I have a maytag model mmv1164ws when you turn it on makes a buzzing and smells like something burning!

Good Afternoon Friend,

I understand that you are receiving a burning rubber smell from your Frigidaire microwave. I also see that your appliance will run for a couple of seconds, and then you hear a weird noise, followed by a burning rubber smell. I suggest contacting your local authorized technician, especially when dealing with your microwave. They will be able to diagnose your appliance and determine what is causing that sound as well as the burning rubber smell. Hope this is helpful.

This indicates the magnetron has failed, buzzing sound and odor are classic symptoms. It is cheaper to replace than have it repaired.

The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

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.

Two weeks? This is a warranty problem. The buzzing noise was probably either from high-voltage arcing or an overloaded transformer trying to drive a shorted component. The smell is from something electrical getting fried. Remember it; the next time you smell it, you'll know to pull the plug.

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

the magnetron the unit has gone bad.sometimes there is burning smell as u mentioned.it is little expensive repair arond $ 150.00.find out the price of new unit plus iistallation/delivery chg and then make a decision.

The symptoms you are describing are typical of a magnetron that has gone bad. Continuing to attempt to use the oven in its current condition can cause further damage. So, I would recommend not using it. Microwave ovens are considered dangerous and repairs should not be attempted by anyone that is not electronic saavy. The High Voltage Network inside the oven has voltage potentials of 14,000 volts and higher. If you feel this is something you wish to attempt, the Magnetron part number is 1156751 and costs approx. $158. Keep in mind, if the magnetron has been arcing and making a burning smell you may have burned the protective coating that lines the walls of the waveguide. If the waveguide is damaged it is not repairable. I do not know if this is a replaceable item on your model microwave. Double check your warranty information and/or owner's manual. In many cases the magnetron is warranted for several years beyond the limited warranty that comes with most appliances. Post back with comments and let me know if you want me to assist you further. In addition, if you provide me with your EXACT model number (located along the door opening) I can narrow down parts a little better. I know this all sounds discouraging, but I do hope I have been able to help you.
