First, be sure the child lock is off. It may have an "L" or the word "LOCKED" showing in the display.

You can unlock it by pressing and holding the CLEAR pad for 5 seconds or so. Your model may use a different key, maybe the "0" (zero) key.

If that doesn't fix it, since it's still under warranty you should grab your sales receipt and your owner's manual and call vendor's(make of your oven) customer service to find the nearest authorized servicer.

There may be some foreign substance on the circuit board or inside the layers of the keypad. Most commonly this is due to spray cleaner being sprayed directly onto the keypad.

Cleaner should be always sprayed on a soft cloth first, then use the cloth to wipe the keypad clean.

Always use alcohol-based cleaner on microwaves, never ammonia-based cleaner, which can crack and/or warp the plastic.

If this is what has happened, it would not be covered under warranty, and it may or may not be repairable.

A handy person can remove the control panel frame and see if there's any liquid inside on or behind the panel.

If so, it is possible to dry it out with an air compressor or heat.


Otherwise please contact any nearest repairman.

The top quick access buttons stopped working 2 days ago. The bottom buttons still work but, we can't punch in a custom time. The only thing that will work is the 1 for 1 minute 2 for 2 minute...etc.


One of two things is happening, either you have broken connections in the membrane switches of the keypad and should replace the keypad(which is most likely) or your main control board has failed in a way that it can no longer read signals sent by the keypad.

My LG Microwave is not working. The STOP/CLEAR button does not work

Lights come on, but can not program unit, Touchpad dead If you have a stuck key or non-responsive key, most of the time you will have to replace the keypad for this microwave oven repair. If your keypad is connected to your control board by a flat ribbon wire, try disconnecting it and clean the silver contacts with an ordinary pencil eraser. After cleaning, plug it back in and try it. If it doesn't fix it, replace the keypad unit. Some units actually have keypad tests to confirm your diagnosis of a bad key.
If your keypad and control is the same unit, replace that unit. Another note, unlike stove/oven keypads and controls, most microwaves do not have error codes or tests to distinguish whether it is truely the keypad or control. Most of the time, it is the keypad that needs replacing, but a small percentage of the time it can be the control. Check the tech sheet if they can point you to the right part.

Normally, it suggests the keypad is faulty. The fact that you have part function indicates the board is functioning. Replace keypad.

The Keypad stopped working


I suspect you atually have a bad keypad, but apparently GE decided to send you some free gifts? Wow. Sell them on eBay if they're not needed. *grin*

Replacing the keypad is usually a pretty easy job for a DIYer.

In many cases, it may be caused by steam or grease, but it may also just be a failure over time. I always recommend that you use the vent fan whenever you're cooking on the stove top. That helps keep steam, grease and heat away from the microwave controls.

We have *critical* safety, disassembly, and troubleshooting info at our site. You'll find a link to our site in 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 very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting. You can use it for testing your keypad.

If you need further assistance, please feel free to contact me directly through the links at our site: http://tinyurl.com/yzjozk

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

The Keypad is a Circuit.Each of the Function Buttons is a switch. The same "Touch" Techinology as is used of your TV Remote Control Pad or your Telephone. It would appear that your Keypad Circuit is Open, not allowing touch commands to reach the Control Board.The Keypad will have to be replaced. Best done by a Professional. I have seen "Rare" cases of a defective Door Switch causing such symptoms.
