Electrolux Microwave exhaust fan not working
When an Electrolux over-the-range microwave exhaust fan is not working, start with the door switch, which must signal the control board that the door is closed before the fan can operate. Test the primary, secondary, or monitor door switch for continuity and replace any switch that fails. Next, inspect the exhaust fan motor. The fan blades should turn freely by hand. If they do not, or if the motor has incoming power but will not run, replace the exhaust fan motor. A defective thermostat can also prevent the fan from turning on, so test it for continuity. Check the grille for grease buildup, blockage, or visible damage that restricts airflow. If the motor is not receiving power, the control module could be faulty, although it is less likely than the motor or wiring. A separate micro switch may cause the same symptom and should also be tested. Enter your Electrolux microwave model number to find the exact replacement part. Unplug the microwave before service. Any repair that requires removing the outer cabinet exposes a high-voltage capacitor that can store lethal charge even when unplugged. It must be properly discharged before interior work, so contact a qualified technician if you are not familiar with capacitor discharge procedures.
01 - Electrolux Microwave Door Switch
A defective door switch may not signal the control board that the door is closed, which can prevent the button that controls the exhaust fan from functioning. To determine if any of the door switches are defective, use a multimeter to test each of the switches for continuity. If any of the door switches do not have continuity, the switch or switches should be replaced.

02 - Electrolux Microwave Exhaust Fan Motor
To determine if the fan motor is defective, remove the fan motor from the microwave and try turning the fan blades by hand. If the blades do not turn freely, replace the fan motor. If the fan blades do turn freely, use a multimeter to test the motor for incoming power and for continuity. If the motor has power but won’t run, replace it. If the motor does not have continuity, replace it.

03 - Electrolux Microwave Thermostat
The thermostat monitors the air temperature and turns on the fan when necessary. If the thermostat is defective, it won’t turn on the exhaust fan at all. Use a multimeter to test the thermostat for continuity. If the thermostat does not have continuity, replace it.

04 - Electrolux Microwave Grille
A damaged or clogged grille can prevent the air from being properly exhausted when the exhaust fan is turned on. Confirm the grille is free of obstruction and, if the grille is visibly damaged, replace the component with a new one.
Highly Likely
05 - Electrolux Microwave Control Module
If the microwave exhaust fan is not working, the control module might be defective. However, this is not usually the case. Before replacing the control module, first check the exhaust fan motor and wiring. If the exhaust fan motor is not getting power, the control module might be at fault and require replacement.

06 - Electrolux Microwave Micro Switch
A defective micro switch may not signal the control board that the door is closed, which can prevent the button that controls the exhaust fan from functioning. To determine if any of the micro switches are defective, use a multimeter to test each of the switches for continuity. If any of the switches do not have continuity, the switch or switches should be replaced.
