Sumsung MU3250W shut down

All of a sudden, wegn using the microwave, after 3 seconds it shuts down and the timer pad reads 8888. I then reset the clock and try again. If works for 3 seconds and shuts down. I turned off the power (at the breaker) for 10 minutes to try to reset the internal breaker. Still happens. Light and truntable work until it shuts down.

The problem is your magnetron tube is leaking RF. The mag tube comes on 2-3 seconds after you hit start, and the RF interfears with the board and shuts it down. Drop the front of the control panel down and watch, it wont happen.. Get a new mag tube put in and you'll be good to go.

It can be a door switch issue or a bad door switch mount.

It can also be due to damper .

Most likely the problem is a bad control board which probably has some traces micro cracked, but before you replace it I would recommend to check how good the range is grounded.

It is most likely a internal protection mechanism, if your wave is still covered by the warranty suggest you contact your dealer for repairs.

Sharp microwave 8888 is flashing and I cannot remove


see this steps and fix it. God bless you

Reset the clock. Press "Clock" and the correct time, using the number pads. Press "AM/PM" if applicable, and press "Start" or "Clock" to confirm.

  • 2 Press "Timer On/Off" to reset the timer if nothing on the touch pad will operate. Use the number pads to select a new timed amount, if desired, and press "Timer On/Off" to start. Press again to cancel.
  • 3 Press and hold "Clear/Off" for three seconds if the timer will not function or is blinking when you touch the pads. This will release the "Child Lock" feature. Make a new touch pad selection.
  • 4 Disconnect power to the microwave if following Steps 1 through 3 does not resolve the blinking timer. Wait a few minutes, and then restore power to reset the microwave.

  • However if the problem persist the display board
    main control board is faulty

    Panasonic Microwave suddenly won't cook.


    Your microwave is detecting an internal shot and shutting down, Most likely due to a faulty Magnetron which is not a part that is worth replacing due to the cost of the part and the decrease in cost of new microwaves.

    How do I unlock the key pad? The display shows locked and I don't know how it locked.


    Here you go.

    The Child Lock shuts down the control panel pads to prevent
    unintended use of the microwave oven.
    When the control is locked, only the Vent Fan and Light pads will
    function.
    To Lock/Unlock Control: The microwave oven and Timer must
    be off. Touch and hold START for 5 seconds until 2 tones sound
    and a lock icon appears on the display. Repeat to unlock and
    remove the lock icon from display.

    Samsung MU3250W Shut down


    It could have been steam or humidity.

    If this is an over the range model, be sure you always use the hood vent exhaust fan when you're cooking on the stove top.

    Whether it's a counter top or over the range top, always be aware that the cooling fan is running when it's cooking.

    When in doubt feel for air flow through the vents.

    Good luck.

    Timer Shuts off after 5 seconds


    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.

    Is it 5 seconds or 5 minutes? The difference coulsd be important, but either could indicate a bad magnetron.

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

    Please write back with more details if you need further help.
