Condenser dryer main board power fault

[Tha fios agaibh]

Sorry, I meant to say "Yes, that's what I was referring to". (the program dial)

I don't know how the controls tie in. Discrete inputs, or UART com connection that feed back to processor?
If one doesn't toggle high/low properly, it may lock you out.
Similar to how a keyboard won't work if a key is stuck and you try and press another.

Just a thought.

Ok, thanks.

Perhaps I should look into how to interface with the uC via KN9 just to see if I am at least able to handshake with it.
