SOURCE: my magic chef micro does not work. I replaced the

In many brands, there is 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.

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.

Some questions to help you or someone you know troubleshoot it:

When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

If not, then you probably have a bad door switch or door switch mount and should see these files:

http://www.microwavedisplay.com/safety.txt
http://www.microwavedisplay.com/disassembly.txt
http://www.microwavedisplay.com/doorsw.txt

If the inside light, cooling fan, and turntable are all coming on, then the problem is in the high voltage section, and then the next questions arise:

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

If there's no unusual noise, it may just be a bad connection at the magnetron.

Here are some links you or someone you know can use (in order given) for high voltage section test help, but read the safety warnings first:


http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)


http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)


http://www.gallawa.com/microtech/xformer.html

Accessing some parts may require you to pull the oven from the wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have

two people since the microwave can be heavy and awkward.

I have a magic chef microwave that heats well but when the door is closed it hums and get really hot on top while not in use. Eventually it will stop working all together until it cools down then I can...


This one actually sounds like the unit is cooking when the door is closed without blowing the fuse as it is supposed to do. Unplug it from the wall and let it cool down, which it probably already is. Put a cup of cold water in it, close the door and plug it in for one minute. Unplug it from the wall and check the water. Did it heat up? I'd bet that it heated the water up. Sometimes the cook relay sticks closed and it stays in cook mode. This condition is supposed to blow the fuse but really rarely it doesn't. I've only seen this happen 3 or 4 times out of about 14,000 units I have looked at in my career.
It would need a new control PCB and new door switches and probably a new magnetron.

Magic Chef MCO153UBF microwave


There are two things that come to mind, the magnetron is starting to fail, or the strapping has come loose on the fan motor housing, unplug microwave oven and remove top, [several screws] carefully inspect the fan for any loose mounts and tighten.

The problem will be a bad relay, a component that drives the relay, or a broken trace on the circuit board.

This blown trace happens a lot when the cooktop lights blow.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid in about a week with a one-year guarantee.

Feel free to contact me directly (and please remind me of your full model number) for more information & help or see our Web site.

The cooling fan is a must!

Otherwise, the magnetron will be ruined, and that drives up the repair cost.

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can order parts here: https://www.mcappliance.com/partorder.aspx
