If your microwave isn't heating properly, don't worry! Here's a step-by-step guide to help you troubleshoot the issue.
Quick Checks First
- Make sure the door is completely closed - microwaves have safety switches
- Check if the outlet is working by plugging in another device
- Verify the timer is actually running when you start it
Common Issues
- Door Switch Problems The door switches prevent the microwave from operating when the door is open. If they're faulty, your microwave won't heat.
- Listen for a clicking sound when closing the door
- Check for any visible damage around the door frame
- Magnetron Issues The magnetron is what actually generates the microwaves that heat your food. When it fails, your microwave might run but won't heat anything.
- You might hear unusual sounds when running
- The microwave might make humming noises but not heat
⚠️ Don't attempt to repair a microwave yourself! They contain high-voltage components that can be extremely dangerous even when unplugged.

- The microwave makes strange noises
