Question about Maytag MMV4205 Microwave Oven
I was boiling pasta on the stove below the microwave, and cooking a microwave vegetable packet in the microwave and the microwave began emitting a loud continuous beep, but continued to cook the vegetable packet. The only way to turn off the beep was to pull the plug. When doing so, the beep disipated. Sounded like potentially a capacitor problem.
When I plug it back in the beep starts again, full force.
Is the microwave dead?

It could easily be a bad line fuse and/or line filter. To access you will need to unplug the unit and remove the outside case. Inside the unit, where the A/C power cord comes in, there should be a small circuit card (part #237068) located somewhere with a fuse mounted on it. This is your input line filter board with line fuse. Replace the fuse, first and see if this fixes your problem. This is a 20amp appliance fuse that you can purchase at any hardware store. Make sure you place the cover back on the unit BEFORE you plug it in. It is not safe to have this area of the microwave exposed with power applied. High potentials in the 4,000 volt range are present! If the fuse does not correct your problem, the circuit card runs about $26.00. Good luck and hope this fixes your problem.

Mmmm it's so easy,
First disconect the power, take the cover off, moslitly there would be 5 screws and two tab's on the top.
inside on the right hand side the magnetron it's a sylver box measuring about 4 in x 4 in x 5 in. It will have a plasic cover moslitly that would have to be remove first then on the magnetron there is 4 crews and one connector.
It should fall downard after.
If you have a power supply after the secondary , that may also be your problem.

Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

Your magnetron is overheating and tripping the thermostat, which interrupts power until it cools.
Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

the unit inside the microwave that heats called the "magnetron" has gone bad or the circuits that power the magnetron have failed. if its under warranty still, send it back to the manufacturer. if not you can call some repair shops and see how much it would be to service it, but its most likely going to be cheaper to purchace a new microwave since they are relatively cheap these days. microwaves are throw away product now days, they dont make them to last anymore, i hope this helps and good luck to you
