Microwave Model #JVM1630, turns on runs with slightly different sound, bad smell no heat!

Possible bad mag or bad connections at mag or capacitor. If the turntable is turning the control circuits are working. Will be problem in High Voltage section. Is it making any kind of grumbling sounds or any bad smell??? If so Probably bad magnetron.

The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts (including a fuse and the diodes), then most likely the magnetron is done and a new microwave is the way to go.

Let me know how this works out for you.

Hi,
Here is a tip that will help you to figure out what is wrong with yourMicrowave Oven....

Sounds like the magnetron bit the dust.

No, not with the same mounting hardware. You have to replace everything. I recommend Panasonic first if you can find it in a hanging hood model, Whirlpool second. Make sure you also install a 2000 joule or larger surge protector. Good Luck, Appliance Specialists

Microwave will not heat during operation

Possible bad heating element, You should remove the cover of the unit and look at the heating element with the power off. Until you get your problem resolved I would recommend not to even turn it on due to the fact that you are unsure what is going on and you smelt some burnt smell. Just for safety until you fine the problem

A burning smell along with a different sound (growl) USUALLY indicates a breakdown in the High Voltage Side. This is not a direct short (short circuit) or the line fuse would have blown shutting everything down. The High Voltage Side is made up of-- The Secondary ,or High Voltage Side of The High Voltage Transformer, A High Voltage Diode, A High Voltage Capacitor, and The Magnetron. If The High Voltage Transformer is the problem it will smell like a florescent light ballast burning, and will smell each time you turn on the MW. A HV Diode burns and opens, thus no more smell. A HV Capacitor usually does not burn nor does the Magnetron. There is no Cheap-Fix unless you can see that the HV Diode is burned into and you can get to it to replace. CAUTION: Always unplug from power before attempting to repair. NOTE: If you replace a Diode make sure it goes back in the same direction it came out. Yes there is a front and back.

I would check the area around the ceiling of the microwave. There may be grease of other food buildup on the waveguide cover. Or the stirrer may be sticking or arcing, which would need to be replaced. This unit may be subject to post-manufacturing modifications, requiring a few new parts. You might check on this with GE Customer Relations at 1-800-386-1215 (8-6 ET). If they cover the cost of parts, great. If not, you can get them cheaper here: http://tinyurl.com/gv383 Feel free to see my site for my safety & disassembly files.
