GE Microwave Not Working Fixes

GE Microwave Line Fuse

The line fuse will break if too much current is passed through the circuitry of the microwave. The microwave will not start if the line fuse is blown. Multimeters can be used to check continuity. Replace the fuse if it does not show continuity. You should also investigate the cause of the fuse blowing and fix it. The new fuse may also blow if you do not resolve the problem. Warning: Its capacitor can still store thousands of voltages even after unplugging the microwave. It is dangerous to replace electronic components of a microwave due to the possibility of electric shock. The line fuse should only be replaced by a qualified technician.

GE Microwave Switchholder

The switch holder for the microwave is located behind the control panel. The microwave may stop working if the switch holder has been damaged or misaligned. Uninstall the control panel to inspect the switch holder. Make sure it’s in good shape and is secured correctly. If necessary, replace the switch holder.

GE Microwave Main Control Board

The main control board may have a defect. This is rare. Control boards are frequently misdiagnosed. Check all the most common defective parts. Replace the main control panel if you’ve determined that the other components work correctly. Warning: Even after unplugging the microwave, its capacitor can still store thousands of voltages. It is dangerous to replace the electronic components of a microwave due to the risk of electric shock. The main control board should only be replaced by a qualified technician.

GE Microwave Thermostat

The thermostat will trip if the microwave is overheated and cut the voltage. The thermostat may be shorted and not allow voltage to reach the high-voltage components. Test the thermostat with a multimeter for electrical continuity to determine if it is at fault. Replace the thermostat if it cannot be reset and does not show continuity.

Incoming-Power Problem

Electrical outlets may not receive power. If you need clarification on whether an outlet has power, plug something else in the outlet. Check your circuit breakers or fuse box if you cannot get power to the outlet.

GE Microwave Thermal Fuse

The thermal fuse shuts off the power to a microwave if that microwave overheats. Use a multimeter and test for continuity to determine if a thermal fuse is blown. If there is no continuity in the fuse, it should be replaced. Thermal fuses cannot be reset. They must be replaced if they are blown. (Caution: A microwave oven’s high voltage capacitor can store thousands volts even after it has been unplugged. The risk of electric shock is high when replacing the electronic components within a microwave. Only a certified technician should do thermal fuse replacement.

My dryer was giving me problems so I decided to give SD Appliance Repair a try. They were friendly. They were willing to work around my schedule. They came within 24hrs. They fixed my dryer within an hour. I will definitely call them again if I need another repair!.

Carlos Mason

VERY responsive! I called the guys on Thursday afternoon for a dishwasher issue and they came by the next day to diagnose the problem. Turns out I needed a new motor, which the guys ordered, picked up on a Saturday morning, and installed right away.

I had a hard time finding someone who would work on my stove be course it was quite old. The repairman arrived during the time they said he would, diagnosed the problem, and fixed it for a reasonable price. I will definitely use them again!
