Arcing or Sparking – Empty cavity issue




○ Cause          

      Is the microwave oven cavity empty and operating?


○ Troubleshooting     

     The microwave should NEVER be operated empty. Reason being there must be something

     inside the unit in order to absorb the microwaves or the cavity risks getting burned or scorched.

     Place a cup of water in the microwave and “cook” for 30 seconds. If no sparking occurs, then it

     is okay to continue using it.
