Another GE refrigerator problem
Posted 03 May 2005 - 03:09 PM
I really don't want to have to buy a new fridge, but I've about had it with this thing.
Thanks in advance for your help.

In this GE, "evaporator temp sensor" is used in place of conventional defrost thermostat.
The evaporator temp sensor seems OK .
The defrost heater looks dark, but has continuity.
The "defrost thermostat" seems like it might be the culprit. It has continuity when cold AND when warm.
The "defrost thermostat" you mentioned should be called "defrost thermo-fuse" which will cut-off the heater supply if the temp is above 140 deg F. The "defrost thermo-fuse" seems OK.
If the fan winding is electrically test OK and is mechanically free to run, then there is "no voltage supply to this fan".
The fan tests OK but will not run.
Would this cause the evaporator fan not to run?
The remain cause could be:
a) "fresh food temp sensor" is bad; or
b) "electronic control board" is bad.

Thanks for the input. The motor has been replaced with a new one. Relatively cheap, and I was hoping for a quick and easy fix. I was really hoping not to have to replace the mother board.
Where is the fresh food temp sensor and how can it be checked? Is it near the damper? I can't seem to find it.
That's great to know that you're supposed to replace the board and the evap fan at the same time.

What readings can I look for at the evap fan connector? I know the red wire is 13v+ constant. I am assuming the white wire is ground. What should I see on the blue and yellow wires? I just want to make sure the mother board is bad before I replace it too.
