Why do my fridge temps fluctuate between 34 and 50 degrees
GE DFE29JGDCBB 10 years old. I have checked FF thermistor, FF Evap thermistor, cleaned the coils. Everything is running when asked to in diagnostic mode. RPM's show on all fans and correct temps vs. ohms show on thermistors. I set freezer to zero and fridge to 38. Temps on display show -7 and 38 even when the fridge is 50 degrees. When I reset the fridge via 016 on diagnostic, temps on display change, but they are still wrong. Could the thermistor be reacting too slow? Board not reading thermistor resistance and processing into correct temp? Could defrost timer be mis reading?
Also, when testing thermistor temps on display screen in diagnostic mode, an intermittent 101 shows up on the screen. Error code of some sort?
Esta é uma boa pergunta?

I reset the fridge this morning and watched and listened to everything. Compressor, Condenser Fan, Ice Box fan, Frozen Food Evap fan all turn on. The fridge has risen to 53 degrees and the fresh food evap fan is not running. As soon as it turns on, all is well. The fan is okay though as I have tested it. I tested fresh food and fresh food evap thermistor and they showed the correct ohms but they react slowly. Could their slow reaction be causing the issue? The temp display never shows what the thermistor value is when I put it in diagnostic mode and the temp probe I have in the fridge never matches either. Sometimes is only 2 degrees off, sometimes 10.
There is water on the back where the fresh food coils drain, so I know the heater is working. What could cause the fresh food evap defrost to turn on too frequently and last too long? The evap thermistor checks out with ohm readings, just slow to react.
