Microwave vent fan won't turn off - Appliance Repair Forum

see this causes and fix it .God bless you
Exhaust Fan Motor If the exhaust fan does not run the fan motor might be bad. Remove the fan motor from the microwave oven and see if the blades can be turned by hand. They should turn very freely, if they're stiff the fan motor will need to be replaced. The fan motor can also burn out. To test this use an Ohm meter. The motor should have continuity. If it does
Thermostat If the microwave exhaust fan is not working the thermostat might be defective. The thermostat senses the air temperature and turns on the fan as needed, if it's defective it won't turn on the fan. Watch our video on testing thermostats.

Main Control Board If the microwave exhaust fan is not working check the exhaust fan motor and wiring. If they are good the main control board might be defective.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid with a one year guarantee.

Or you can buy and install a new smart board from the Pros here.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan, cooling fan, turntable, and/or inside light operation, too.

Details of our service are at our Web site, along with a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

Hello

Plug the microwave into the outlet if the microwave won't power up. Make sure the plugs on the microwave match the type of outlet. A four-pronged outlet can only be used with a four-pronged plug. Same with three-pronged outlets---they only work with three-pronged plugs.


Inspect the plug. Make sure it hasn't been cut or tampered with. Four-pronged plugs can't be cut down to fit a three-pronged outlet. Three-pronged plugs mustn't be forced into four-pronged outlets. A three-pronged plug mustn't be used in a two-pronged outlet, either.


Replace blown fuses, or if there's a circuit breaker, check it for tripped breakers. Sometimes the trip won't be obvious, so cycle the circuit breakers. Turn them all the way off and then back on again.


Plug another appliance in the outlet. You will find this easier with three-pronged appliances. Simply plug a toaster, or other appliance into the microwave's outlet, and see if it works. If it works, you know the problem is with the microwave, not the power circuit. Have the microwave serviced or replace it. If the toaster or other appliance doesn't turn on, you know the problem is with the circuit.

probably caused a short while replacing the bulb(s) and, causing damage to the circuit board. pull the board out and carefully check for burned foil traces; and rebridge with solder. it may or may not work. always unplug the microwave when replacing the range lamps.

The fan is needed to cool the magnetron. Without the fan it would overheat in seconds and destroy itself.

You need to hit clear or maybe clock. I believe on this model you need to set clock before you can do anything

Do you feel air flow? That's the key.

Most microwaves have the exhaust fan assembly at the back edge, not up front immediately behind the grille / vent.

Post back if you can give us more detail or have other questions.
