    When it goes into this "beeping" mode, does the display show any codes or anything unusual?

I started having the same problem with my KBMC140HSSO. You cannot see the error codes without disassembling the control panel (the codes are on another display that covered by the front panel). After doing so I found the error code to be F2, E3 which is "Key held down too long, or key shorted". I am ordering a replacement keypad and will report back if this fixes the problem.

    Replacing the keypad did fix the problem.

    I am having this beeping problem as well with my KBMC140HSS0. Did you replace the switch membrane (part number 4453025) or the electical control circuit (part number 4452482). Also, how to I get the front off to access the control panel?

make this test and fix it. God bless you


  1. Inspect the power cordUnplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switchIf your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fusesTo determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motorLocate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

HELLO.

The steps to the solution are as follows.

Off the microwave oven and it.

Then plug the microwave oven and power on the microwave.

Allow the microwave oven to load itself.

Then reset the timing program.

Test the microwave for normal operation.

NOTE:if the problem persist,cleaning the microwave is the next solution.Below is the solution to cleaning the microwave oven.
  • Remove oven racks and soak them in soapy water.
  • Turn on your automatic oven cleaner; this usually entails locking the door and turning the function switch to "clean."
  • Let the oven do its work; it will heat for several hours, charring off baked-on foods.

Thanks.

I have Emerson Microwave #mw8999sv which has the Express Cook option- cooking 1 - 6 minutes. How do I cook for 1 minute 30 seconds, etc.? Thank you.


The owner's manual is here. On page 10 we find:

COOKING IN ONE STAGE
1. Press the POWER button; the Microwave and High
Cook indicators will light and “PL 10” will light in the
display.
2. Press the POWER button different times to set the
desired power; the display will show the percentage
you chose. If selecting power level 70%-10%, the
Low Cook indicator will light instead of the High
Cook indicator.
3. Press number keys to set the desired cooking time.
OPERATION(CONTINUED)
4. Press the START/+30SEC. button to start cooking;
the Microwave and one of the Cook indicators will
blink and the display will countdown the remaining
cooking time in minutes and seconds. It will beep
five times when cooking is completed.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

GE xl 1800 beep


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

Let us know if the hard reset doesn't fix it.

Magic chef over the oven microwave shuts off.


Is not normal for a microwave to shutdown after 4 minutes of operation.
From the info you are providing, It looks like the magnetron might be overheating causing the thermal fuse to shut it down until it cools down. There may also be a loose connection in one of the switches or a cold solder joint in the low voltage power supply.
I would suggest to check and make sure that the fans are functional, If always did; it could be that there isn't much air circulation where the appliance was installed.
