We will cover the possible solutions one by one to help you fix this annoying microwave issue.

Microwave Has Power but Not Working Issue

Before we proceed with a detailed explanation of the causes and their solution, I want to you to first check the GFCI and reset it. If it’s alright, only then carry on with the other solutions explained below:

#1: Thermal Fuse

The fuse protects the microwave from overheating.

To check if the fuse is fine, you will have to make use of a multimeter. If there is no continuity in the fuse, then you need to replace it.

#2: Microwave is Buzzing but not Heating Properly

If your Microwave is buzzing but doesn’t heat properly, then the problem might be because of the defective power diode.

The power diode is necessary for heat production in the microwave. If it doesn’t work properly, the microwave cannot produce enough heat.

#3: Door Latch

When the door of the microwave isn’t closed completely, the microwave doesn’t work properly.

Inspect the latch to make sure that there are no problems with it. Make sure to replace it if there are issues with it.

#4: Door Switch

The door switch is a component that is closed when microwave door is closed.

To check if there’s any problem with this switch, use the multimeter. Replace it in case of any issues.

#5: Sparks inside the Microwave

If you experience this problem, immediately turn off the microwave, and let it cool down. After some time, remove the thing that you have placed in the microwave, wait for a few more minutes

, and then power on the microwave.

The food itself might be causing this problem in some cases. Thus, cleaning is advised.

Final Resort: Calling a technician

If none of the above methods works and your microwave is still not working, then it is advised to call a technician.
