    Ah, that makes more sense.

    My first suggestion would be to look at the connections to that control to make sure that none of them have failed.

    Is it one of these?

    Would this be useful?

    The plastic cover on many hybrid circuits can be removed by prying on its edges where it's glued to the base/heatsink. Be careful not to slip tools inside though..
