    On an over the range model, you would need to pull it down from the wall, and once you got the cover off, you would probably need to remove a lot of screws to get to the magnetron.

    It may be very involved, but it's simple.

    Even simpler on a counter top model.

    But what makes you think it's bad? What symptoms are you having?

Viking vmos200 sparking

If there is spark please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is leaking and sparking to the ground. As you have mentioned it was stored, it is quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Now switch the microwave power on and use a cup of water to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. Replace with same type. If not check the waveguides within the cabin for food particles that can burn and spark, check for rust that can corrode and spark when the ceramic paint has worn out.
If there is heating without any issues, you can use the microwave safely

The noise filter is to block electrical noise, not auditory noise. "Noise" in electronics means any unwanted or unintended electrical signal.

The purpose of the noise filter is to help prevent any electrical noise generated in the wiring of the microwave from getting into your house wiring, which could cause interference with or disruption of other devices.

If your microwave is making auditory noise, then it may be a loose cover or panel, a rubber bumper fell off the high voltage transformer, or one of the components is failing.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the magnetron can be bad without that sound.

If either of those two were bad, it would not cook.

I smell burning odor when I turn it on, its a built-in Viking Model DMOC205SS Microwave.

From your description it is more than likely the magnetron is on the verge of failure, "heats food" I recommend having it checked before you use it again.

Our Viking VMOS200 just stopped working. The lights and the countdown timer work, but no fan noise and no turntable spin.

it has nothing to do with the magnetron. first you have to fix step one. then you will know if the magnetron is bad. its one or two of the primary switches on the bottom of the switch tower. usually with these mw if you dont press cancel to stop the mw, and you just push the latch to stop it, those wires heat up and cause the microswitches to burn and loose proper contacts.

put a cup of water in the mw. set it to one minute and as its counting down. push on the latch LIGHTLY, as to not fully open the door and you will hear the magnetron kick on and the turn table start to rotate

Microwave powers up but does not cook??

HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

VMOC205SS quit heating, it runs but does not heat? What part do I need?

the heating components of a microwave r the diode, magnetron, and transformer. checking a unit plugged in can be dangerous seeing there is about 5000 volts from the step up transformer. if you have a amp probe you can check the amps at the wires powering the transformer. if you have less than 12 amps, and 110 volts at primary side of transformer change the magnetron and diode

Microwave not heating food

It's most likely the Magnetron. The are not very easy to install and quite expensive. Older models magnetrons cost about 80 bucks from GE. It's probably not something you would want to try and repair yourself. Call a GE service person.

Magnetron replacement

On Certain conditions, they must have a basic knowledge of what they are doing, save your loved ones the cost of a funeral and buy a $50 print on microwave servicing to learn mainly how to discharge a high voltage capacitor, which store a dangerous amount of voltage. as long as the magnatron is of the same dimensions and vents, screws all go in the same way as well,certain models require the same value magnatron, some dont. Good Luck.
