Magic Chef Microwave light will not turn off. MCO153UB

Today my Magic Chef over-the-range microwave oven's light (to light range area) came on by itself and will not turn off. I am not quite sure how long it was on before I saw it, but I could smell a scent like plastic or something burning coming from the unit. When I press the light button the brightness of the light changes, depending on whether it is "on" or "night" but when I press it a third time for "off" it does not turn off. it is not long before the burning smell returns so I have to unplug it and only plug it in to use it. Is this a simple fix or should we replace the microwave? It seems like a fire hazard. Thank you very much!

The turn table and fan are connected in series with the bulb,as you have mentioned that you have replaced bulb,so please check again for any loose contact on bulb holder or bulb continuity again.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Please reply back here and let us know if the hard reset doesn't fix it.

It may have a bad door switch, and we can help you check into that. The first test for that is to try it while gently lifting up and then while gently pushing down on the door.

Have you tried unplugging it than reapplying power ? Sometimes a power up reset will clear the logic on the control card and yes.. if it continues to run ...you have a potential fire hazard...

SOURCE: Changing light bulb in microwave oven

If there's no obvious removable cover over the bulb (and the owner's manual doesn't address it) some disassembly may be required.

Always unplug a microwave before removing or installing any bulbs.

The screws you need to remove should be pretty obvious, but a special driver (such as a T20H type or GTXH20-100) may be needed.

Be sure to put all the screws back in the right holes, since some may be special grounding screws.

Bulbs can be had in most grocery stores, hardware stores, home improvement centers, and big box or department stores.

Many models use halogen lamps. You must not touch the new one with your bare skin, as the oils will shorten the bulb life.

I was making popcorn and the microwave just died


Since it's less than one year old, it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

Vent fan high comes on automatically with cooking


Right, that would be MCO10UW and the owner's manual is here.

The owner's manual does say this, of course,

"To prevent overheating from taking place, the exhaust
fan is designed to automatically turn on at a low speed if
excessive temperatures occur. Should this happen, the
fan cannot be manually turned off, but it will
automatically turn off when the internal parts have
cooled. The fan may stay on for up to an hour after the
range and microwave oven controls have been turned
off."

That;'s standard on microwaves.

But these models do have a separate internal cooling fan (which should run any time you microwave) plus the hood vent exhaust fan, which should only run when you select it, or if there is an excessive stovetop or under-hood temperature.

So if it comes on whenever you microwave, that is incorrect.

When that happens, it's usually a defective vent thermal switch (a.k.a. hood TCO).

But since it's brand new, I would certainly contact Magic Chef about this. If it's in need of repair, they will fix it free, assuming the oven wasn't physically damaged.

Magic Chef Over the Range, MicroOven, model MCO153UBF


I tried the usual things, then checked the outlet in the cupboard where the unit is plugged in.....It was okay, but then I noticed a separate electrical cable going into the wall at the outlet. I went to the breaker box downstairs, found a breaker marked "Microwave Oven", flicked it off and on and away the microwave oven went....It is now okay. I guess the thermostat had turned everything off when it became too hot....
anyway all okay now....thx Janet
