It's usually a bad door switch or a broken door switch mount. Once in a while it's due to a board problem. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
SOURCE: would not heat, now outside gets hot
yes! , this is dangerous , be cause it sounds like the magnetron that sends out the microwaves may not be controlled , thus heating the outside and will be sending waves out of the microwave!
you will need a qualified electronic repair shop to deal with this, these microwaves are very dangerous and that unit should not be used untill it has been fixed , for the safety of you and anyone who uses or is around when in use.
these microwaves that are sent across the air to heat the food is burning it and it can do the same to you or any one who is around it while in use
even when in working normal conditions the waves still leak out some , so i always walk away when heating food in the microwave and i advise others to do the same
so the magnetron will need replaced and maybe another component but it needs to be tested to make sure nothing else is damaged also
hope my help has pleased you and that you can give me a fixya rating( all others hurt our rating) as i work on these and i know the symptoms that happen and the causes
again hope you can give me the fixya! , thanks , and if you need any other help, just ask me!
electech
est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.
Thediode
and capacitors can br tested. The capacitor must bealloweddischarge
before testing, or you risk to get electrocuted, evenifpower is off.
Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
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.

If it is working but not heating, then test the high voltage
capacitor,the rectifier diode.or the magnetron. If all this are fine,
test the control board.If turntable is not running check also the door
switch.
