Question

I have a Truma s3002 heater in my motorhome. The heat output stays on full power now. Turning the control back to 1 makes no difference. What part needs replacing?

Answer

The gas supply to the burner is controlled by the gas valve, our ref 128056. The symptoms indicate a fault with this valve.
