Problem with Maytag microwave MMV5156AAw

This microwave was working fine until this morning. Its about 5 years old and this morning when we used it, it sounded different followed by some kind of burning smell. The food that was in it for heating didnt get heated at all. Any suggestions on what could have been wrong with it?

Thanks!

    Sounded different how? Louder? Quieter?

    It may be a shorted high voltage diode or a bad magnetron or high voltage diode.

    Please write back with more details.

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)

Typically, no heating of food, indicates a bad Magnetron (tube) or associated components. The oven can be repaired. Magnetrons are not hard to replace and can be ordered online through MCM electronics www.mcmelectronics .

However, due to the dangers of high-voltage within the unit, I would recommend taking the unit to a repair center.

Look in the manual to see what the warranty says. See if there is any information regarding the magnetron or parts. You may be able to get it repaired for free parts, less labor.

Please let me know if I can be of further assistance to you.

Good Luck,

- Jim

It's probably the magnetron or high voltage rectifier diode.

(When a capacitor fails, it will short, causing the fuse to blow. They rarely "open up")

Here are some links you or someone you know can use for test help, but read their safety warnings first:

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If the food in the cooking compartment is not heating at all, then you may have one of several components related to microwave energy generation that have failed or became disconnected internally.
Magnetron Tube, HV Capacitor, Filament Transformer or any number of sensors that disable power to the system. The control board could also cause the system to noty function correctly.. You wanted general inputs.. there ya go.. LOL
Not sure I told you anything you didn't already know but you should ask the tech what he did after he gets it going...

SOURCE: Stopped heating food

This is usually caused by either a bad door switch, a loose door switch mount (which are pretty simple problems to fix) or occasionally a problem on the control panel.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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

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

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you don't find yours, or if you want to look at it without disassembling the oven, you may be able to download it here.

If you only need a switch, you can order a universal type here for $5 postpaid.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

I have a 21y/o full sized Kenmore 700w microwave that I want to keep. Worked fine until this morning. Everything works except the heat.


Sadly Kenmore only offers parts for 10 years. The truth is a new microwave for 50 dollars will be much more energy efficient than your 21 yr. old model

That's usually a bad magnetron. This one has a 5-year warranty on the magnetron, so you should only have to pay for labor to get it replaced. I would call Maytag at 800-688-1120.
