Power cycle the device
Turn off your GE Microwave completely. Unplug it from the power source if applicable. Wait 2-3 minutes, then plug it back in and turn it on. This clears many temporary glitches.

Clean accessible components
Clean all user-accessible parts — filters, vents, ports, and surfaces. Built-up dirt and debris cause a surprising number of device problems.

If That Didn't Work
- Check if the door latch is closing properly — the microwave won't run if it doesn't detect a closed door.
- Try a different outlet to rule out a power issue.
- Check if the turntable motor is working by listening for a humming sound.
When to Call a Professional
Microwave internal repairs involve dangerous high-voltage components. If external troubleshooting doesn't fix it, a new microwave costs $80-$200 and is usually cheaper and safer than repair. Never attempt to open the microwave cover yourself.
