Fridge temperature display doesn't match reality until power cycle
I have a recurring problem with a GE Profile PSB48LSRABV. Here’s an example sequence:
- Fresh food compartment set to 37F on the control panel (for months)
- Thermometer in fridge reads 46F (with lots of water inside per manual)
- Press “Display Temp” button, display shows fridge at 37F
- Turn power off, count to 15, turn power on, wait for control panel to boot
- Press “Display Temp” button, display shows fridge at 46F (matches thermometer!)
- Compressor runs and cools fresh food compartment
- Hours later thermometer in fridge reads 37-38 (yeah!)
- Press “Display Temp” button shows fridge at 37F
- Within days, the fridge is warmer inside again, thermometer inside reads 45+, but display reads 37 - unit needs to be “rebooted” again!
Fresh food thermistor from top of cabinet measured properly in ice water (and warmer water), the unit has always passed all the self-tests, and condensor coils and fan are clean, so I had techs come give it a shot under home warranty:
- Trip 1 - Tech came to assess, ordered new evaporator fan
- Trip 2 - Replaced fresh food evaporator fan (note new fan is working in fridge, and old fan works fine on bench)
- Trip 3 - Ordered main computer PCBA
- Trip 4 - Replaced main computer PCBA
Unfortunately, it continues the same cycle of misreading the temperature until power cycles, and taking a day off of work for each visit is getting painful.
Questa è una buona domanda?
