Microwave cooked dinner and now does work

Maybe time for a new one. But just in case check the power outlet still has power and the circuit breaker is not tripped.

the panel display is fried. you'll need to remove and replace it...this the sort of thing you enjoy doing?

Possibly the fuse / breaker is tripped, usually all outlets in one room share same breaker. Check breakers (or fuses) or try outlet in differnt room. If the outlet has power, (plugin a lamp to check) and the microwave still does not work, take it back to store for replacement or refund.

Hello

Look to see if the microwave power cord is securely plugged into a live power outlet. The power cord cannot be loose for proper function. Move other appliances to a separate outlet if possible.

Replace or reset the circuit breaker or fuse if blown or tripped.

Unplug the microwave and wait several seconds before plugging it back in to reset.

Make sure there are no current functions in use. Press "Clear/Off" to cancel any other settings or programs already in progress.


Select a new cooking program and then select "Cook Time." Make a time selection and press the "Start/Pause" pad to begin cooking.

Check your other appliance. You may have tripped a break. If they are all functioning, and you have no dead outlets in your kitchen, then the unit will need to be serviced. Hope it's the breaker.
a 1200w microware will draw 10 amps all by itself. Your outlets are most likely on 15 amp breakers, so it wouldn't take much amp draw from another kitchen appliance to trip the breaker.

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.

try the fuse

• Make sure that the microwave is plugged into a grounded outlet. It must be a 3-prong outlet.
  
• Make sure the clock is set.
• Check to see if a programming sequence was entered. Sometimes improper programming or a program sequence such as delay start can cause the touch panel to be non-responsive. Unplug microwave or turn off house circuit breaker for 30 seconds. Plug back in, or reset circuit breaker, and try reprogramming unit.
  
• Check the house circuit breaker or fuse box. If the microwave is DEAD and there is no display and nothing works- the problem could be a blown fuse or tripped breaker.

This often is a stuck or faulty door switch and it has blown the interior microwave fuse.

Since power = voltage X current, 1.58kW / 120VAC = 13.166A

So this unit should be fine on a 15A breaker unless the breaker is bad, the wiring or a connection is loose somewhere between the breaker and the microwave, or the microwave's magnetron or high voltage transformer are failing and drawing extra current.

Microwaves should really be on the own separate breaker if at all possible. Plus, the more a breaker trips, the more work out it gets.

Have you measured the voltage at the outlet? If that's off, current and power will be affected. It should be about 110-125VAC.

A good power test for outlet and wiring integrity is a toaster, toaster oven, or hair dryer rated at about 1500 watts.

If it doesn't run and heat steadily, then there may be a problem with the house wiring or breaker.

If it passes this test, the problem is likely in the microwave.
