Hi
I have a Carver fanmaster 4000 in my van and has been working fine up until these past few weeks if I leave it on electric 2kw/1kw with the fan its fine until the elements are hot and the fan is controlled, but then all of a sudden after a while the fan speed goes crazy and I can't control it other than turning it off or selecting gas or just the fan mode,
the heater itself is very hot the fan just speeds away regardless of the slider setting and if I move from 2kw to 1kw when this happens the fan gets faster.
Any ideas what this could be? I can select cold fan on the slider and move the speed fine so I don't think its the slider pcb?
Thanks
