If the door of either the fridge or freezer is left open for more than about 20 minutes, the freezer and fridge temp then creeps up, with the fridge ending up in the mid 60s, and neither will cool down. If the entire unit is turned off for about 24 hours, alot of water ends up in the pan below (this may have nothing to do with problem–just noting it). Then power up and it will return to normal operations.
Sometimes this problem shows up even if no one leaves the fridge or freezer door open, but usually that’s what it takes.
No strange noises. All the fan intakes are clean.
Power down 24 hours per above.

Hello
This sounds like you have a part of your defrost system is defective. What is happening is the unit defrost heater should come on 3-4 times in a 24-hour period to defrost your evaporator. When the defrost system is not working and misses 6-10 defrost cycles, the evaporator becomes a solid block of frost and the unit will not cool in either section. That is why when you shut it off for 24 hours and turn it back on the unit cools normal again for the 2-3 days. To diagnose the defrost system see the steps below. Also see the complete service manual link below. Matt Ace technician
To enter Forced defrost, first press and release “ACTIVATE
CONTROLS”, then press and hold “HIGHER” pad, then press and hold “DISPLAY OFF” pad until you get an
audible consisting of three beeps.
This causes the control to immediately suspend all temperature control operations and start a defrost cycle, regardless of compressor dwell time and defrost start delay.
If defrost terminator temperature is satisfied defrost heaters will come on at this time for a normal defrost cycle.
Forced defrost will terminate when defrost terminator opens (completion of cycle defrost) or if forced pull-down is initiated or if there is a long power loss..
When forced defrost is initiated the temperature numbers are replaced with “dEF” in the seven segment displays, as
shown above. When defrost is complete the displayed “dEF” will again be replaced with displayed temperature numerals.
