Power Surge - GE Microwave

We had a power outage probably preceded by a power surge. The keypad lights but won't respond to touch. Does anyone know if this is a keypad problem, or is it likely to need a new control board? The latter costs more than a new microwave. Thanks.

See this steps and fix it. God bless you

  1. Controller is confusedA power surge or random non-reproducible action of the universe may have resulted in the controller's program ending up in an infinite loop. Pull the plug for a minute or two to reset it.
  2. Defective Interlock switchesThis can result in the controller thinking the door is open and ignoring you.
  3. CleaningCleaning solutions (spray cleaner) may have gotten inside and shorted out the touchpad or controller. If this happens remove the touchpad, let it air dry for a few days, and then attach it back on the microwave.

SOURCE: Reset Microwave after a Power Outage

If its part of the house your renting, call the landlord as its most likly a control panel went bad, and in this unit, thats probably going to exceed the cost of the microwave oven. If its a rental oven, take it back.

SOURCE: Microwave dead after power surge.

A) The fuse you change was the one on top just behind the control board? correct? Not the one on the door hinge side of the microwave. (as is is the Thermal cutout ) Then most likely took out the control board... i would also check the Capacitor and recifier let me know it this helped?

SOURCE: My RV unit got a power surge and the microwave looks dead.

Yes they have fuses, I am positive it's your fuse, take all 5 screw's off and you'll see it at the back on the right hand side were the ac cord goes in.

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 magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

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

You should do a continuity test the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

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 it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

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.

If it has a hood thermostat, that should read open, as opposed to the others, which should read closed.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

We're happy to help and we appreciate your thoughtful rating of our answer.

I had the EXACT same symptoms with my Sylvania SR1109sb after a power surge.
After some digging around I thought what the heck let me try holding down the Reset button and do a power off/on cycle and what do you know it worked !!!
Just pressing the Reset did nothing until the cycle off and on.

Samsung Microwave Oven SMH7159 No Power


The power outage may have been accompanied with a power surge. That can happen with lightning strikes, or if a large inductor (electric motor or equivalent) happened to be on the same power line at the time of the outage. There's a good chance a surge took out the control panel.

No! there is no reset, the power surge has more than likely damaged the keypad controller, and on the back is a circuit board that has the microprocessor with additional components that controls the vital areas of the microwave oven. If that is gone, it is cheaper to replace than to repair.

Hello. My Panasonic NN-K153W microwave owen keypad does not responding, beside three keys- stop, clock and the one with symbol of microwave in the left upper corner. I can not setup the clock because no...


Other than a complete power off, I know of no reset switch on any microwave ovens. I own a panasonic myself.

I would leave it unplugged for a while, at least 15 minutes or so, and leave the door open, to turn on the inside light (which won't light if unplugged but) so it might discharge any capacitors holding residual power to the circuit.

If it wasn't power protected, it could have taken a hit.

If it is plugged into a surge protector, they wear out. You might be able to make a claim on it through the surge protector manufacturer, if it has a warranty, and you have receipt. Surge protectors do wear out, and most unless they're the cheapest, will have a warranty that covers equipment. The wear out because the varistor which provides the voltage clamping during a surge become conditioned. Initially they clamp around 150V to 180V, but as they age from repeated surges, their clamping voltage rises until it no longer protects the equipment. Often you can tell, if the surge protector LED is blinking or intermittent, the company will replace the surge device if you make a claim on the protector, if it fails while in use, they usually cover the equipment, unless the warranty has run out, but many give lifetime warranties.

The reason some keys may have been working is because after a small surge, the logic states can go indeterminate, which means some work, and some won't. If it's not damaged, a full power off for some time may restore it to initial conditions.

Hope this helps. They should build in surge protection, and I think mind does have some; but, if not, I hope it's in warranty for you.

How do I get it out of lock mode


If the model number you have listed is correct, you turn the Child Lock feature on/off by pressing and holding the "Clear/Off" button for three seconds. The instructions are on page 28 of the Owner/Operator Manual.

If your model number is different from the one you have this question posted under, please post back with your correct information so that I may be able to provide you with better assistance.

I hope this helps you.

All 88888's on display after power outage can't program anything,


I bet you did not have a surge suppressor on it. Just checking.
Your PC board is damaged.

Next time you need a surge suppression.

I have one for $39.00 for this unit.

Microwave-doesn't warm anything anymore


Hello rarms1965... chances are that your microwave was the recipeint of a power surge during the power outage you mentioned.. there is no way of knowing what component took the brunt of a surge and it could very well be your magnetron tube, filament transformer of any number of control logic components.. The problem is that anytime you open the case to check things.. unless you know what to look for or even more so.. what NOT to touch ( High Voltage Capacitor comes to mind) you don't know what you are up against. If it isn't a real expesive model ( you didn't provide a brand or model with your inquiry).. then the cost to diagnose & repair could very well exceed teh cost to replace.. Your call.. but whatever you do.. be sure you KNOW what you are doing..
Good Luck my friend..

Kenmore Microwave 63252


Microwaves use a special ceramic fuse that has probably been popped by the outage. You have to take the cover off and it looks just like the regular cylindrical glass fuse except this one is white instead of clear. I think radio shack has them. Hopefully the fuse stopped the power surge before it got the front panel controls.
