    My GE microwave is 1 1/2 hrs. old and it was very hot on the outside tonight after running it for about 15 minutes on high. I don't remember noticing that it has been hot before - is it okay or normal or should I stoop using it?

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!

SOURCE: microwave gets very hot on

If it gets hot enough were it is uncoftable to lay your hand on it then there is most likely a problem. If it is a new unit I beleive I would return it. Good luck.

SOURCE: Burning smell from Microwave

If you clean any appliances always plug out the unit power supply do spray any liquid in the unit that can enter inside the control, instead just wipe it with rug not spray. In this situation you have to call for a qualified technician. Maybe there are some wires that burned or rust in the control that cause the short circuit inside the unit..

With the symptoms you mention, I would suspect:

- loose or corroded connection at the magnetron
- bad magnetron
- shorted high voltage diode

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.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

SOURCE: Microwave heating problems

Many over-the-range microwave ovens suffer from intermittent problems caused by excessive moisture from the range/stove entering the microwave cabinet and collecting on the circuitry. Often the problem is with one or two simple connections that may need tightening or soldering. But, to repair these components, the microwave cabinet needs to be opened. So we recommend that you seek the assistance of a qualified appliance repair technician.

Why is the outside panel hot to the touch?

Many factors at play here. Are you cooking on the range? Are you using the microwave? Is the light on?
There is very little current going to the touchpad and if there were a short in it the touch pad would not work. It is just heat from another source. Don't worry about it.

My ifb microwave oven is getting hot outside while

Normally when u cook food in microwave the fod is cooked by microwaves, which means the heat is generated with in food. The temperature inside is never too hot and all the heat produced is absorbed with in the food.

On the other hand when the grill is switched on, a separate heatting element gets switched on. You can see this red hot element on the top side of inside of microwave. the heat from this element gets transferred to food through air circulation. But partof heat also gets transferred to the walls of microwave oven. This is the reason the wall feel hot during use of grill.

As i see ther is no problem with the microwave itself. Jut kep delicate thngs a bit away from the microwave.

Microwave heats outside too.

This is normal. However, if you are worried that your microwave is old and may be leaking radiation you may want to replace it, as they are actually under one hundred dollars for the most part; or you can get a little microwave radiation test kit at home depot or lowes for about twenty dollars.

Why is the paint bubbling inside microwave

The paint or inside in my microwave oven was bubbling up. I didn't think much of it until my husband came down with tongue cancer. He didn't smoke or drink. The only thing that was strange was the way my microwave was bubbling up inside. We were given very grim news, but in time and by swithcing hospitals, my husband is now ok and has been cancer free for 5 years. If ever my microwaves start blubbling up, I throw them out, it wasn't worth the health hazards.
