why does my microwave turn off after 3 minutes
Hello, when the microwave shuts down, it means that your magnetron is overheating. Now the microwave can over heat for 2 reasons. One is that the fan inside the microwave isn't running when you turn the microwave on, which means that the magnetron is not cooling down.The other possibility is that the magnetron is just getting too hot and the magnetron itself will need to be replaced due to it overheating.ello, when the microwave shuts down, it means that your magnetron is overheating.
