Hi im having problems with my truma 3002 fan operation.
the van is not working correctly ,
ive replaced the the unit on the front of the fan that controls manually and automatic (with the dial speed 1 - 5)
having replaced this the fan still only works at one intermitant speed ,on turning the dial the spped does not alter and on switching to auto the speed is still the same
im stuck could it be the pcb unit on back of fan ???
Still is this speed fast ,ie flat out? would you say or a slow speed?
point being if the pcb on the back of the fire has failed with fan still able to run, then in my experience it fails with fan running flat out.
Have you then carefully checked the wiring loom for chaffed and damaged wiring?
As I said, have your checked the wiring loom? I can't obviously be sure but to me the new switch is not connected correctly to the pcb in the fan housing so unable to instruct it
