I do seem to collect all the problems ! Number one son has just joined us with a motorhome after selling his caravan It is a nice unit dating from 1996 on a Sprinter chassis ( cannot remember the body makers ) Sorted out most of the little niggles but there is a biggy. It is fitted with a Carver fanmaster hot air system .. the one with the all singing all dancing controller that switches from 12 to gas to mains.. The motor its self was siezed solid ( sorted that out easy enough ) but the controller board looks like it has been on fire ! Anyone got any idea where a new unit can be bought from ?
