I have a 7 yr old GE over-the-stove microwave and have recently noticed an odor. It doesn't smell like the typical electrical burning smell. In fact to me it's more of a sweet smell, kind of like maple. I had cooked some bacon the night before noticing this smell and I'm wondering if it could be that. It was a hickory smoked bacon if that makes a difference. I just don't want to dump the microwave if there's no reason to, nor do I want to buy a new one if I don't have to. Thanks
SOURCE: burning odor, no heat
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.
