    Trying to do popcorn in a microwave popcorn bowl it cuts power after 5 minutes and then power comes back after 5 or so minutes. Try to finish the bowl of popcorn and it cuts out after 2 or 3 minutes. Seems to be over heating but only with popcorn like this.

In most cases, this is a problem with the inverter or a bad magnetron.

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

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

I cannot get the GE microwave clock to set! Help?


To set the clock on most GE microwaves:
1 With the microwave door closed, press CLOCK.
2 Touch number pads that reflect the time of day (1:45 would be 1, 4, 5).
3 On some newer models, indicate AM or PM for morning or evening.
4 Press CLOCK or START to lock in the time.
If you prefer not to display the time:
Disconnect the power for 30 seconds. After restoring power, do not set the clock. If your model has an ON/OFF clock display, you can choose not to have the time displayed. To choose this option, press the 0 pad for about three seconds. To Turn the display back on, press the 0 again.

I have a Panasonic microwave convection that runs for 2 or 3 seconds, then cuts off. It doesn't matter what setting or length of time you program into it, it will run a couple of seconds and shut down. Is...


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 and 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.

That 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.

Operation manual is lost, how do I set the clock?


The manual for the Magic Chef MCD1311ST Microwave can be downloaded in pdf format from the following site (follow the link then click the "Manuals" tab):
http://www.mcappliance.com/mwodetailpage.aspx?ModelName=MCD1311ST

If you don't have time to download, here's what the instructions state:

SETTING THE CLOCK
When the oven is first plugged in, the display will flash ":0" and a tone will sound. If the AC power ever goes off, the display shows ":0" when the power comes back on.

1. Touch CLOCK pad.
This is a 12 hour clock system.

2. Touch CLOCK pad once more.
This is a 24hour clock system.
NOTE: This oven has multiple clock system. If you want 12 hour clock system, omit this step.

3. Enter the correct time of day by touching the numbers in sequence.

4. Touch CLOCK pad.
The display stops blinking, and the colon start blinking. If you selected 12 hour clock system, this digital clock allows you to set from 1:00 to 12:59. If you selected 24 hour clock system, this digital clock allows you to set from 0:00 to 23:59.

5. Touch STOP/CLEAR pad.

NOTE: If you attempt to enter an incorrect time, the time will not be set and a error signal tone will sound. Touch the CLOCK pad and re-enter the time.

Can't set the clock on a 1987 Quasar Superwave convection Microwave MQ8777BW


I had a similar problem--no manual--but found this way to set the clock:
1) Be sure colon is flashing (unplug and replug)
2) Press the 10 HOUR/MIN, 1 MIN, 10 SEC/MIN, and 1 SEC/MIN buttons until the correct time displays.
3) Press the CLOCK button.
Hope this helps.

Microwave will turn off a few seconds after start.-


It seems there is something wrong either with the builtin controls or the buttons. It needs to be examine by a professional.
