Microwave Shuts off...

Hey guys....our kitchenaid microwave will shut off automatically about 5 sec after pushing "add minute".....beeps with a morse code like pattern, then magically turns back on. Tonight....same thing happened, but instead of turning back on - the display showed a little man jumping around with the words "no main"..... I had to unplug for a few minutes - then it worked again when I plugged it back in. What's going on???

    microwave shows 2 small leds that cycle in downwards pattern - otherwise there is no display - when door is opened the oven light is off, then will turn on - buttons do not work. once door is shut, the microwave will turn on and the carosel will turn for approx 5 seconds - then shut off; it appears that when it does turn on that it generates no microwaves. I can not find manual - any thoughts?

It sounds like you may have a loose fuse holder or an intermittent part such as one of the thermostats, such as the one mounted on the magnetron.

One thing to try is to cook on the lowest power setting or defrost to see if it runs longer or fails more quickly.

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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should 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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

My GE stainless steel 1100 watt microwave starts beeping out of the blue and the display panel shuts off and when I open the door it resets itself and then starts to beep when I close the door again.


Try removing the power cord for about a minute, push all the touch pad 'buttons' and then plug it back in. If this doesn't work it sounds like you may have a bad door interlock switch or a bad PCM .. Good luck !

Microwave exaust fan starts on its own


There's a humidity sensor in this microwave oven that turns on the fan automatically if it senses an excess amount of humidity (steam from cooking for example) to possibly protect humidity or moisture from building up inside the unit.

Turns off after 3 sec


Usually this indicates failure of the magnetron and/or the inverter. Neither is easy to test without specialised HV equipment. Often the cause is operating the oven without anything in it. If this has happened, it will generally be failure of the magnetron.

Replacement of the magnetron is relatively easy (about 15 minutes) and the inverter a little longer but if you do not have the knowledge/skills please do not do it - there are very dangerous (deadly) voltages associated with magnetrons even after they have been switched off.

Cost of magnetrons ranges upwards from USD25 to USD100 (from Panasonic spare parts) and inverters range upwards from USD125. The cost of parts is often the reason microwave ovens are not repaired.

MICROWAVE CONTROL


The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.
