Fine Your Idea

My-microwave-is-not-heating, the most likely reason why your microwave is not heating up is either the magnetron is damaged or the components that power the magnetron are damaged. mangetron assembly is the device that generates the microwave heat. so if you are sitting there and wondering why is my microwave not heating up, then the short guide here will help.. 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., 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..

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., if you notice that your microwave runs but doesn’t heat, there could be a problem with its high voltage diode, the component that powers the magnetron so it can heat up the food. the problem arises when this diode, which doubles up the voltage to as much as 5,000 volts to facilitate microwave heating, burns out..

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., 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....

When a microwave isn't starting or heating, the most common reason is because it is in demo mode. this mode is used on retail showroom floors to show off microwaves without activating their magnetron. the microwave also won't heat if it does not have enough clearance or ventilation., 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. close it firmly, but do not slam..

My first thought would be a blown magnetron. on microwaves, these can generally go dead, usually with a popping sound. i think there might also be a fuse in your microwave, but i do believe that if it was a blown fuse, your mw would not start up. the technician should also not forget the door switch since some of them can cause the same issue.
