Question about Magic Chef CMV1000B Microwave Oven

1 Answer

Micro looses all power during cooking, power returns after a few

My Magic Chef MCO160UW intermittently shuts off during cooking. It is often with popcorn, but has happened with other foods. It's still under warrranty, but MC says this "underload condition" is normal and says I need to put a cup with a few ounces of water in with the food. The unit worked fine without this problem for about 6 months, but now it seems to be getting progressively more common. Also, I've owned micro's since they first came out and have never encountered this problem. Is there a probable defective thermal overload protection, or is this indeed a normal condition? Thanks in advance!!

This is a defect. RERURN it while it is still under warranty. Tell the counter person you need to speak to his/her supervisor if they give you that song and dance again. Threaten to file a complaint with the better business bureau and with your state's attorney general. Be firm but polite and insist that they honor the warranty.

Have a magic chef mco160uw microwave. Had a recent


No! there is no reset, the power surge has more than likely damaged the keypad controller, and on the back is a circuit board that has the microprocessor with additional components that controls the vital areas of the microwave oven. If that is gone, it is cheaper to replace than to repair.

Magic chef mco160uw Tray not turning and light off


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.

Shuts down for 5 minutes


I have the same problem with my new magic cheff over the stove microwave oven. I call magic chef and they gave me the 800 number for the service center (1-800-775-0202). When I described the problem they told me to just put a plate under the popper and this wouldn't happen anymore. I haven't tried it yet but here's hoping.

Replacing the fuse of a MCO160UW


A microwave can be dead for many reasons.

It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

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 (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

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

There may 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.

Oven turns off


Hi,

You are running the risk of damaging the Magnatron by doing this.

Check the packets you are using, you will have to reduce your power output.

This is because microwaves act by being absorbed by water. There is very little in popcorn and in fat. Once this has been evaporated, the microwave energy builds up (as it is still being produced - but not absorbed), and ends up cooking the magnatron itself.

I have seen countless posts on here after cooking popcorn!

More fun on the hob anyway - and cheaper to buy in bulk!

The cooling fan is a must!

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

It sounds like the magnetron is overheating and the magnetron-mounted thermostat is tripping.

This can happen if the internal cooling fan is not running - do you feel air strongly coming out the back or other vent?

If it has grease or other filters, be sure they are clean and not blocked.

Otherwise, the magnetron may be failing. Please post back once you've looked this over if you need more help.
