Question about Sharp R-1610 Microwave Oven

4 Answers

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

My microwave made some flashing and buzzing when I heated frozen sausage (only for 10 seconds then I stopped it), and then gave out strong burnt plastic smell. Now if I put a glass of water in it, it will turn and light up, but in a few seconds there will be strong plastic smell, and no heating as far as I can tell for that amount of time. What might be the problem with it? Is it self repairable? (Sharp R-161X overrange model) Thanks for the advice

    Thanks MicrowaveSvc,

    Ichecked and cleaned the waveguide according to you advice, however, the problem persists. I think I will try to heat a glass of water again when no others is at home to check if it still heats. In the case that it is the transformer problem, would the magnetron tube work?

    My problem is similiar in that I am getting a flashing and arcing coming from the cavity that is covered on the inside on the right side. It does not seem to happen on reheating of coffee or short 20-30 second jobs, but more when we do popcorn or bacon. We also get a burn smell and we are getting a burning pattern on the cover of the opening. If it is a replacement part, please let me know what part to try and whether it is better to have the authorized repair center perform it or it can be done at home by me.

    I have a GoldStar Microwave that is about 3 years old. It buzzed and arched and flames could be seen inside the upper right hand corner through the grate. I looked closer and could see a burnt component on the right side next to the right outer wall in the middle maybe two inches down from the top...attached to the side of what I believe is the transformer...(large brick of metal plates welded together). Every thing else looked fine inside. Would this microwave be worth fixing and if so - any idea what parts would cost?

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.

Over cooked something in microwave and now inside is yellow. How can I return it to white?


Once the plastic is yellowed, there's not much you can do to remove the yellow discoloration. Just continue to use your microwave as usual. If a burnt smell remains, you can heat vinegar in the microwave which will help eliminate the horrible odor--like burnt popcorn!!!! Yuck!

When a microwave gets a strong smell and then just stops working actually this means that something is bunt down in it, more of so the strong smell indicates that the HT (high tension transformer) inside has its windings burnt. If replaced check that while its on, its vent holes on the sides or at the back is not blocked, this helps it not over heat. Also check that the fan inside is working or else replace it too.

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.

I have Danby microwave, the food does not heat and there is smells like some thing is burnt. I have opened it and the high voltage transformer does not look burnt.


What is happening is that the magnetron is shorted, causing the high voltage transformer to overheat. That is what you are smelling is the insulation getting hot. When the magnetron shorts out, it makes a loud buzzing sound. Replacement magnetrons costs almost as much as a new oven so it rarely makes sense to fix.

Ge microwave jvm160wj01 was working and suddenly started buzzing, gave bad electric/burnt smell and buzzes. Still buzzes and does not seem to heat now.


Sounds like the magnetron just shorted out. Its the part the generates the microwaves that heat the food. Buzzing sounds are a symptom of a shorted mag. Usually not worth fixing since the magnetron costs almost as much as a new oven. Sorry.

Microwave not heating and giving burnt plastic smell


STOP USING IT!! UNPLUG IT!! Microwaves are inexpensive now. It will cost you more than a new one costs, to get it fixed.

GE microwv-doesn't heat, strong electrical smell, all else ok


The most common problem would be your magnetron. Check your purchase date, magnetron's usually have a five year warranty. Not a part I recomend trying to fix yourself (high voltage ).

Buzz, plastic smell and no heat


Chances are you have a magnetron that's failing. GE had a rash of "underperforming" magnetrons on these units. They replace the magnetron, stirrer and high-voltage diode at no charge for parts as long as a GE-authorized service center does the work. Sometimes the unit gets run too long in a failing state and the waveguide and chassis of the oven get damaged. The bulletin shows you where tyo check. To see if yours is covered, see this bulletin: http://www.microwavedisplay.com/ge_mw_mag_kit_bulletin.pdf Otherwise, you need to contact GE Customer Relations at 1-800-386-1215 as soon as possible and tell them your problem and they will put you in touch with a local authorized servicer.
