🔧 Find the Right Part for Common Microwave Problems:

High-Voltage Diodes

  • Restore heating function
  • Common fix for a microwave that runs but doesn't heat food

Microwave Fuses (Thermal & Ceramic)

  • Protect the appliance from overheating or power surges
  • Replace blown fuses that prevent your microwave from turning on

✅ Microwave waveguide cover

  • Microwave waveguide cover: A thin mica (or special plastic) sheet inside the microwave that covers the waveguide opening. It lets microwaves pass into the oven while protecting the magnetron from food splatter, grease, and moisture. If it gets dirty, torn, or burnt, it can cause sparking and needs replacement.

Door Switches & Interlock Switches

  • Control microwave start-up and safety interlocks
  • Solve issues like "door open" errors or microwave not running

Interior Bulbs & Light Assemblies

  • Replace dim, flickering, or burned-out bulbs
  • Improve visibility and cooking accuracy
