My Samsung Microwave CM1929 is giving off a smell of burning (like plastic) when it is in use. It is heating the food ok. There was not an issue of something being melted in it, and it is clean. Can anyone help?

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.

SOURCE: burn at bottom of microwave

First try cleaning the burned mark off. Dip a scrubber in lemon juice and sprinkle salt on it; this is also great for burned coffee pots. The smell can be gotten rid of this way: Boil lemon peel in water, then put the water in a spray bottle. Not only will it make your microwave smell fresh but the lemon oil will make it easier to clean. If it still smells of burning rubber, take the back off and inspect the wiring. IF you see burned wiring, please do yourself a favor and replace the microwave!

Microwaves work by making the molecules in food get "excited"-they move more-meaning, if there IS rubber burning, then there will be minute molecules of rubber in your food, which is BAD for your immune system. If it's just burned chocolate, though, it is harmless unless you are allergic.

SOURCE: My Frigidaire over the stove microwave not heating food

Hi,It is most likely the magnetron and diode that has to be replaced. This job should be done by a tech, High voltage. Magnetron's normally have a five year warranty, check your owners manual.

SOURCE: I have a ge spacemaker XL1400. It was manufacture

it sounds to me like the magnetron is shot in it. this is the part that creates the heat. not worth repairing on a 10 year old unit. Sorry.

What to do when oven smells like burning plastic


new ovens do have a certian amount of "burn in" to do when there new best to heat up and cool off oven several times before actuall food use to remove any construction solvents and "cure" all the materials inside

also ck to make sure you removed all the shipping packing sometimes this gets left inside by accedent and smells something horrible when heated ( caution :: Foam degrades to cyanide deadly gas when heated!!!!)

Smoke and burning plastic smell in microwave oven


Burning plastic, not food? A component has overheated badly then, with a plastic case. The main suspect would be the high voltage capacitor in the magnetron supply. This is cheap and easily replaced ONLY IF you know what you are doing and can diagnose the fault. If you don't then DO NOT take the case off the unit as fatal voltages can be present inside even if the unit is unplugged.

I'd just buy another, as they are generally uneconomical to have repaired by a service tech.

Buzzing sound when you turn on .also smells like burning


The magnetron is failing, "heats food" and in some cases gives off a burning smell, "classic symptom" repairs will run close to a new microwave oven or more.

Is this oven still under warranty? If so, take advantage. If not, remove the power plug and the case. Short out, with a screwdriver, the large can-shaped capacitor with two terminals sticking out. Check the wiring and circuit board for signs of burning. If everything looks ok, remove the thin sheet metal wave guide that sits above or beside the microwave energy port into the cooking cavity. Under the sheet metal, there is a metal fan-like device called a 'stirrer' that has a plastic bearing. Remove this stirrer and smell the bearing. If it smells like the burning wire smell, replace the stirrer. You can buy it through 'Sears Parts' online.

Microwave turns, gives out strong burnt plastic smell, little (or no) heating


I would first suggest that you look inside the cooking cavity to see if your wavegudie cover is burned or carbonized. If so, it will need to be replaced. You can order one via Tritronics at http://www.wehaveparts.com The job of the waveguide cover is to protect the waveguide (opening) and the magnetron from buildup of food particles and grease. When the grease and food particles build up on and behind the cover, they will carbonize and arc - and maybe even flame up! The solution is to clean it and keep it clean - but if it's too dirty or is burned, it must be replaced. Sometimes it's necessary to remove the cover to clean both sides of it, and to clean the edges of the opening it covers. It is sometimes held in place with a small plastic rivet (or screw) and once that is removed, the cover will slide over a little then drop down. Be VERY careful not to get cut on the potentially sharp edges of the opening, and do not spray anything into the opening. Apply an alcohol-based cleaner (such as the purple kind) and /or gentle scouring powder to a cloth or paper towel and carefully wipe it out, then when it's dry, reinstall the cover and the rivet. I suggest to my customers that they NEVER use any ammonia-based cleaner (like the blue stuff) on a microwave, since the ammonia will crack and distort polycarbonate plastics. Once you remove and / or clean the cover and clean the opening of the waveguide, if it still won't heat and/or still has the smell, you may have a bad magnetron or high-voltage transformer. Feel free to post back if you still have trouble.
