Hi--
I have a GE Monogram with some common symptoms. The freezer side is cold ( zero degs) and the 'fresh-food' side is warm (58 degs). I have done a few checks, but I am at a loss as to what could be causing this.
Here's what I have observed/done:
1) The compressor is running.
2) I cleaned off the condensor.
3) The evaporator fan runs.
4) I checked the defrost thermostat and it is closed. I also checked the evaporator fan thermostat and it is closed. I checked these at the wiring hub on top of the refrigerator when the freezer was cold.
5) The damper is open and free of obstructions.
6) I tried to check the evaporator itself but there is styrofoam in the way( and I don't know how/if to remove this?). Instead I looked around the edges to peek at the evaporator. It does not appear to be excessively frosted or iced over from what I could see.
7) Originally there was a block of ice in the light shield in the freezer and damper, but I cleared this out.
8) I checked the airflow by defeating the door switches. The air flow in the freezer seems strong. The air flow out of the damper into the 'fresh-food' section is very weak unless I open the freezer door, then it is strong. The damper is open and clear, though. I am really confused by this unless the air flow is restricted by a slight vacuum when the freezer door is closed.
Can anyone recommend further diagnostics? I am really stumped by this.
Thanks,
Tim

An update:
Last night I defrosted the whole unit by 1) manually turning the timer to have it enter the evaporator defrost cycle and then 2) turning everything off to inspect the evaporator and clean out the drain tube.
After cooling it back down, everything is working fine again. Seems like ice was blocking a return flow someplace?

I am concerned too.
The evaporator drain tube seems poorly designed. The tube actually goes up to exit the freezer compartment, travels horizontally for ~8 inches, and then rises again into the compressor area. It is as if the designers planned for water to run uphill.
It was quite difficult to pull the tube to inspect for blockage and kinks.
I am worried that the problem will return once the system ices over again.

In the back of the fridg. you will find the defrost timer, turn it till the comressor stops, then check for defrost, if none you need to remove the evaporator cover in the top of the refrigerator section to expose the evaporator. If defrost, you will need to replace the defrost timer.
