Question about Maytag MMV5207A Microwave Oven

1 Answer

Blowing fuses The mwave is 2 months old. We just installed it a new Kitchen. We used this mwave about 2 weeks. The wife said it quit. I opened and checked and one of the 2 fuses blew. I replaced the fuse and it made a loud hum and blew the fuse again. Control panel and lights work ok untill fuse blows. I have been waiting 2 weeks for Maytag to get me service that doesnt seem to exist. Do you suspect t he diode or something else? Thank you

    Is it a model MMV5207A as it's posted under?

    Which fuse blew? I only see one in that model.

    When does it blow?

    If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

    If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

    If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

    The high voltage diode won't make the fuse blow.

    Once I get more details, I may be able to narrow it down (for academic purposes, of course) but any unauthorized repair attempt will void the warranty.

    I hope they get the servicer out soon for you but feel free to clarify here.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

You can usually find helpful exploded view diagrams and order parts 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.

But I would wait until the authorized servicer gets there (or take it to them) to maintain your warranty.

We're happy to help and we appreciate your thoughtful rating of our answer.

6 year old Panasonic 1250W High Power Inverter Microwave Oven (Model NN-S954WF) Manufactured May 2004 has completely died. Wondering what might be the problem and is it fixable or should we just get a...

These early inverter microwaves blew their high current power transistors quite regularly. These high current power transistors are quite expensive to replace, and if one blows, there is a likelyhood of others blowing. As the microwave is over 13 years old, I'd suggest getting a new one. Inverter technology in microwaves is now a mature technology, resulting in reasonable prices and much improved reliability.

While in use my microwave shut off and stopped working. Could it be a fuse? If it is a fuse where would it be located.

mwaves shut off when they overheat and take a time to recover. This is a failsafe to prevent fire.make sure the unit has plenty of airflow around it and the vents are not blocked off ( hutches are notorious for overheating Mwaves) Sometimes the steam from a potato or a cup of water will overheat the sensor and cause it to shut down.

If it is a fuse the whole outer case hasd to be removed and it's usua;;y top left or right on the inner pod.

No power no lights

There is a fuse inside of it near the power supply usually around the electrical cord, and it might have blown out if the outlet you plugged it into was not properly grounded.

My microwave XL1800 keeps blowing fuses

Now this is not quite clear enough to give an accurate single answer.

Is it the fuse within the microwave or the general house supply fuse that blows?

If its the latter then an electrician needs to create a separate fuse line to reduce the overall load on the fuse, 15amps generally. Many houses have too many plugs being used at once on the same circuit TV, dishwasher, fridge/freezer, electric jug etc all drawing power. Big screen Tv's are the worst offenders.

If it is the fuse within the Mwave, then it needs attention,as a short has developed in the unit and needs to be corrected.

I will assume it is less likely to be this and punt for the first solution ( House fuse box overload)

Im looking for fuse replacement, where can i buy one ty

Fuses for Microwaves SHOULD be available from most reasonable size electrical stores. I suggest you open the Mwave first and remove the old one as a sample as many are not straight glass fuses but block ceramic ones usually around 25-30 amps.

2 year old ge profile spacemaker Microwave lost all power

Inside unit is a cylinder fuse which can blow for a number of reasons. External cover needs to be removed to access. If you are confident in doing this and can find & check the fuse then it would be my first guess. If fuse is OK then you will need to have repaired. If fuse isblown & you replace then it blows again,you will need to have repaired. regards
