You will find possibly the Magnatron has over heated and the sensor on top has activated. This can be possibly because the air intake to the magnatron is blocked or restricted. Clean vent and make sure it is not blocked off when oven is back in place. Need at least 120 mm air gap for good operation.

    When power went off and then came back on, screen on micro wave continually shows demo and I cannot set time

    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 and try again.

    If it still won't work, then you may have a bad membrane keypad / DP circuit.

    When pushed, the 30 sec button says 3 minutes. none of the display buttons work.

    Have you inadvertently programmed your microwave for "autostart"?
    Your model microwave has the ability to be programmed to go on at any given time of the day/night, even when you're not home so that you can have a defrosted and cooked meal waiting for you when you get in.
    I know that if you hit the 30 sec button or the minute button when your micro is programmed to autostart it will tell you the time that it's programmed to autostart or the amount of time that's left for it continue cooking.

    Have you tried unplugging it for a few minutes?
    This should clear it's memory and then all you'll have to do is set the time on the regular clock if you want.

    Here's where you can download and read your owners manual for further instructions on how to use the autostart feature and everything else:

    Sparks and strange noise when microwave is turned on even when empty inside. i have a ge jvm1850smss over the oven microwave.

    YOU SHOULD NOT RUN MICRO WITHOUT ANY THING IN IT / THIS WILL OVER LOAD THE MAG TUBE . AND SOME TIMES FRY IT .. The sparking and arcing is probably a bad wave guide . this is sometimes caused by food splater / it gets in the cracks and corners and then cooks till it truns to carbon which conduts the micro's and thus arching .. clean it good and touch up any burns in the metal and repl wave guide cover. mm hope this will help .. mm

    Microwave will count down the time but will not heat up

    Only one thing heats in micro wave. If every thing works but heat, sounds like you have a bad mag tube. (Magnitron)

    Micro wave does not work EM-Z2100GS

    First you check the fuse at the out put of highvoltage of the transformer. If the fuse is ok, replace the magnetron.

    Kenmore Microwave Problem

    "d" may mean demo mode.

    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.

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