OMG NOT KITCHENAID!!!!! Problem is going to be with main control board. The Big Problems is 2 things actually 1 its Kitchenaid. It is going to be expensive to repair. and 2, trying to find a company that actually has the part. If you have the book that came with the unit, see if it has a phone number for warranty service for the unit. It may not be under warranty, but they will be the only ones who will have reasonable access to parts for it. I tell people NO when they call me and say they have a kitchenaid. Just too damn difficult to deal with. GOOD LUCK!!

First I would be sure the outlet is okay. You could try plugging a lamp into that outlet and wiggling the plug to be sure it's okay.

Otherwise, it may be a bad internal connection causing a power loss, or it has a problem with the keypad or control board.

I would suggest to check all the connections from the new installed parts and double check your switches.
Have you followed the user guide from page 35 to try to unlock that key?
If still does not work, there may be two possibilties that the new keypad(timer set-start button) may not work or the magnetron is defective.
Check this link as well for some additional info.

If you don't have the owner's manual you can download it here:

Some units will not allow time programming if the door is open - or if the microwave thinks it is due to a bad door switch or door switch mount, etc.

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

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.

If you or a friend 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: http://tinyurl.com/yzjozk

The issue is probably your exhaust fan on your microwave comes on automatically when it detects a certain temperature. Mine does this as well but will turn off automatically after temperature goes down.

"F2" means you have a shorting membrane keypad. The "Pan Heat" key is shorting.

On these 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.

You can find helpful exploded view diagrams and order parts by entering your full model number* from the tag on the oven here.

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.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame.

GE Advantium 120 gives message keypad shorted. None of the buttons are working. How can I order a new keypad?

please follow this steps before to order any keypads. God bless you
However if after you did this steps go to http://www.appliancepartspros.com

  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.

You probably have a shorted membrane keypad.

The problem can be intermittent, going away and coming back, but sooner or later it will be permanent.

On this model, 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. attached

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

It is part number WB56X10824 and you can order it from the Pros here for $135.33 (subject to change).

You can find helpful exploded view diagrams and other order parts by entering your full model number (JVM1540DN1WW) at that link, too.
You can find a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) and move your circuit board into the new frame. Be careful - the display is made of glass.

The problem is in the keypad control board, eventually it will need to be replaced, also there may be a intermittent short in the keypad membrane this is where a professional will be needed to make that determination.

I have samsung microwave model number ME 1240SC. my front panel touch screen is not working properly, when i press the keys it is not working. so i think i need to replace the touch screen. so please...

That model does not user a touch screen, it actually uses a standard membrane keypad.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes. Then try it again.

If it's still not responding, I would suspect your membrane keypad has failed.

Is it possible that some spray cleaner accidentally got into the controls?

Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

And I always recommend that you use the vent fan whenever you're cooking on the stove top to keep heat, steam, and grease out of the controls and door panels.

If it does not dry out over time, it may need to be manually dried or blown out.

The keypad may be damaged or worn out, or control unit may be damaged.

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.

If you wanted to order a new membrane switch / keypad, the part number is DE34-00145F and you can order it from the Pros here. They're our favorite supplier.

Otherwise, this is a pretty standard 1200W microwave, and you may find it better to simply replace it instead of repairing it.

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

Then please let us know if the hard reset does not fix it.

(It may need work on the controller or keypad)

F3 Error on Display

F3 on a GE / Hotpoint microwave means you have a shorted keypad.

Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

Always spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

If it will not successfully dry out, it will need to be repaired.

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

There should 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 would like to have us do this for you, we do that for $39.95 plus part costs.

Please feel free to contact me directly if you need more help.

Panasonic Panel Problems

Based on my 25+ years of experience, I would say the "8" key on the keypad is shorting, requiring a new membrane keypad.

Is it possible that some spray cleaner got into the controls?

I always recommend that users spray the cleaner on a soft cloth (not on the keypad itself) then wipe the control panel off.

Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.

Otherwise, the spray can get into the controls and lock it up or make it act odd.

If it does not dry out over time, it may need to be manually dried or blown out.

But of course, the keypad may be damaged or worn out, or control unit may be damaged.
