My refridgerator (1992) is not keeping temperature cool, and I believe the thermostat is not operating properly. The compressor/fan does not turn on consistently when warm, sometimes not until the temperature is above 40-degrees F. When it is on, the unit cools appropriately and quickly.
With the age of my unit, should I replace the evaporator fan for the refrigerator at the same time? The fan is currently working, but if it is easily replaced at the same time with very little additional work, I might proceed.
Also, should I preemptively replace the freezer thermostat and fan? I am replacing the defrost timer.
