    The start pad will occasionally not work on a samsung microwave no matter
    how hard you press it, then a day or 2 later it works ok. All other pads
    work. Is there any way to repair this?

    Thanks

    There is most likely a cold solder connection, or a component that is
    mechanically intermittent, or a broken trace in the pad assembly, or at one
    of its connectors. If the pad is sitting on another board beneath it, then
    the problem may also be on that other board. The way that these are built
    you may have to replace the complete pad assembly, or an associated board
    assembly.

    Had a similar issue on my boat microwave. The ribbon connector from the touch
    pad to main PCB was the culprit. Unplugged it, cleaned it with aolcohol, been
    working for 5 years.
