Your touch panel is likely experiencing a failure. You may need to replace the control panel but there is a trick you can try first. Cut the power to the appliance. Use a hair dryer to heat the panel up until very warm while "massaging" the buttons. Often times, this will restore operation. Be sure to get the panel very warm but not hot enough to damage the plastic. If this does not work, the panel will need to be replaced. Let me know what happens and I can get you the correct part information.
I tried the hairdryer idea but it didn't help. Anything else we can try? What is the part number if I need to replace the panel?
I'm not sure it is the touch panel. I took the panel off and looked at the circuit board. It is pretty dirty; there had been a bug problem before. I used some alcohol and cleaned the board a little bit. I reconnected power and now several of the lights are on but they are actually bright now instead of very dim. I am intending to clean the board completely and then attempt to put it in diagnostic mode as suggested in the beginning, but I need to disconnect the board from the touch panel. It has a 15 pin ribbon cable but I can't seem to figure out how to disconnect it. Could you help?
I understand I still may need to replace a part if cleaning up the circuit board doesn't fix it, but how will we know if it is the touch panel or the circuit board itself?
I actually did just get it disconnected. I am cleaning it now. Any ideas how we would tell if it is the circuit board or the touch panel?
No luck. As I mentioned before, when I cleaned the board just a little bit before, more of the lights were on brighter. Now that I have finished cleaning it and cleaning the connectors, it is back to only having the "Washing" and "Pots and Pans" lights on very dimly (how it was originally).
Okay, I'm ordering the part and will have it by 10/3 to see if it solves the problem.
Thanks for your help
I installed the new touch pad and it is working again! Thanks for your help.
