Arcing or Sparking (1)
○ Question
Is the unit empty?
○ Detailed Answer
The microwave should NEVER be operated empty. This is because there must be something inside the unit
to absorb the microwaves or the cavity will be burned/scorched. Place a cup of water in the microwave and
“cook” for 30 seconds. If no sparking, then it is okay to continue to use.
