wears out again and i order it and replace it. this has gone on for 20 years now and this unit is still going strong after serving us for 29...

This defrost timer cam replaces the plastic cam on a mechanical defrost timer. It restores the timer's changeover between cooling and defrost, helping prevent frost buildup on the evaporator and temperature swings inside the refrigerator.
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. I had to do some creative rework to mount the new timer. After 2 days, the fridge appears to be working properly with these new parts. The new parts were shipped Very Fast...APP is... 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
