Question

Hello Tom, I have a van with a Truma c6002eh heater, it has been playing up for a week or so before finally stopping altogether, can you tell me this, although the air circulation fan turns as soon as switched on, I have taken the combustion fan out to check that, despite a 12 volt supply reaching it, when the boiler is switched on it does not turn at all could this be the reason the boiler does not attempt to run, many thanks.

Answer

If the combustion fan is not operating then the boiler will register a fault immediately.
