Over-the-Range Microwave keep turning bad ---- Help!? I have a Maytag OTR Microwave, smaller quantity than a year old.....

I have a Maytag OTR Microwave, smaller quantity than a year old.. Right from the start, when I would cook something approaching a baked potato or a frozen dinner for longer than 4-5 minutes, the microwave would completely shut off. If I own a frozen dinner where the directions utter to cook for 4 minutes then stir, when it stops after 4 or 5 minutes, the mechanism turns off and I am stuck beside a half cooked dinner for close to 20 minutes until the microwave turns spinal column on.

I was still beneath warranty when a 'repair man' came out. He said he would enjoy to take the microwave to his place of work to fix it. But he finished up quitting on the job because he didn't want to uninstall it.
Another repair man come out and said it could be the sensors, but said if he replaced the sensors, it would work the same.. Basically, he didn't want to do the work. Nothing else turns past its sell-by date, electician said it wasn't a power outage thing.

The vent is installed properly, and I do depart from the fan on, but it still happen.
Mold contained by the Arctic?
it's not a thermal cutoff, those aren't resetable, unless you live at the north pole, they have to bring back to something like 20deg far to reset. If you have a faulty cooling aficionado it would kill the magnatron thermal cutoff. It sounds approaching it may be a control board issue.

I broke my wash contrivance?
It sounds resembling it is overheating. You may need to check to be sure adjectives the packing and wrapping material be properly removed when it was installed. Otherwise, it may enjoy a faulty cooling lover.

Stupid friends?
Answers:    It could be a few different things, possibly a faulty thermal cut-off on the magnetron, the magnetron itself or an intermittent position switch. Find a more experienced repairman. Good luck. P.S. a thermal fuse will not reset, but a cut-off will.
