If no one can tell you for certain then this info might help. I can't remember the colours positions but if the red/green and the brown/green leads are thick leads and the black is a thin lead, then the black goes on the N and the other leads go on L and C if the door locks then thick leads are correct positions if door does not lock change thick leads around. In the above instance you cannot harm the switch, if wrong you will just put 2 neutrals on the switch heater. tip... take a photo before removing wires on future repairs :-) Cheers
