WARNING!
ARCING
If you see arcing, press the CLEAR/OFF button and correct the problem.
Arcing is the microwave term for
sparks in the oven. Arcing is caused by:
„ Metal or foil touching the side of
the oven.
„ Turntable ring support not
installed correctly.
„ Foil not molded to food (upturned
edges act like antennas).
„ Metal, such as twist-ties, poultry
pins, or gold-rimmed dishes, in
the microwave.
„ Recycled paper towels containing
small metal pieces being used in
the microwave.
