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?
check your coolant. the temp is the water temp. Your radiator is out of water? you`ll burn out your water pump. Also check to see if your radiator fans are running constantly.
this should help you,, I'm not sure if you mean to the meter itself or to what your testing, this link helps with temp readings Hope this helps, if not,, reply back to me and let me know, and I'll find your answer

This clock keeps track of the temperatures for each of the last 12 hours. So on the bottom, you'll see the temp at 12 hours ago (-12), 6 hours ago (-6), etc. On the left side, you'll see the temperature in Farenheit go from +5.4 to -5.4 from where it is currently. So if the temperature is 70F degrees right now, and it was 65F degrees 12 hours ago, then it'll show -5 in the first -12 column. It will always be at 0 for the current hour on the right. The scale on the right is in Celcius so it does the exact same thing as Farenheit.
Thanks for using FixYa. Error F4 in your range/oven means oven temperature sensor failure. To resolve this issue you’ll have to check the oven temp. sensor circuit if the reading is more then 1100ohms then it should be replaced. Please do rate the solution if the issue is resolved or post a comment for further assistance.
