I all,
I have a Truma Gas/Electric heater in the caravan which has always worked perfectly on both fuels. However, on a recent outing in the lovely hail, snow and gales it suddenly stopped working on the electric and, as it's not safe to use the gas whilst asleep it meant a few freezing cold nights.
On returning home I have tested both fuses and have drawn a complete blank. Any ideas as to the possible cause/cure before I have to pay for the experts to have a look?
Hi Dave, no there is no light on the control switch on 500, 1000, or 2000. Does that mean it could be the control switch thats faulty, or is there a fuse or something controlling that as well?
Hi Les, it sounds to me like there is no 12 volts supply from the mains transformer to work the control circuit, a fairly common failure. If you can locate the PCB at the fire end, have a look at the transformer on the board, is it swollen on the top? If so, the transformer has failed and there are uprated ones available fairly cheaply.

Thanks for that Dave, you're a star. I will get on to that today. It never occurred to me that there would be a 12 volt circuit seeing as it's a mains heater. Thanks again.

Hi again Dave,
I guess that I didn't drop lucky on this one. I managed to get to the back of my Truma and locate the circuit board and the little grey transformer felt quite solid...... but unfortunately it is securely soldered to the board with quite a lot of solder points. I think that I may have to replace the whole board and guess that that's not going to be a cheap exercise.
Many thanks anyway Dave for your help....at least it gave me hope lol.
Les.

Hi Les, The whole panel is quite an expensive item because as yet we ain't sure if that is actually faulty and/or the only problem. Have you a means of checking input & output voltage? If you feel confident trying, then I suggest a fairly cheap voltmeter from Maplin's, Screwfix or the like and check what is and what isn't there. Be careful...
The transformer supplies 12 volts to the high voltage control side, so the little green LED should light up if it's there, it may be that there is no mains supply to it, check that first. Good luck.
