I need some help please,
My microwave works perfectly unless I have multiple items to heat, requiring more than 5 or so minutes.
I can open and close/restart cooking, all seems well, then at a certain point, it appears to still be working,but the food just does not heat. You would be hard pressed to tell its malfunctioning, no odd noises or smells, all appears ok. But the food stays cold.
If I open the door and let the unit cool for 15 or 20 minutes again it works perfectly again until it gets hot again.

Any help would be appreciated. I was thinking the magnetron but from what I've read, once those go, the unit wont work at all again.
This is very frustrating since it only happens when my entire family is having dinner and we need to heat up three or four things. Any ideas??

Thanks

Rich
