Ive has an issue where the truma blown air heating cuts out giving a flash code that translates to either the fan , temperature sensor or the PCB being faulty and causing the heater to shut down due to over heating. The van is brand new and its one this only happens when the heating is running full whack on blown air.
If the blown air tubes are restricted it can cause this type of fault, but they are all clear.
Ive had a truma trained technician take a quick look and he told me he had never seen insulation fitted to the hot air pipes where they leave the boiler and suggested that its possible that too much heat is being kept inside the boiler due to this insulation. The boiler is fitted under the half dinette seat so doesn't have a massive area to dissipate heat.
Ive removed the insulation from the tubes for the area inside the seat and have tested the boiler around 4 times today and the fault hasn't shown. I'm going to run it again tomorrow to be sure that its definitely cured.
Does anyone else here have a truma 4E Boiler, and are your blown air pipes insulated where they leave the truma?
