Maytag MMV1153BAW There is an interior access panel inside the microwave. It is a round plastic panel with type (OPEN, CLOSE) arrows that tells you which direction to turn the panel to open it. There is a small plastic tab (about the size of a thumbtack) that holds or locks the panel in place. That small tab broke and I've fixed it temporarily (until I get a new plastic tab). What is the purpose of the device (a round metallic disk looking thing that apparently rotates) inside the panel? When I put it back together a spark arched out of that panel, but then everything seemed fine. I'd like to know what it does and if I should stop using the microwave for now. The MW seems to be working just fine. Thank you. DPN

Hi,

Either the latch in door (spring related) is not in the correct location or you have a door switch issue and its not expensive to fix if you husband is handy. Part number you can use is 28QBP0495 or the factory one 3405-001034 (more expensive). This issue is common and these switches are located inside the control panel on the left side, the switch you seek is the lowest one in the bracket of three. Good Luck and I hope this helps.

I would suspect the power control board which is item #2 on the diagram.

Hi,
Here is a tip that will help you to figure out what is wrong with yourMicrowave Oven....

Microwave Oven Basic Troubleshooting Tips

There are three micro switches inside the latch assembly. One of these absolutely prevents the possibility of the Magnetron being energized while the door is open. The way it works is if the door is open and the Magnetron is energized, it will act as a direct short circuit and that will blow the fuse. It works very well, unfortunately, that tremendous surge of current ruins the microswitch. Replace the switch. You will find this same information on the instruction sheet inside the cabinet.

There is always a fuse inside a microwave.Sometime this has only blown due to a surge,and upon replacing, the microwave will continue working.If it is something worse the fuse will continue to blow.In this case it could very well be the transformer,but there are other possible causes as well.(for example the control board or a short.)

No... you are not in a microwave induced time warp...
Your microwave oven needs a "reboot". The same thing happened to me.
Unplug your microwave oven, wait about a minute (more or less), plug it back in. Try setting/running your kitchen timer, boil water, etc. Your timer software on the microwave should be reset.

the fuses for microwaves are not normally placed on the control panel...they are in the back near the power cord...but the fact that it beeps 3 times means the fuse is ok...power is going in....most likely, the fault is one or more of the door interlock switches which arc every time you open and close the door and they corrode or wear down very badly sometimes even burn away so that there is no more contacts to come together....interlocks are cheap to buy and they just snap in place....access to them is easy...just remove the cover and look right behind where the door closes on the inside, you'll see a plastic bar on the door that when you close the door...it pushes on the interlock switches on the inside to activate the oven.......if the interlocks are ok...then you probably have a shorted magnetron....very common on any type of microwaves are these 2 parts...( the interlock switches and /or magnetrons.....it's not likely that your control panel is bad unless you physically see that something has burned on it.....good luck

This is the stirrer cover. It is important. It is to keep food particles and grease out of the stirrer and waveguide area.

If grease or food particles build up, they can arc, which will cause burn damage to the cover, stirrer, chassis, and/or magnetron.

If you have any arcing, you should remove it for cleaning. Be careful of sharp edges.

The stirrer's job is to stir the microwaves to ensure even heating, even when a turntable is not present or not used.

My microwave was totally dead. Things I discovered: 1) There is an easily replacable fuse accessed by taking off the top front vent cover (two screws on top, gently massage off) and then the inside plastic grill. UNPLUG before doing this! 2) Pop off two wires on either end of fuse holder for safety. Then pop out fuse and replace. For more extensive help, there is an evelope with a wiring diagram inside the case on the inside wall! Very helpful when diagnosing the surface lamp problem (I forgot to plug the ballast back in when I closed up the bottom).

The 5-digit number above is not a complete model number.

If you can post the full model number I can probably give you a link to the explode view, or you can find it here: http://www3.sears.com (the 3 is correct)

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to 110V connectors, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb.

In many over-the-range models, that can mean having to take the oven down from the wall! For safety's sake, that should be a two-person job and it's really helpful if you have your original installation instructions to do this.

Many models use one halogen lamp to illuminate the cooktop and another to illuminate the cavity. You must not touch them with your bare skin as the oils will shorten the bulb life.
