Whirlpool GH7208XR - Vent Fan Motor does not spin up

I have a brand new Whirlpool GH7208 right out of the box and installed yesterday. When I press the vent fan button, I hear the motor or relay get power to it, but the fans themselves don't spin. It sounds like a transformer hum. If I remove the vent filters and start the fans manually by hand while the swtich is turned on, The fans will start and spin up slowly. But then the fan switch seems to have no effect on fan speed, it always turns a the high or boost fan speed. Turning the fan switch to off will cut the power to the fan. If I turn the fan switch back on before fan stops spinning, then it will start back up again. If I let the fan come to a complete stop, it will not restart without a little hand spin. Any ideas?

I have checked all of the functions and operations of the Microwave and it all seems to be working fine. I have called customer support for warranty work but I want to see if anyone else has idea or suggestion before the repairman shows up.

Thanks, Steve

It's probably a shorted relay or triac on the control panel.

We repair these on a regular basis for customers nationwide with our guaranteed $39.95 service with a full one year warranty.

We have full details, plus critical safety, disassembly, and troubleshooting info at our site. You'll find a link to our site in our listing here on FixYa: http://tinyurl.com/yzjozk

NOTE: There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

Go inside and check all of the connections related to the fan. Check the fuses, and the fan itself.

We changed the charcoal filter & reset it. The vent fan still does not run. I cannot turn the vent on by pressing the vent button but the micro still heats up. What happened to the fan?


follow this steps and fix iT. God bless you


  1. Exhaust fan motorIf your exhaust fan motor is not running, there are a couple of things that you can check involving the motor to locate the problem. After removing the fan motor, you can manually attempt to turn the fan blades with your hand. If the fan motor is working properly, the blades should spin effortlessly. If this does not occur and the blades are taught, the motor will need to be replaced. Secondly, the fan motor itself can burn out due to time and usage. Using an ohm meter, the exhaust fan motor should read open for continuity. If it does not, then the fan motor has expired and will need to be replaced.
  2. ThermostatAnother part that could cause the microwave exhaust fan to not work is a faulty thermostat. A thermostat gauges the air temperature, which activates the exhaust fan when required. If this part becomes flawed, the exhaust fan will not energize and the thermostat will need to be replaced.
  3. Main control boardIf your exhaust fan is still not working and the microwave fan motor, wiring, and thermostat are operating accurately, the root cause could be with the main control board. Replace the main control board.

GH7208 no fan while cooking


If there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now switch the microwave power on and use a cup of water to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. Replace with same type. If not check the waveguides within the cabin for food particles that can burn and spark, check for rust that can corrode and spark when the ceramic paint has worn out.
If there is heating without any issues, you can use the microwave safely

Whirlpool model MH7100XYQ microwave, exhaust fan


sometimes the control board will short out and not let the fan or cook top light work.
if you want to try and remove the control board, look on the back of the board for any burnt off tracers. those are the wiring connections on the board that move power from a wire to a relay.
it is usually easy to see the burnt out piece, and if you can solder a new wire across where the burnt out part is, then it should work ok again.
if you cant solder, then a new control board will cost about 125-150 bucks.
