When using the microwave, the fan does not come on for about 20 to 30 seconds. Is this normal? Do I need a repair part? Thanks, Jay
Answer Hello Jay,
The magnetron cooling fan should run the full time the magnetron is running. If not, you either have a bad door switch W10211974, W10211974, or W10211972, or a bad 12Vdc power supply to the fan motor. This power supply is a part of the control board 8205421. By the way, the previous was not a typo. The unit uses two of the same switch in the door switch assembly. Be sure to put the switches in the correct locations.
