There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here (just enter your model number).

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

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

No power to microwave


Hello

Check the Power Cord

Verify that the power cord is properly connected the outlet; the plug might have been removed to make way for another appliance. Do not connect the microwave to an outlet via an extension cord or plug adapter; the oven must be directly connected to an outlet.
Switch the Outlet on

Turn the outlet on, if possible, using the switch on the wall behind the counter or on the plug itself. Some microwaves have a separate power switch that must be in the correct position before you can begin cooking.
Reset the Oven

Unplug the oven, wait a few seconds and reconnect the power. A power surge could have temporarily rendered the oven inoperable. The oven should start up as normal when you connect the plug to the outlet.
Check the Fuses and Breakers

See that the fuse or breaker protecting the oven's circuit is still active. Replace the fuse if it has blown, or reset the breaker to restore power to the oven. Stop using the microwave if it repeatedly blows fuses or trips breakers.

All of a sudden the microwave will not coming on at all no clock no nothing, it completely lost power. I've tried a different outlet and it has no power. Did it blow up?


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.

Machine will not turn on


from online Microwave Repair Manual: Totally dead oven (no lights, no clock, no display, no fan, no heat...)First, check power to the outlet using a lamp or radio you know works. The fuse or circuit breaker at your service panel may have blown/tripped due to an overload or fault in the microwave oven or some other appliance. You may just have too many appliances plugged into this circuit - microwave ovens are high current appliances and should be on a dedicated circuit if possible. If you attempt to run a heating appliance like a toaster or fryer at the same time, you *will* blow the fuse or trip the circuit breaker. A refrigerator should never be plugged into the same circuit for this reason as well - you really don't want it to be without power because of your popcorn!

If you find the fuse blown or circuit breaker tripped, unplug everything from the circuit to which the microwave is connected (keep in mind that other outlets may be fed from the same circuit). Replace the fuse or reset the circuit breaker. If the same thing happens again, you have a problem with the outlet or other wiring on the same branch circuit. If plugging in the microwave causes the fuse to blow or circuit breaker to trip immediately, there is a short circuit in the power cord or elsewhere.

The microwave oven may be powered from a GFCI outlet or downstream of one and the GFCI may have tripped. (Removing a broken oven lamp has been known to happen.) The GFCI outlet may not be in an obvious location but first check the countertop outlets. The tripped GFCI could be in the garage or almost anywhere else! Pushing the RESET button may be all that's needed.

Next, try to set the clock. With some ovens the screen will be totally blank following a power outage - there may be nothing wrong with it. Furthermore, some ovens will not allow you perform any cooking related actions until the clock is set to a valid time.

Assuming these are not your problems, a fuse has probably blown although a dead controller is a possibility.


While you can do some repairs on your microwave, what you don't know can kill you... even on an unplugged microwave, so make sure you understand the dangers and how to reduce them before you try anything inside a microwave. If you want to do more yourself, go to the link at the top of this post.
