GE Microwave not working

GE Microwave not working. GE Microwaves are kitchen appliances that most homes or apartments have installed in them for reasons other than just to heat food up quickly.

They can be used for defrosting, reheating, and even sometimes as a regular oven alternative if you add the necessary kitchenware of course.

Because GE microwaves have so many functions it’s crucial that all hardware is working properly or it could prove very problematic.

GE Microwave not working

Our comprehensive guide will explain the most common issues, offer tips, and show you how to take care of your kitchen appliance.

Problem with the Thermal Fuseproblem with the thermal fuse

If the microwave overheats, the thermal fuse will cut off the power. Test the fuse with a multimeter if you suspect the fuse has blown. (There’s no need for concern here; your microwave doesn’t store any terrifying amounts of electricity.

What you will find inside is called a high voltage transformer, although this doesn’t hold much more than 100 or so volts that’ll hardly be enough to shock you).

If the fuse has been blown, replace it with a new one just like before following manufacturer instructions carefully.

Defective Thermoprotector

If the microwave is overheating, it may be a sign that the protection thermostat is tripping. Test the thermal protector for continuity by placing the leads of a multimeter across the terminals of the fuse-like device. The thermal protector may need to be replaced if there is no continuity.

The main control board needs to be replaced

Controls can stop responding for many reasons. However, the mainboard is rarely defective. The processor and power supply will often get misdiagnosed to check whether other parts are causing the problem before replacing the control board. Replace the mainboard only if all other components have been tested and found to be functional.

An issue with Line Fuse

If an issue occurs that results in the fuse blowing out, make sure to look at the circuits and see if there might be some way of preventing this from happening again.

If not, it would be best to call someone who’s licensed to handle any microwave problems as taking it apart yourself can lead to some hazards, especially handling the high voltage capacitor even after unplugging.

Microwave plates do not spin

In a microwave, beneath the plate is a rotating motor that spins the plate. One of the main causes of this problem might be because the motor has worn out or otherwise stopped working properly.

The most common component that needs to be replaced in such a case is this faulty motor; however, if the motor is functioning correctly, then it’s time to check for problems in your microwave’s control board. If everything functions fine there as well, then you’ll have to examine your touchpad or control panel for an issue with it.

Microwave sparking

Sparking inside a microwave is common, but you shouldn’t assume the appliance has broken down right away. The problem requires that you turn off the microwave immediately and examine possible causes. Damaged waveguide covers, diode burns, damaged rack supports, or worn-out paint from the walls may all indicate these problems.
