Why won't it heat?
Microwave stopped heating up. Took old door switch/microwave switch/door switch assembly out. Noticed one door switch with burnt connector at wiring connection. Also, plastic frame slightly damaged. So, replaced with a new assembly. I bought on ebay for $16. Put it in and still microwave doesn't heat anything..but now convection oven is heating up the inside of oven when I press microwave button. When I put back 11 wired connectors to computer panel, they all fit as they are color coded and size coded....What could be problem?

My guess is that something has not been reconnected correctly, or there's a bad connection. I'd re-check all connections. If possible, use some electronic contact cleaner on the cables that connect to the control panel.
