GE side by side wasn't working well, frozen items melting, fresh food not cool enough. When I checked I found the air vents mostly occluded on back of unit, condenser same. I cleaned everything up then looked at the evaporator which was completely frozen, which I eventaully thawed. Based on diagnostic testing determined fans, heater and defrost themostat were good.
When I immersed 2 of 3 thermistors in ice water for five minutes then tested resistance I got the following readings:
Freezer thermistor = 15.8K ohms
Evaporator thermistor = 13.25K ohms
Am I correct in my understanding that the reading should be 16.3K ohms + or - 5%, which would indicate the need to replace the evaporator thermistor? I also saw on your site that there is in upgraded thermistor available now, should I just replace both w/ the new version while I'm at it?
And my last questions are:
How do you test the fresh food thermistor which must be enclosed in the damper assembly from what I can see?
Is the thermistor replaceable or must the whole damper assembly be replaced?
