Goldstar Microwave exhaust fan not working
Is your Goldstar microwave exhaust fan not working? Start with the door switch, which must signal the control board that the door is closed before the fan control can operate. Test each door switch, including the primary, secondary, or interlock switch, with a multimeter and replace any switch that lacks continuity. Next, inspect the exhaust fan motor. The fan blades should turn freely by hand. If they do not, replace the motor. If they turn freely, check the motor for incoming power and continuity. A defective thermostat is another likely cause because it monitors air temperature and activates the fan when needed. If it has no continuity, replace it. A clogged or damaged grille can also make the microwave vent not work properly or prevent air from being pulled out. Less commonly, the control module may fail, especially if the motor is not receiving power, or a micro switch may be defective. Enter your Goldstar microwave model number to find the exact replacement part. Any repair requiring the outer cabinet to be opened must be handled carefully. The high-voltage capacitor can store lethal charge even when unplugged and must be properly discharged. Use a qualified technician if you are not familiar with capacitor discharge procedures.
01 - Goldstar 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 - Goldstar 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 - Goldstar 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 - Goldstar 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 - Goldstar 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 - Goldstar 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.
