Why does it turn on to heat soon as I close the door?
GE Profile (PEB1590DM2BB) turns on magnetron as soon as door closes. Fan and turntable don't turn on, unless time is entered then it operates normal and light, fan, and turntable shut off with timer - magnetron keeps heating until door is opened. If I make the bottom microswitch nothing happens, the top latch doesn't appear to have a switch, just a latch. I've unplugged it and waited, but problem remains. I haven't taken it apart yet as I'm hoping someone has had the same issue and can guide me in the right direction before completely tearing it apart! Thanks in advance and a safe, healthy happy holiday season to all.
