[FONT="]All,
I read some of the threads here and I find it very helpful thanks for the tips! I think I found the problem. Please review my findings and let me know if I’m on the right path:
Symptoms:
1. The unit kept on running all day/night long.
2. Temperature on the refrigerator side kept on getting warmer and warmer.

[FONT="]3. Freezer remained operational.
On thanksgiving, after we got all fat, I placed in a thermometer and found that it was 50F on the refrigerator and about 0F in the freezer. I immediately placed all leftovers in our basement Fridge and left it operating to see if there was any change in temperature. Next day the fridge side was still at 50F.
I goggled my symptoms and I found this and the service manual that was posted by someone on these forums:[/FONT]

[FONT="] Upon figuring out was everything was, and I had all the tools available, I went ahead and took off the back panel on the freezer side. When I opened it up I found the following snowy picture.[/FONT]

[FONT="]Yes that’s ice on the top right, not the plastic cover [/FONT]
J[FONT="]. No wonder why cold air was not getting to the fridge side.[/FONT]
[FONT="]I went for the easy stuff first and removed the defroster assembly and placed it on my desk. I checked the OHMS on the heating element. It hovers around 23.8-24OHMS which is normal according to several threads on this site. Then I checked the defroster thermostat. According to the service manual in section “AIR FLOW - FORCED AIR SYSTEMS” (Section 2-15-16 or page 44) section 5 and 6 state that the thermostat can be checked if the temperature is higher than 15F. Since I took the assembly out and it was in room temperature, I was able to read a resistance of 244K OHMS.[/FONT]
[FONT="]To add to this as well, i found the return vent full of ice as well.

[FONT="]Conclusion:[/FONT]
[FONT="]The defroster system did not come on due to the resistance of the thermostat at 244K in room temperature. It should read (infinity). Therefore never turning on and eventually causing the air tunnels to freeze. Since this unit has dual thermostats, the refrigerator side was never cold on enough for the compressor to turn off.
