There is an internal cooling fan. Sounds like your s has failed and its thermal cut out is turning it off. Take it for professional repair. You can't open microwaves as they have special security screws, plus there is high voltage and dangerous compounds plus the radiation itself.

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.

you have one of three problems (H.V. diode shorted or leaky, H.V.capicitor shorted, or the magnrtron tube is beginning to draw excessive current)if thats the case its not usually worth spending that for the mag.,the other two items aren't that expensive

There are typically 2 fans in these units. The fan that cools the magnetron and then the vent fan that intakes from the top of your stove then vents the air out or away from the unit. Are the lights that shine on the top of the stove working?? Sometimes if a bulb blows violently it can blow a trace off of the back of the main circuit board and that trace may also supply power to the fan

take it to an appliance repair shop for a proper diagnosis and quote

Sounds like it is ready for the dump!
Without anymore information and diagnostics, it is not possible to diagnose further.

Sounds like the magnetron is over heating. Try putting a 4 0z cup of water in the oven along side the popcorn bag. See if this helps. Usually, the oven only runs 2 to 2.5 minutes for a bag of popcorn. You may have to experiment with the slightly different cooking time...

Sounds like a bad magnetron, i would replace the magnetron, Capacitor and Diode at the mag assembly, to be honest it will cost you more to fix than a new one.............

The plug should be located in the small cabinet above the stove. Leave it unpluged at least for 10 minutes. Mine does it occasionally when it gets hot. I haven't had a problem since I turn the fan on when I run it.

The problem is in the magnetron the heart of the system, or the inverter board, if microwave oven is 7 years old or less.

check fuses

Magic Chef... | Answered on May 09, 2014


A microwave can be dead for many reasons.

It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

I have a Magic Chef Microwave Model MC0153UB that is shutting itself off while cooking. I noticed before this, the light under the microwave blew during a storm. Do you have any suggestions?
