If the control panel lights up intermittently, then you either have a loose connection somewhere near the panel, or a failing component on the circuit board itself.

My microwave recently stop working then I unplug it then start working then after few days I need to keep unplug it works but not working at all when I on it the display shows see the manual


Could be the outlet that it is plugged in,turn the circuit breaker off,wait a few minutes,then try again ,or it is pulling to much power from the outlet,something else might be pulling from it,maybe try plugging it in somewhere else.

The control panel of microwave dead. No lights on the panel. There is power to the outlet


If it worked after unplugging and reinserting, it is possible that there is a wiring problem with the plug and wiggling the wires "re-made" a connection. Try plugging in to another outlet to eliminate a dodgy outlet problem.

I have a GE Spacemaker microvave oven that was working perfectly for the past 4 years. When installed, we were told that the outlet did not work, so to get the microwave working, the cord was pulled out...


Perhaps the microwave's main supply fuse has blown.Open the cover & check it in the power supply section.Be careful & discharge the big capacitor first as there is very very high voltage present inside even after switching off.

I have a Frigidaire FMV156DBA built-in over-the-counter microwave that started behaving erratically tonight. The light started blinking on and off, accompanied by a repeated beeping. I unplugged the unit...


Yes have it serviced. Sounds like there is a loose/corroded connection inside and loose connections can cause fires. The intermittent/ramdom operation is indicative of this.

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.

Emerson Microwave


Did you unplug it for several minutes and them plug it back in?

If that dosn't resolve your problem, it sounds to me like the microprocessor controller board has failed and will need to be replaced.

Please let me know if I can be of further assistance to you.

Good luck!

Microwave has no power


Is the outlet ok? Can you plug somethng else into the outlet to see if the fuse or breaker controlling the outlet is ok? If there is power at the outlet, unplug the unit and remove the outside cover.
Look for a blown fuse on the motherboard. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged. Was this a power outage or surge? Was anything else in your home affected?

Panasonic microwave s254bf stopped working


A microwave can be dead for many reasons.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the thermostat to

open. When it cools, it closes the circuit and allows power through again.

If it's random, it may be a bad connection, usually on the control board or fuse holder.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If the fuse is good, it may be an open thermostat or thermal cutout on or near the magnetron or on top of the cavity / body of the oven.
