Switch is inside so remove sheet metal. switch is on right side front and usually mounted with screws. Some are soldered to a circuit board. Remove switch and replace. Might have to move mechanism out of the way to install sw. There are numbers on the switch so you can find a replacement.
good luck!!!

SOURCE: microwave will not turn on.

Bad switch alignment. Some models can have an adjustment. Look carefully at the latch for any sign of damage. There are three switdhes that must simultaneously be activated, or the oven won't work. If, during the operation of the oven, the door is opened and the switches DONT simultaneously trigger, the monitor switch will detect this condition and short the incoming power directly to ground, which will blow the internal fuse, and possibly also trip the circuit breaker.

Sorry to read about your problem, I hope this helps you out.

you will have to contact a service company, microwaves are complex. if you order a part and try to fix, their are no returns. plus lg parts take a long time to get, and then way the cost of repair.

Microwaves must be serviced by technicians due to the inherent dangers involved in repairing these appliances. Internal capacitors can retain a lethal electrical charge even though the unit is completely unplugged. A microwave radiation leakage test must be performed on the unit following any internal component repair.

You almost certainly have a bad membrane keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a
handy guide with pictures showing you what's typically involved.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

But please note that for some GE models, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame.
That is a simple do-it-yourself job.

Either way, we can let you know what your options and costs would be and send you other helpful info.

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.

Feel free to contact me
directly (and please remind me of your full model number from the tag on the unit) for more information & help.

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

Microwave will not run a cook cycle. Touchpad functions until door is opened or start button is pressed. When door is opened display goes dark. When door shuts display lights all characters and then says...


BEFORE DOING ANYTHING DISCONNECT OVEN FROM POWER. I do NOT recommend doing repair by yourself, if you NOT are really very familiar with electric repair, or have at least basic training in electric device repair and maintenance.
"When door is opened display goes dark. When door shuts display lights all characters and then says "touch clock"."
Obviously, by opening door, oven gets disconnected form power line.
This is mostly caused by loose connections on wiring socket, and can be anywhere inside. Check security micro switch on door latch. This switch normally disables only running the oven when door is open, for security reasons. In your case, it seems that opening door disconnects oven from input power. Sometimes the switch is loose, or wires are not firmly pushed in the socket. If the power line wiring is loose, and by opening door looses contact with socket, it can touch metal housing inside, cause short, electric shock, serious even mortal injury and fire. This is dangerous high voltage switch, and to access it one must open oven from the back and take off the cover. I do not recommend doing it by your self.
Rem: Replacement micro switch is couple dollars.

Microwave touch pad not working


test 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.

My microwave panel is not working.


Sometimes if the door switches are faulty then the touch panel may not respond. There are usually 3 switches, and I'd recommend if one if faulty replacing all of them as a set. Otherwise it may be a Control Panel fault.

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. Other times, it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

One test that sometimes helps is to gently lift up on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There may also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

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

The keypad is available separately (you have to peel off the old one and stick the new one on) for about $36 plus shiping. It is also available preassembled with a new control panel frame and display for about $78 plus shipping. They are available from Tritronics at http:www.wehaveparts.com BUT - I would first suspect and check for a failing door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a file called "safety.txt" which is of vital importance. You can find these files via a Google search. In some cases, the problem is a bad connection or a bad relay on the control board. That's something we see from time to time, and we repair those nationwide, but it's usually a door switch. If you still have a problem, please write back with more detail. Be safe!
