Refrigerator is approx. 3 years old, and i have have had multiple techs come out to look at the issue with my refrigerator. Problem: Temp is not consistent in the upper section only - freezer compartment has never had any issues. Only the top section. Temp set to 35 deg in refrigerator and it will hover around 42 deg. I have had the main board replaced, ice maker door replaced, and i think a few more things - mostly under warranty. Problem ONLY occurs after there has been a power interruption. Seems to me after the technician runs it through the diagnostic mode - everything checks out - it will go back to running properly. Until the next power interruption. I don't mean a prolonged outage, but just a short flicker or the latest - turned the main breaker off for less than a minute. Techs have come to service and say the temps are within range 40 deg even though its set on the lowest temp. I know the difference between COLD milk and not so cold milk ( yeah - we'll go with milk ) Again, never an issue with the freezer section. After the last service call ( Nov 2019 ) is has ran flawlessly until I turned power off. Is there a way to reset the computer or are the techs and whirlpool service missing something here. Please HELP - this is getting frustrating and COSTLY
