I think that I need either a membrane switch or logic board. Does anyone have any troubleshooting instructions? There was a similiar post but the link to the instructions is no longer active. The have intermittent problems with 1) the dryness setting cycling continuously through 'damp dry' to 'very dry'. 2) the upper cabinet turning on by itself or when the lower cabinet 'start' button is pressed. 3) the 'time dry' and other buttons do not respond. 4) the unit will turn itself off during a cycle and cannot be turned back on 5) and now the entire unit powers off when I push the 'Start/Pause' button. That makes the unit unusable.

Should I just go ahead and buy both parts and return the unused item? Any reason to suspect a different part?

Thank you in advance
