KB3300 Stainless Steel - Display not working

Hi -

The display doesn' t light up at all - the surface top works but the oven/microwave doors are locked. I tried unlocking but nothing happens when the display is touched - no lights either. could it be the electronic panel or is there maybe a fuse that needs replacing?

Thanks!

    i stated with the same problem.

    I replaced a thermal protection fuse and the microwave, oven light and control panel apparently work.

    However, the oven will not bake or broil.

    The control board lights up and allows me to set the temperature, but no heat at all.

The control unit (circuit board) uses a relay and motor to lock the door, and the board may be damaged or scrambled

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.

If that doesn't fix it, it may need to have the control unit repaired. We do that for folks nationwide for only $39.95 in most cases.

We have the service manual for this model, and I've uploaded it to our site for your convenience:

    What if you can't move the oven by yourself and there's no obvious way to unplug it? Get a large man to visit? My Amana has weathered many a power outage with no problems, but the last one, which lasted less than a minute, seems to have overwhelmed it, and none of the digital stuff works. The range top is fine, but baking? Uh-uh. I don't want to be sticking my head in the oven to try to determine if it's heating up, or how hot it is! Lori in North Dakota

My GE stainless steel 1100 watt microwave starts beeping out of the blue and the display panel shuts off and when I open the door it resets itself and then starts to beep when I close the door again.


Try removing the power cord for about a minute, push all the touch pad 'buttons' and then plug it back in. If this doesn't work it sounds like you may have a bad door interlock switch or a bad PCM .. Good luck !

Have a 12 year old kitchenaid Superba stainless steel built in microwave. I suddenly stopped and "door' lights up on display. Door is shut hear clicking by left side may be a latch issue. How do you fix?


Hi - it is 12 yrs old so parts may not be available for it.

If its a door problem, then its really a door latch switch or switches that has failed. Time involved in removing case, then switches then checking them all then finding replacements at ?? cost is uneconomic.
Please consider getting a new machine - probably use less power, have more features and work a darn sight better than this old one.

My daughter did something to the door... when you close the door and set the time and start the display reads 'DOOR' as if it isn't closed and it won't start. Thanks for any assistance. Whirlpool...


i have seen this a few times. the m/w portion has seperate fuses and sometimes the cartridge fuse can be blown. it is located inside the top above oven. hard to get to without pulling the unit and getting the top off of unit.
others have had a failure in the microwave control board.

Know display anel getting EXTREMELY hot


Laura_kucari

I think you are feeling the heat coming from the oven vent. The fan still runs as it tries to cool down the temp in the compartment housing the electronics.
