How Do You Fix A Microwave That Is Not Heating?
If a microwave isn’t heating, there could be a few different issues causing the problem. First, make sure the microwave is plugged in and the circuit breaker hasn’t tripped. If those things check out, test the door switch, which could be malfunctioning if the microwave won’t start at all. Another potential issue is a faulty capacitor, magnetron, or diode. These are more complicated and should be checked by a professional technician. If the microwave is over 5 years old and the repair is expensive, it might be more economical to replace it.
