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.
Any ideas?

The ACTUAL TEMP light will come on and the display will show the actual temperature. To change the temperature, tap either the REFRIGERATOR or FREEZER pad until the desired temperature is displayed. To turn OFF cooling system, access SETTINGS from the HOME screen. Page over and tap COOLING SYSTEM ON.

Press and hold temp up button then press quick freeze button at the same time, your temp settings will be displayed on display for fridge and freezer, fridge temp is + and freezer -, cycle by pressing quick freeze, set temps by up and down temp buttons, once done, push vacation button. your temps are now set, turn the unit off for 2 mins the turn on. reaction is now set and normal. regards Russ

Here is a link to the main GE Support page for your refridgerator:

And here is a link to the Online User's Manual with the operating instruction for it:

See page 5 of the User Manual for detailed instructions on how to adjust the fridge and freezer temperatures. It reads as follows in the manual:

To change the temperature, press and release
the WARMER or COLDER button. SET will illuminate in
the display, as well as the set temperature. To change
the temperature, tap either the WARMER or COLDER
button (while SET is illuminated) until the desired
temperature is displayed. Refrigerator temperatures
can be adjusted between 34F and 47F and
the freezer temperatures can be adjusted
between 6F and +8F.

Once the desired temperature has been set,
the temperature display will clear after 10 seconds.
To display the temperature, the DISPLAY TEMP button
may be tapped.
Several adjustments may be required. Each time you
adjust controls, allow 24 hours for the refrigerator to
reach the temperature you have set.

Self Diagnostics
To enter Self Diagnostic mode, both temperature control panel displays must be illuminated. A display
can be illuminated by pressing an adjacent temperature adjustment button. When both displays are
illuminated, set the freezer and refrigerator temperature settings to 5. Simultaneously press and hold all
4 temperature adjustment buttons for approximately 3 seconds. A flashing 0 in the refrigerator and
freezer displays will indicate that the refrigerator is in Self Diagnostic mode.

For temperature control panels with single-digit displays, the COLDER temperature adjustment button
will increment the numbers up and the WARMER temperature adjustment button will increment the
numbers down. Use the freezer temperature adjustment buttons to enter the test code number in the
freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in
the refrigerator display. When a test code has been entered, the displays will flash to confirm the test.
Press the HOLD button for 3 seconds to begin the test.
For temperature control panels with 3-digit displays, the COLDER temperature adjustment button will
increment the numbers down and the WARMER temperature adjustment button will increment the
numbers up. Use the freezer temperature adjustment buttons to enter the test code number in the
freezer display. Use the refrigerator temperature adjustment buttons to enter the test code number in the refrigerator display. When a test code has been entered, the displays will flash to confirm the test
code. Press any button other than a temperature adjust button to begin the test.
When testing has been completed, do one of the following things:
• Enter code 1 5 to completely reset the system.
• Enter code 1 6 to exit diagnostic mode. GSS manual

Most likely it's not defrosting, many GE fridges need new defrost heaters every couple of years.

yes

Are numbers being displayed at all? If you want to confirm whether they are wrong or not, try putting a thermometer inside the fridge for about 10 minutes and check it against the temperature displayed. If it's wrong then it's probably the temperature sensor and would need to be replaced.

I suppose it's a long shot but could it be displaying 18 and feels more like 65? (Celcius vs. Farenheit)
