GE Refrigerator/Freezer PTS 25 LBM
Posted 03 April 2005 - 06:01 PM
Freezer on top and Frig. on the bottom. Lots of frost on
the meat and stuff. Thermometer measures about -10 degrees
below 0. Reduced the freezer digital control from a 5 to a
3. Still too cold. Refrigerator temperature okay. Any ideas? Bought this thing a little over a year ago. Yeah, out of warrantee. Just my luck! Should have bought an Amana.

Check your door gaskets carefully. This requires keen powers of observation. Many times, I'll go to a house with this exact problem and it always turns out to be a door sealing problem. They never believe me until I fix it and the problem goes away. On a new fridge like yours, I'd suspect that the cabinet isn't square and this is creating a gap somewhere in the sealing surface.

Samurai, I've ran into this very issue with GE products in the past. It's certainly worth checking.

quite understand why my freezer temp went from 0 to -10. Would air leak around the gasket cause this? Would a bad
defrost heater cause this frost buildup if my gaskets are okay? What about a bad thermostat allowing the compressor to run longer than it should. Would that lower my freezer temp?

Does your GE fridge have "Upfront Electronic Digital Display which displays exact temperatures for the fresh food and freezer compartments"?
If so, this fridge has electronic temperature sensors (NTC themistors) and electronic control board instead of mechanical thermostat.
The "electronic control" fridge usually controls the temp of the fresh food and the freezer independantly by 2 thermistors.
In your case, the "freezer" thermistor could be bad (either short-circuit or out-of-range)
The "frost" water could get into the "freezer" thermistor if the thermistor is "crack" and it will cause a "short-circuit". The control board thinks the freezer is not cold enough and continue to cool it to an abnormal low temp.
You may have to check the "freezer" thermistor according to the specification from GE manual.

For years Good A/C techs have been installing "drip loops" in their fan motor wires to keep water from following the wire into the motor. Might not be a bad idea look for, and add as needed to the evap thermistor, every time you have the evaporator cover removed.
