You have a failed membrane keypad.

Replacement keypads are no longer available for any Sharp R-9H-series microwave ovens.

The oven will have to be replaced.

Power Surge - GE Microwave


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.

Touchpad not working


please see the next step. and fix it. God bless you
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.

Sharp Carousel Microwave - R1481 keypad doesn't work


No! I'am afraid not, the problem is in the keypad control board, the whole assembly must be replaced, the part alone will cost around $100.00 or more depending on make and model.

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.

Keypad on ge spacemaker microwave oven not working


Needs a new touch pad if it doesnt respond, you can check the connection between the touch pad and the pcb, but it sounds like there is an O/C on the pad.

Sharp Carousel Model R9H84B


I've attached the portion of the manual which shows how to lock & unlock this model.

If that doesn't work, unplug the oven for one minute, plug it back in aga9in, then try again.

If it still doesn;t work, then your keypad has failed, and they are no longer available for these model, so the oven would have to be retired.

Good luck.
