Microwave-working-but-not-heating, when your microwave turns on but does not heat up, it may mean the door switch is broken. the door switch signals other microwave components to supply power when closed, and to stop heating when open. the door switch can also be called an interlock switch.. If your microwave oven doesn’t heat, you may have a problem with the magnetron. this component is part of the high voltage circuit and provides the microwaves that generate the heat. if the magnetron is defective, the unit may blow a fuse, or you may still have all other functions operating normally., new well explained video here https://youtu.be/sgj0hvi6aj4 if your microwave works, has power and timer runs but there is no heating, the most common problem....
Check the power. verify the power cord is connected to a grounded, operational outlet. check the outlet. if you are unaware if it's working, plug in a household lamp or other small appliance to verify that the outlet is working., maytag microwave not heating microwave may not heat because of a serious damage or some easily fixable cause: microwave may not work well due to low voltage. 220 v is a necessary value for normal operation of the magnetron. if the voltage is lower, it will work, but the temperature will rise very slowly..
Common solutions for: microwave not heating 01 - diode the diode converts the a/c power output of the transformer to d/c, doubling the voltage to nearly 5,000 volts. this high voltage powers the magnetron to heat the food., microwave runs but does not heat if the microwave runs but is not heating, it could be one of many components. make sure the “timer” function was not inadvertently used. check to ensure the door is closed firmly..
Your microwave may turn on but does not heat. remember the frying comment above, this is the part that will not just curl your hair, but will most certainly be a shocking experience. do not mess with it. the magnetron can be tested by setting an ohmmeter to its highest resistance scale., cooking appliances 12/19/2018 when the microwave oven does not heat, it may be caused by entering the wrong settings or an inadequate power supply. the microwave should display an error code if there is a severe problem which requires a technician.
