If your microwave oven isn't working very well in terms of heating food.. and you have a burning smell coming from it.. there is a good chance that the Magnetron tube has failed or is close to failing or the transformer that feeds it is failing.. The cost to repair may be higher than the cost to replace the entire Microwave so I would suggest you just consider purchasing another one.. Just my opinion.. Hope that helps...

7 yr old unit emitting burning smell. Everything still works. Is it worth trying to get repaired or just buy a new one.


is the burning smell just when you use the convection oven or when you use the microwave , reason I ask is that if its only coming from the convection oven then chances are you have something melted on the heat elements , this can be cleaned off with a dry brillo pad

I have a R-8520 Sharp carosel microwave. Previously the convection stopped working, now it does work but heats up too much to the extent that fumes come out from the back of the microwave and it smells of...


I think it might be a good idea to consider having the appliance replaced, the unit is a fire hazard and judging by the burning smell it is on the way out.

My Kenmore 721.626222 which I have had about 6 years, runs but does not heat. There is also a strange smell - something like a burning smell.


When the oven does not heat, the problem is usually due to the magnetron failing. It the part that generates the microwaves that heat the food. It fails by shorting out causing a loud buzzing noise. The burning smell is the being magnetron overloaded due to the short. It not worth fixing since the replacement cost of a magnetron is close to the price of a new oven. Sorry.

Panasonic NN-CT776SBPQ, just 2 y old, burning smell advise what could be the problem and how much it cost\r\n


check if the smell is coming from within the cabin. If so due to non usage of food covers some food particles ccould have got stuck while on heat to the sides of the cavity and results in heating and smoking. If so clean well with a dry clot and wipe out any moisture on the magnetron fitting slot.
However if the smell continues, check the capacitor to the magnetron or the magnetron or the main transformer itself.
You must open the cover and check for the origin of the smell.
estimate cost and decide.
Creddit if the advice helps.

Daewoo kor-861h, electrical smell and will not heat.


Turn if off, and leave it alone, remove it, if you can remove the unit, take it in for service, something is wrong if you smell electrical, most people for some reason can smell and identify correctly electrical or at least insulation burning smells, which means something is burning internally, not safe, fire hazard, unit needs to be repaired by qualified technician or replaced with new unit, take no chances, nothing you can do to repair this, could be a shorting transformer, or shorting power cables, but to attempt to trouble shoot this with email is a long shot, and depends on your experience expertize and testing equipment.

I wish I could give you a short easy answer, but the hazard and your safety is more important than a microwave.

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.
