Freezer section not working. Fridge side maintained a 40 degree temp Richard A. • Cromwell , CT • June 30, 2017
After doing a lot of web searching about the problem.
It all came down to AppliancePartsPros.com.
Watching the repair videos and learning what to do made the job a breeze.
The only difficult problem was to thaw out the ice build up on the coils, which took 2 hours.
The rest was easy. now I have a freezer/ fridge that is working like new.
The total cost of the parts was less then having a repairman come out to look at it.
AppliancePartsPros saved me a lot of money.
Thanks!

Breaker was tripping when going into defrost mode Paul G. • New Fairfield , CT • December 08, 2014
Inspected the Defrost timer and it seamed to be functioning properly. Ohm ed out the defrost heater element and it also measured out correctly (mine 34 ohms). Bypassed the heater element and found that the unit would run without tripping breaker during defrost cycle. At this point i inspected the wiring to the heater and checked continuity of the wire and continuity to ground, No issues found. So with the heater out of the circuit and not having an issue i ordered heater element from...

Ice "lava flow" inside the freezer Kenneth C. • Alamo , CA • February 01, 2018
Firstly, the Ice Door had a kink in the edge, which caused it to stay open and create lots of frost on the coils. $5.00 part, highly recommend it. (By the way, the new door was little too big and it too stay propped open and left a gap so I had to trim the top edge of the rubber with scissors to get it to fully close.) Secondly, there are two heaters for the defrost cycle, one that goes around the coils and another attached to a collector pan beneath the coils. When the cycle hits, those...

Defrost cycle was not working frost in the freezer department Charles B. • Yorktown Hts. , NY • September 19, 2014
First replaced defrost timer which tested OK - but reasonable price and easy to replace. When that did not fix the problem replaced the defrost thermostat and defrost heater. That fixed the problem. However all three parts tested OK ?? May have been a loose connection or intermittent problem with one of the parts. Final cost for all three parts was much cheaper than a service call!!

Ice build up in top freezer of refrigerator Kevin S. • Mission Viejo , CA • May 13, 2015
After watching numerous videos I was able to discern that the problem was with one of the following: the timer, the heater, or the thermostat. a short time check showed me that the timer was working so that narrowed it down to the other two. Not having the necessary tools to check those two I ordered both parts. Once the parts came and I took out the old parts it was quite evident that it was the heater since it had black burn marks on it. I decided to install the thermostat also since it...

I tested the thermostat, mechanical defrost timer, and the defrost heater with a ohmmeter and determined that the heater was bad.
NOTE: Thermostat must be cold in order to be tested; otherwise, the switch inside won't close and you won't get a reading from the ohmmeter. Take a can of compressed air,...
