My MAGIC CHEF MCO153uw stopped working. It heats up and then stops and the entire unit goes totally off no power nothing. Then it turns on by itself a while later. It will heat up for 2 or three minutes with no turning of the plate. the plate turning is totally not working. Is it time to get a new one?
Thanks

This sounds like a thermal protector is turning the microwave off. If I were to hazard a guess, it would be the magnetron (produces the microwaves) is overheating causing the shutdown. If the fan was not running it would create the same condition by causing the magnetron to overheat.

It has a fuse inside. Check the door switches while you're in there. The one in series with the fuse can weld in the "on" condition and blow the fuse and/or the circuit breaker.

Magnatron is suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing either the magnatron or the high-voltage capacitor and diode. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
