    Hi
    We have a hymer with a Truma C3402 water and air heater. Recently the heater started to go to lock out. After a bit of checking and contacting Truma the problem was narrowed down to the gas valve coil on the air heating side. When the unit was turned on for hot water only it works but on water/air it lock out. Trying to find the coils on their own is proving to be a test! But I can now see that it is possible to buy a wiring harness. Does anyone know if the harness includes the coils, overheat seniors, etc. this might explain why I can't see the coils on their own.

    Regards JA
