Maytag mmv4205baw died

Unit was completely dead. Family member may have turned on the unit instead of the timer for extended time. Replaced fuses and thermostat, and the exhaust fan has turned on, but door panel still dark, so I can't turn it off or anything else on. Light still out inside as well. Continuity checks on door fuses pass. I think I've reached the limits of my ability to diagnose!

It's almost certain that your magnetron has failed and/or thermostat which is mounted on it. Fist, unplug the oven from the pwer. Then open the door and remove the stirrer cover in the ceiling of the oven. Look for any dark brown burns, charred spots, or "rusty" looking areas. This would indicate that the waveguide has burned, which means the microwave needs to be disposed of. If it passes that test, I'd say the magnetron and/or thermostat area bad.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If you still have trouble, 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.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

It may be the fuse, or the magnetron thermostat (thermal cutout ./ TCO) or the oven cavity thermostat.

The first two can be accessed via the control panel opening, but if you need to check or replace the oven cavity thermostat, you will need to remove the oven form the wall.

Removing it from the wall is ideally a 2-person job and you should have your installation instructions handy. If not, you should be able to find it here.

Be sure to unplug the oven before you begin.

Maytag umc5200 microwave dies when oven runs too long


Sounds like it is overheating. Make sure you hear the blower fan running and If it is, you have another connection overheating inside the unit. Maybe at fuse or fuse holder??!!

My son ran the microwave (Maytag mmv4205aab) for several minutes (thinking he was running the timer). It now acts as if there is no power to the whole unit. I tried the breaker with no success. Shall I...


When it's run empty, that will cause the magnetron to overheat.

If it gets hot enough, the magnetron's thermostat will open.

Normally it should cool down and reset, turning the oven back on.

If not, the thermostat may have failed hard, and would have to be replaced.

The fuse may be bad (also or instead).

I had a fire in the microwave and now it doesn't turn on. Is there a reset button or do I have to go buy a new one? cbierke@gmail.com


It sounds like an internal fuse has blown. Unplug unit and carefully open the top cover to provide access to the A.C. power cord entry point. Hopefully the fuse is located in that area and is the older style 1/2" long glass or ceramic body with metal endcap on each end. ONLY REPLACE WITH A FUSE THAT HAS IDENTICAL ELECTRICAL RATINGS! After replacing the fuse and top cover reconnect the unit to the A.C. outlet and check to see if it is still dead. Still dead = repair shop time.

NOTE: Use a "fused" A.C. outlet strip (usually 6 outlets with circuit breaker) for your "after fuse replaced" testing. This gives you additional protection against accidentally tripping a breaker in your homes electrical panel.

Good Morning, My mother-in-law tunred the microwave on for 1 hour instead of using the timer. It now appers comletely dead. Anything we can do Or time to buy a new one?


Aounds like ***********-in-law cooked the magnetron. If a microwave runs for an extended period with nothing in it, the magnetron (thing that makes the microwaves) is likely to have failed.

Help the environment and don't throw it away, find your local Maytag service center, by using http://www.servicebench.com/servlet/WebSideServlet?Request_Id=APPWhirlpoolDealerLocateBrandedGoto&Request_Server=servicebenchpublic&Request_Brand=M&Request_ReadUrl=Y to locate your local agent.

It has completely gone dead, there is power coming to the unit. I believe I accidently turned the unit on to heat yesterday with nothing inside instead of turning on the timer thereby allowing the unit to...


You already know it can be a costly mistake. Had it happen in my own home!!!!

Several things can be wrong:

1. The Fuse inside the unit
2. The High Voltage Capacitor
3. The Power Diode
4. (bad news) The Magnetron.

There is an RF window that can be bad also as when a microwave is run with no load it can be burned. It is supposed to help protect the Magnetron from reverse flow RF and help disperse the RF inside the unit.

The next question is: "Are you going to talke this by yourself or have it repaired?" We can you advise on what to do but there are some hazards that you need to be aware of if your going top give it a go..... Just reply here. Thanks.

I have a Maytag mmv4205baw Microwave oven. It


the unit that creates the microwaves called the "magnetron" has gone bad, or the circuits powering the magnetron have gone bad. there really isnt a cheap way to fix it, and not a undangerous way to fix it yourself. if your really like the microwave and dont want to part with it, you can try finding a repair shop that will fix microwaves, but they will probably tell you it would be cheaper to buy a new one. sorry

Went completely dead


I would bet that instead of the kitchen timer's being on, the oven was running on high but empty for that forty minutes.

This would have led to overheating, which would have blown the thermostat on the magnetron.

Hopefully the thermostat did its job protecting the magnetron from damage, but 40 minutes running empty is pretty scary...

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.
