Who knew it was so easy to get inside a microwave! Got a Panasonic Inverter microwave off Freecycle months ago and just recently it's taken 5, 10, 15, 20 attempts to get it to start. A little googling and I found out Panasonics have a very weak flap of metal that can't stand up to the pressure of repeated door closings. I opened it up, straightened the two metal flaps, and braced them so it won't happen again. Thank you google and youtube! The kids were so frustrated they were definitely ready to throw it out the window!
