    The Sharp microwave is model number R-120D. It no longer goes on. I have cleaned the touch panel with water (like the manual states). Also changed the buttons on the outside doors. However, the ON button is the one that NO longer turns the microwave on. The entire touch panel works except for the on. Is their any hope this can be fixed. my wife loves the microwave.

Without your brand and model number, it's hard to give specific guidance, but when a microwave won't start, the first suspect is a bad door switch or door switch mount. See this file.

You mentioned that you clean the touch panel. I hope that a cleaning spray was not sprayed directly on the controls or on the oven. That's a big killer of controls.

My microwave LG MB-2341BR is not functioning as the touch panel not working. The start touch is not working. Do we get touch panel replacement now?


I being an experienced technician all I do is get micro buttons such as used in television set .I carefully apply minimal hot air from a hair dyer to the touch panel in a clean environment then strip the adhesive touch panel to check the wire ring that tress back to the pcb that is just beneath the touch panel. yo have to locate common and the wire responsible for touch, then drill a small hole where the micro button will sit solder to wires on the button then carefully solder them on the board.now make sure the button is on the same level with the surface before you return the adhesive touch panel make sure the button sits well then from beneath apply hot glue please don't use super glue if you don't understand I will send you pictures.

Touch pad doesn't work


Your touch pad is connected to your board with a ribbon wire, it has probably come loose. Unplug the unit and remove the face plate. Pull it back and you will see the wire, it looks like a ribbon, push it in tight, replace the face plate and it should work properly. I see this happen all the time.

Hello. I just received a new Glass Touch ASM (WB27T10875) for my GE stove. My previous one cracked and needed to be replaced. Problem: While installing/ connecting the ASM to the stove, once I connect the...


Funniest thing. I was having the very same problem on Monday. Every time I laid the glass touch panel down on the stove, it stopped working but worked when I held it up. After failing to install the panel so it would work for 30 minutes, I walked away from it and ate dinner. Coming back later, I decided my problem was the connections on the back side were coming into contact with the metal so I placed a tightening knob in the center of each of the outside holes making sure the underside of the knob went exactly into the middle of the hole. I then lowered the left side of the panel down to where the threads started and very carefully partially tightened the left knob so none of the panel back touched the stove. I then lowered the right side until the knob touched the knob and tightened that side finger tight. I keep testing the buttons to make sure they were still working. When the out side knobs were finger tight, I finger tightened the 2 inside knobs. Success. My oven is now working.

Likely when you cleaned it, grease mixed with the cleaner you used got between the button panel and the actual button switch behind the panel, making it stick on. Will need the model to determine how to remove the panel to clean underneath...OR, it may dry out and start working normally again.

Stuck Microwave door


The button assembly or the arm thats attached to the push button is broken. With the unit unplugged. Carfully take off the screws from the sides and around the back of the unit around the outside of the cover. Now once apart, DO NOT TOUCH any electrical parts. Look at the mechanism and see if you can see why the buttons not activating an arm to trigger the door latch. If you think you see why, Go to http://www.repairclinic.com and enter your model #.. Answer the questions and then a bunch of parts will come up. If they dont then get the tele # from there and call them. Depending on how old the oven is, you may want to consider a newer oven??. Good luck
