Hi
I have the truma dual fuel blown air heater in my 2006 sprite major 6, just 
recently the heater stays on ,on low power it seems, even when the selector 
dial/thermostat is in the off position, also it might be  my imagination but 
the blownair system doesn't seem to be as warm as it used to be( not that it 
was that warm anyway), we bought the van new, and it had its first service 
end of last year and no problems were highlighted then, I wondered if anyone 
has had a similar problem.
thanks
Richard
