Microwave sparks Brand: Whirlpool Model Number: mt9101sfq-1 Age: 1 - 4 years when using microwave it starts to spark. there's a metal plate inside microwave that seems to be burnt. a co-worker told me that piece may be called a "plate air" and may need to be replaced. was wondering if anyone have run across this problem before and if so, is it worth having fixed |
