My refrigerator seems to quit working after a couple days. I thought it was not defrosting so we unplugged for 24 hours. After this we plugged it in and it all gets cold and good to go for 3-4 days and then there seems to be no cold blowing in from the vent.
Answer Hello Dan,
You need to remove the back wall of the freezer compartment and look at the frost pattern. If the evaporator fan motor isn't running or is running too slowly, the fan motor W10128551 will require replacement. If the fan is running and starts back up on its' own after you stop the blade, the problem is probably a defrost issue.
The most likely cause of the issue if there is a frost build-up and the fan motor is operating normally is the defrost thermostat W10165425. It should read continuity when the part is down to temperature. If it reads good, the defrost heater 12729128 could have burned out or the electronic control W10503278 may have an issue.
