Product is GE Microwave (Spacesaver-type) JNM1731DM1BB. New surface light bulbs installed. Unable to turn them off or change from bright to dim


Bottom lights are controlled through relays on the main control board which is mounted on the back of the touch pads (control panel).You can check and see if wires are touching each other on the board but my guess is the board is defective and needs replaced.

Panosonic Microwave convection Model NN-8501V Touchpad appears dead


The unit has a fuse in the power board, but when the fuse is gone it does not even start up. If it starts it is not the fuse.

Look rather a problem with a faulty touchpad, or the magnetron that is not working and need to be changed.

Check also the door sensor.

Most of the time the panel buttons stop working because grease gets between the outer panel and the contacts underneath. Disassemble the door and if you need to carefully peel back the outer panel, use some paper towels to remove the heavy grease, then using a Q-tip and some rubbing alcohol clean the back of the panel and the surface contacts on the board, then re-assemble.

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.

It may be a glitch that can be corrected by a hard reset. Unplug it from the power line for a minute, plug it back in, set the clock, then try again.

It may have gotten moisture, contamination, or grease inside, which can happen if one cooks on the stove top without having the microwave's hood vent fan on.

It may simply need repair.

Microwave came on by itself


Yes this is usually caused by the touch assy, but $278 !!!!! Thats kinda steep considering the panel assy is only around 30-60 bucks!!! It will need the touch assy and even possibly the control board, because sometimes the logic IC gets fried and causes "ghost issues" as well.
