microwave heats properly. the fan will not turn on during heating The fan only works on high. I have to manually turn the fan on when heating and only high works. All other functions seem normal
ANSWER Scott, Based on your post information, the issue is most likely in the electronic control board 8206448. You should check the low speed motor windings with a multimeter. Across the red and blue wires you should have a resistance of 75 to 120 ohms.Across the blue and white wires should have 40 to 65 ohms resistance. If the resistances are in range, the motor is fine.
