Rich for Model Number JTB2188AE Jenn Air Refrigerator I have noticed over that last few days that the unit was not running and the freezer was starting to thaw. It did not seem that it was in the defrost cycle as the heater was not on or warm. The evaporator fan, compressor and condenser fan were all off. Looking at the schematic it looks like the temp control or defrost timer could interrupt this. How would I check the defrost timer and does the temp control have to be made to go into defrost??
Answer Hello Rich. When the unit is off, you can turn the timer manually. If ti starts and runs, then the timer is sticking and will need to be replaced. If it does not, then most likely the temp control is bad and will need to be replaced in the unit. Read More... Answered by AppliancePartsPros.com | Tuesday, July 23, 2013
