Hi 

i have a problem with the ducted heating fan switch in my caravan

it is a Truma S3002 heater, the fan runs very slow when in the electric mode but blows very fast in gas, i have tried a new switch but it was the same, the only way i can get the fan to blow full speed in electric mode is to push down on the seector part
of the switch, (this was the same with both switches)

has anyone noticed this problem before? and if so is there a soluion?

many thanks

Al
