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.

When to Call a Professional

Call a qualified repair technician if:

• The microwave makes strange noises
• You see sparking inside
• Basic troubleshooting doesn't solve the problem

Prevention Tips

• Don't run the microwave empty
• Clean it regularly to prevent food buildup
• Avoid slamming the door
