Ikea Microwave exhaust fan not working
If your IKEA microwave exhaust fan is not working, start with the door switch, the most likely cause. A defective door switch or micro switch may fail to tell the control board that the door is closed, preventing the exhaust fan from operating. Test each switch for continuity and replace any switch that fails. Next, check the exhaust fan motor. Turn the fan blades by hand to make sure they move freely, then test the motor for incoming power and continuity with a multimeter. If the motor has power but will not run, or lacks continuity, replace it. A faulty thermostat can also keep the microwave fan from turning on, while a clogged or damaged grille can restrict airflow and make the microwave vent not working or not pulling air properly. If the motor is not receiving power, the control module may be defective, although it is less common. Enter your model number to find the exact replacement part for your IKEA microwave. If repair requires removing the outer cabinet, unplug the microwave first and remember that its high-voltage capacitor can store a lethal charge even after unplugging. Proper capacitor discharge is required before interior work, so use a qualified technician if you are not familiar with that procedure.
01 - Ikea 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 - Ikea 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 - Ikea 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 - Ikea 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 - Ikea 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 - Ikea 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.
