Question

My Truma S3002 blown air heating only works on gas setting can you advise what I can do. I am a gas safe engineer but don’t have any caravan heater knowledge.

Answer

If the 230 volt Ultraheat system is not working then identifying the fault is not straightforward. It could be a problem with the heating element itself, the printed circuit board, the fixed thermostat or over temperature sensors or the wiring loom. you will need to have it checked at an Approved Workshop.
