Hi,

That is the Magnatron or the Hi-Voltage transformer. If I could smell it I could tell the difference. The transformer will produce smoke more so than the Magnatron.

Check those two one will need to be replaced.

But if you can do the checking your self, you can call some repairer around your area to check it out for you in other to prevent further damage.


Take care.

MIcrowave emits an electrical smell while cooking. It still cooks, but has started emitting an odor recently when in use.


Is the smell ionized (the outside smell of a cold winter morning air) or more of an electronic component burning??? if it's more of an ionized smell it could be normal, (if the smell is strong) it could be a leaking high voltage cable (electric arching) bad insulator, if it's more of an electronic component burning smell, it could be a overheating component, in both cases you should have it checked by a professional technician...

Heard a pop and then an electrical smell. Unit is working but a faint electrical smell occurs each time unit used. Should I continue using it? It is built in with a trim kit.


No that is a very dangerous situation. What is sounds like is you had a short that blew apart but not completely damaging the wires. You should unplug, and open it if its out of warranty and inspect the wires. If the wires are partially burned it can heat up and cause an electrical fire.

Smells like burnt wires


It is very possible it may have burnt wire or burnt capacitor. Remove unit, remove top cover and look inside to see if you see any burn marks or burnt wires. Also check fuse to see if it is good or not.

Last night my wife accidently turned on the microwave with nothing inside. It probably ran for 15-20 minutes before I noticed a burning smell (burnt wiring) After opening the door I noticed the unit had no...


well I can tell you roughly what happened. You overheated the oven, as there was nothing inside to absorb the radiation. So the sensor shout off the power ( safety switch) It returns when the oven reduces in temperature. The burning may be due to internal damage to some of the insulation compound. It takes foreverf to get rid of smells from microwaves no matter what you use including vanill or some other anti stink medicine. The unit is probably OK but overtime will now begin to deteriorate and may even leak radiation to greater extent.

Dump it is my suggestion, but make sure it is damaged sufficiently to prevent dump rats from salvaging it and using it.

The unusual noise ( almost missed that) is damage to the rotation motor bearins that have been expanded and are now out of alignment.

Too risky!

My GE spacemaker microwave won't heat and makes an unusual sound


I have the same problem on my oven- model JVM1640WB and called an appliance repairman who is honest and reliable (I've used him before). He said the problem is with the electrode, to fix it is roughly $300. He recommended buying a new microwave rather than fixing it.
