I expect you will find the door interlock switches caused the main fuse to blow.
Check and replace the faulty switches.

Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Microwave clock and panel was lit in am wasn't used but in evening when went to use it isn't lit and won't work at all

Hello Anonymous

At the risk of starting with the very basics, when you say that the clock and panel aren't lit and wont' work at all, the first place to look is the wall power. You may be missing power from the wall because:
  1. The microwave isn't plugged in. Someone may have yanked a plug to plug in a mixer, phone charger, thanksgiving animated ornament, or what have you. Trace the cord back and make sure it's plugged in.
  2. Make sure the outlet has power. Take some plug-in-able item and plug to the outlet and see if it can turn on. If not:
  1. A number of kitchen outlets may have GFI switches, especially if they are anywhere near sinks. The GFI may have been tripped. There should be a reset switch in the middle of the plug. See if it's tripped, and reset if necessary.
  2. The breaker may have been tripped. Most kitchen circuits are wired to 20Amp breakers. If this is elsewhere in the house, like in an entertainment room or such, it is likely a 15 Amp outlet. Microwaves can draw a fair amount of power. Someone using another kitchen appliance, hair dryer, or what have you, on the same circuit, may have tripped the breaker. Newer code may specify an AFI or GFI breaker for kitchen outlets. In that case, a fault with something else on the circuit may have tripped the breaker. If that is the case, and it trips again, talk to an electrician. You don't want a fault like that undiagnosed.

    3) You may also want to try plugging the microwave into another outlet, even if the normal outlet seems OK

    If there's wall power and a good plug-in, then you work back to the microwave itself. A number will have fuses. Also, there may be interlocks that kick in if, for instance, the carousel rotation is impeded - that can mean something on the carousel is hitting a wall, which can risk tipping something over and spilling, or risk mucking up the reduction gears for the carousel axle if it keeps pushing.

    At that point, looking for specifics on your microwave model will be needed. You may also try the Microsoft Support approach - i.e unplug it for 5 minutes, then plug it back in and see if it works.

    Hoping this helps, Good Luck!

Micrwave not working

see this causes and fix it. God bless you
If the microwave will not work at all, make sure power is on at the outlet and test the electrical cord. Test the fuse and replace it if it is faulty. Also check the door to make sure it closes properly. Test and, if needed, replace the fan.
If the oven doesn't cook or cooks only intermittently but the display is on, check the door interlock switch, the thermal cutout and the fan, replacing parts that don't pass the test.

    The fuse keep burned every day I do replace the fuse, what is the wrong with my Kenmore micrwave 565.61589011 model. Thank you

    Chances are that you have a common connection with another plug. Microwave, Fridge etc.. Even if it's not the same plug it's still "In line" meaning that both outlets are on the same breaker. A: Find another outlet to plug your Microwave into or B: Put a surge protector in between the Microwave and the outlet.
