Wayne cartmell Posted August 11, 2019 My trumatic heater works fine apart from the fan. Is it on its own fuse @ the fuse board. The index suggests its not, was working then nothing wayne Quote Share this post Link to post Share on other sites
Jaydug Posted August 11, 2019 The fan unit works off 12volts taken from the caravan battery although a few caravans appear to be fitted with a mains transformer. If it's not working it may be a fuse. On the other hand there's a pcb fitted close to the fan which may have a fault. Finally the switch on the top of the fire cover may be faulty. The wiring which connects the selector switch to the pcb has a push-on connector at both ends. It might just be that one of the connectors has become partially dislodged.
