looks like our touchpad for our W256B double oven when out, whit the touchpad plugged in it beeps like crazy and display is constantly changing. I've put an ohm meter across ribbon cable and don't see any continuity on any of the buttons. How do I test this touchpad. I'd buy a new one if anyone still had them but looks like they quit making them in 2009. Thanks

Thanks for the reply, mine has 12 pads. So essentially I should be able to put ohm meter across 10 and 3 and press upper bake and should show continuity correct?

yeah I've put ohm meter across one pad then pushed button and then touched to each other pad and didn't get anything. I don't think my touchpad is out completely cause some buttons work I just think one is stuck because it is always trying to set timer.

... you'd then have to "put ohm meter across the" second pad then push button and then touch all remaining pads, etc, etc, etc

yeah I tried that and didn't get a reading from any of the buttons which seemed odd because some of them still work. I tried 200ohm and higher with no luck. No biggie, thanks for the help
