hi welcome,

there is a way to record the fault code from your heater if its a combi type and i understand the control boards are replaceable :thumb:

Which fan do you mean, the distribution (recirculating) fan or the combustion air fan? Both are replaceable and more likely to be the faulty part than the PCB although that is a possibility too. Exactly what are the symptoms of your fault please?


P.s. C3402 i.e. a C series heater unit does not record/display faults like the later Combi does.

C3402 Fan

The Electronic Control box on the Truma C3402 has a fault, making the fan not work on the heating side, can it be repaired,

It is the fan that pushes hot air through the van, it is the Electronic Control, when I take the wire from the box the fan starts.

Can you be a little more specific, which wire and what control box? Do you mean the PCB which is attached to the heater unit itself or the control dial assembly?

Truma Trumatic

Hi Dave
The Truma book that came with the van is C3402/C6002
Written by another owner of the front of the book is C 603 - E - 15051280 if that means anything
In the installation book it is pictured N the box black on the side of the heater, I took off the cover at the top and took off one of the wires, and then the fan started to work.
The control board seems quite a lot of money, I did not look at it, and wondered if it can be repaired.

Not as far as I'm aware can it be repaired if its a PCB fault. Your best bet is to phone Truma tech support, they're very good at diagnosing faults but be prepared to do things as instructed by them.
