Magic Chef microwave MCO160UW stopped working after trying to change the lightbulb.


First thing to do is unplug it and take a pair of needle nose pliers and get the base of the old bulb out and replace it. Microwave ovens have a lot of things wired in 'series' which means that is one switch,bulb or any thing else in the circuit goes out then the circuit cannot complete it's path and will not let the other parts function. It is a safety feature that is built into them. As in many things I think they over do the safety features but they didn't ask me when they built it. LOL! Try replacing the bulb and let me know how it works.

The display screen on my Kenmore Elite Microwave model #721.80802400 has frozen on 13 seconds! does not respond to turning or pushing dial. Only works by pushing manual. No idea about cook times. Is this...


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

If it still doesn't work, it may be a controller issue which can be repaired.

My panasonic inverter microwave model no NN-T523M switchs off after 5 secondsno matter what setting. the digital screen says consult manual, which has been misplaced


You can find Panasonic owner's manuals here.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

See if this describes what's happening:
  • Put in time, push start and unit runs for 2 seconds, relay clicks, unit goes off. Cook time on display goes off and clock time comes back. Bad upper interlock switch and charred connector
If so, see http://207.234.249.73/mwd/safety.txt http://207.234.249.73/mwd/disassembly.txt http://207.234.249.73/mwd/doorsw.txt

Otherwise, if the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

If it stops after 7 seconds, it has a problem with the inverter.

It may be a loose connection in the wiring between the inverter, magnetron, and/or control board, or maybe one of those components has failed.


Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

You can find an authorized Panasonic servicer here.

In Canada, you can find an authorized Panasonic servicer here.

If you decide to replace your inverter, you can order Panasonic parts from Encompass here or you can call them toll-free at 866-779-5835.

Buttons don't work


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Otherwise, you may have a failed membrane keypad.

If you still need help, please post a new help request to FixYa and include your brand name and full model number.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

Sharp microwave 1200 watts keypad showing


Not a complete answer, but may help describe problem: Our R-510B should be the same except for color, and for several years it has intermittently messed up its display. The left side two segments on the units digit won't light up. So a digit 8, without the two vertical bars on the left, comes out as a letter E reversed left to right. Any digit that uses the two left segments (traditionally labelled segments E and F when talking about 7-segment displays) comes out wrong. Every thing else works fine. I can't tell if this is your problem.
This is almost surely a bad contact at the interface between the LCD display panel and the PC board: Typically there is a "squishy" conductive strip that connects them, and I expect grease has gotten in there. If so careful disassembly and cleaning with a mild solvent should fix it. Since we can live with it, and it usually fixes itself in a few weeks, I have not got around to taking it apart.

Quit working


SE probably means a sensor error.

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.

Otherwise, it may have a problem with the control panelm such as moisture or contamination or a bad connection.

Let us know if the hard reset doen't fix it, and please write back with more details if you need further help.
