That would be a problem with the secondary interlock switch (bottom door switch) or its mount.

I would refer you back to the links in my clarification request above.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

My microwave has stopped working. Everything functions properly, including the light when the door is open, and the timer countdown begins when I press start, but the actual unit will not turn on...


Sounds like a bad magnatron (the part that emits microwave energy) or maybe just a bad door switch. If the door switch is bad it won't let the unit come on.

Microwave timer works but will motor will not run/cook.


If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.

Mbbs 01 thermador micro oven: timer counts down, lights go on, but no heat, no fan and turntable does not turn. is it a fuse?


Key clue is table does not move---All microwaves with a table have a lever switch that is engaged when door closes--only can get at from inside the unit----it prevents the unit from operation if door not closed.

What happens from closing door a lot is the switch with a lever arm can come loose or even if snapped into a plastic holder break out of the holder.

IF this it is not too expensive a repair.

Microwave has power, but nothing works.


The door switches are more than likely the problem, one or two will need to be replaced, I recommend a professional.

I cannot stop the DEMO


Demo Mode The Demo Mode is ideal for learning how to use the microwave oven. When set, functions can be entered without actually turning on the magnetron. The microwave oven light will come on, the fan will run, the countdown will run very quickly in the display, and the turntable will rotate. To Turn On/Off: The microwave oven and Timer must be off. Touch and hold TIMER SET/OFF for 5 seconds until 1 tone sounds. Repeat to turn off.

Turntable turns intermittently so unit will not operate


The turntable fan and light all share the same feed, first check wiring for loose connections the problem though is most likely with the controller

Turntable and cooking power not working, everything else does.


You have a shorting membrane keypad.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

Feel free to contact me directly (and please include your full model number from the tag in or on the unit) for a free estimate and free tips & do-it-yourself advice.

Whirlpool MH1140XM: has power, but no heat, turntable not spin.


Test the high voltage capacitor, the rectifier diode.or the magnetron.

The diode and capacitors can br tested. The capacitor must be allowed discharge before testing, or you risk to get electrocuted, even if power is off. Capacitors can get discharged by shorting their two contacts.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.

All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

Fan & Turntable start when door is opened.


sounds like there is a switch that is bad. you can go buy a new MW for about 200$ and in yours if there is a major problem then i would just go buy a new one but might be worth a repair man to come check it out


pleas do not poke around in the microwave as it carries a charge of 5000volts and can kill you even if not plugged in DON'T TOUCH THE WIRES WITH BRAIDS ON THE OUT SIDE if you must get inside of the unit

Microwave turntable won't turn


You may have a tunrtable motor or spindle problem..
This info is from GE website..( link : http://genet.geappliances.com/geasearch/Dispatcher?REQUEST=GETSEARCHRESULT

To minimize the possibility of electric shock, unplug this appliance from the power supply before attempting any maintenance or cleaning.
  • Make sure the turntable is centered and seated properly. On models with a stirrer motor there is a shaft protruding up through the floor of the microwave. Make sure the turntable is securely fastened to this shaft. On models that turn on a ring with wheels attached, make sure the turntable is seated securely on the ring.
  • Check the turntable to make sure it is placed right side up. If the turntable plate is upside down it will drag on the floor of the microwave.
  • Check to make sure that there is no food or debris under the "wheels" of the turntable ring. Food can prevent the wheels from moving forward.
  • Be certain you are pressing a cook function rather than a timer function.
  • If the microwave has a turntable on/off feature make sure the turntable was not inadvertently turned off. Try depressing the turntable on/off pad to re-engage the turntable.
