The most common cause of that is a shorted or blown high voltage rectifier diode.

SOURCE: 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.

Kenmore model 721 - Cooked a meal for 30 minutes. Afterwards the microwave did not heat. However, the next day it worked. A few days later, was operated for 20 minutes, and again did not heat, and has not...


Yes, there is a thermostat device located on the magnetron. It will open up (turning off the magnetron) when it gets too hot, and it will reset automatically after it cools back down (in 5 to 15 minutes). The question is, Why is is over-heating? Usually it is caused by the exhaust fan being turned the wrong way. (For example, it may be set to exhaust the air out through the top of the microwave, but you don't have a vent there.) That fan can be turned to exhaust air out the top, out the back, or recirculate the air back through the front of microwave. It's easy to turn it around - the hard part is that you have to take the microwave down to be able to pull the fan out and rotate it the right direction.

Controls, heating and turntable function normally, but there is an intermittent failure (approx 80 of the time) where the interior light and blower do not function when the microwave is operating .

1)

  1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
  2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.
2)
  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.

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 doesn't, replace it.
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.1_24_2013_5_50_54_pm.gif1_24_2013_5_53_00_pm.jpg

Most likely you have a magnetron problem. Easy to replace (DYI) but make sure the high voltage capacitor is fully discharged first against the case.
