Erratic touchpad test results for failing Kenmore Elite Dryer
Model Number: 11062052100 Brand:
More than 10 years
The touchpad on this dryer has at times not responded at all, or worked perfectly, worked after unplugging, worked after working the buttons, beeped erratically during drying, worked after heating the back/front of the touchpad and/or control panel with a heat gun, etc. It has not worked consistently for more than 2 weeks at a time (usually stops responding to touchpad keys completely), in a long time. I have done the various key matrix resistance checks on the individual buttons, and at times all but a few of the buttons are bad (and it is not always the same buttons that are bad). Then I have tested it other times, and all test out good and the touchpad works perfectly. I'm inclined to think the touchpad is bad and not the control board except for the occasional beeping during a dry cycle. The beeping is the same as if I were trying to push a button during drying. Recently I tried stopping it while it was beeping and it just restarted on its own. Then I shut the "End of Cycle Signal" to "Off" and the beeping ceased and it stopped restarting on its own. Is there a good chance I'm wrong and it is actually the control board?
