20 Most Recent Maytag MMV5207BAW Microwave Oven Questions & Answers

Possibly three parts. Take it apart and look for the broken one.

By hood light I assume that the light you want to replace shines from the bottom of the unit, not the light inside the microwave. If so check out he Disassembly video on this site: Maytag Microwave Light Bulb Not Working

you blew a circuit breaker...find fuse panel and reset breaker. It will be the one that is tripped

Microwave Oven Basic Troubleshooting Tips

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Sorry to read about your problem, I hope this helps you out.

Here are some issues you can have

1. Blown fuse in HV transformer primary circuit or HV fuse (if used).
2. Bad connections (particularly to magnetron filament).
3. Open thermal protector or thermal fuse.
4. Open HV capacitor, HV diode, HV transformer, or magnetron filament.
5. Shorted HV diode, HV capacitor (will blow a fuse), or magnetron.
6. Damaged protective VDR from filament to chassis (not commonly used).
7. Defective HV relay (not commonly use

Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances. Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged. A microwave radiation leakage test must be performed on the unit following any internal component repair.

Hi,

Please see the Wiring Information for Maytag MMV5000BAB Mwave in the pic #1 below.

There is a fuse in the diagram.

And in the secon pic #2 see the Internal Controls replacement parts for Maytag MMV5000BAB Mwave, Mounted Under Cabinet.

But I don't know how you find it in the cabinet. I hope the pictures help you to find it.

Kind Regards.

I would suspect the magnetron T.C.O., or possibly the bottom T.C.O. (not to be confused with the hood T.C.O.), the 20A ceramic fuse, or the cavity T.C.O.

We have the service / repair manuals for this model and have uploaded them to our site here and here to help you.

They will give you safety info, step by step help in disassembly, and troubleshooting tips.

Most computers will open these documents automatically, but you may need the free Adobe Reader.

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,

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

On my Microwave it saying e5 on it and it not reheating it self

Take it in for service. It is nothing that is straightforward, https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..

Hi,

You may even see the orange "glow plug" (called a hot surface igniter) glowing orange and so assume that it's OK. Not necessarily!! You have to measure the current/amp drawn by the igniter and compare it to this repair sheet before you can say it's OK or not. The gas valve has a bi-metal that open when a certain amount of current flows through it to heat it up. The igniter is wired in series with the gas valve. As the igniter gets older or weaker, it's resistance increases to the point where not enough current is flowing to the gas valve bimetal to open it up. As a result, the gas valve never opens up. BTW, a common symptom of the early stages of this problem is erratic temperature control in the oven due to delayed firing of the bake burner while cooking.

The hot surface igniter will not come on - check igniter with a ohm meter, you should have continuity through the glow bar, the glow bar can also crack = new igniter time. The glow bar comes on but the main burner will not light - you should have an amp probe to check properly, but often this is a hot surface igniter problem. The hot surface igniter often looses it's ability to get hot enough to open the gas safety valve. The safety valve can fail, but most times it is just a bad hot surface igniter. The hot surface igniter can also quit part way through cooking , in other words the oven may cycle a couple of times and then it just sits there with the red glow from the igniter. See this service sheet for the proper way and amp readings for the hot surface igniter system. Hot surface igniters do weaken and will eventually generate less heat than they normally could. When this happens they can still allow marginally correct current to flow to the oven gas valve for it to open but not get quite hot enough to ignite the gas burner immediately. When this happens, gas released into the oven can sometimes build up to the point where when finally ignited, the amount of gas lit can cause a small explosion inside the oven or cause an odor of gas with out the oven working. Yes, your glow bar igniter can glow orange-red and still be bad!! How a common gas valve works - click here.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Have you checked inside the microwave? Usually they have the manual hidden in there.

Replace the faulty door switch.

one of micro switch could be bad or the main board issue is there
