    It is a combination of blown air and DHW heating, and have been made for a lot longer than that.
    It is well worth getting touch with Truma near Derby. They are better and cheaper than most dealers

    You have checked that there is a gas supply at the Truma, have you?
    Also what is the precise voltage of the 12v supply at the Truma? If the voltage is a bit low (corroded fuse holder, for example) the red light will come on.

    I had the similar thing happen a few years ago. It turned out a spider had crawled into the vent & blocked the gas jet in the burner.

    I sent the heater back to Trauma (intentional miss-spelling) after demolishing half the van to get the bloody thing out. They fitted a new burner & returned heater & old burner complete with spider, Cost me 75 quid plus postage.

    I now make sure the vent cover is in place when the heater is not in use.

    Thanks for all the replies.
    There is 12.7 volts at the boiler and I have checked all the fuses on the circuit board.

    There's also a fuse on the PCB, which might be worth checking.

    First thing to do is check the 12v supply entering the boiler with a multi meter.
    This will roll out any supply problems.
    If you get a 13-14v reading then this means that the supply is not the issue and the problem lies within the boiler.
    Next there will most certainly be a 12v 1.6a quick blow glass fuse within the boiler for further protection.
    You should be able to find it with not to much bother, check it for continuity.
    Also check that the fuses are held firmly within their holders, I have seen holders that widen with age and don’t connect properly with the fuse.

    If you don’t get a reading then you have a supply issue, ( your boiler is ok) which could be due to one of three
    Blown fuse, loose fuse connection, or damaged cabling.

    Go to the control panel and work your way towards the boiler checking for voltage at each stage.
    Also do a continuity on your multi meter to check for low insulation on your cabling.

    If you don’t have a multi meter I suggest you either get one, or borrow one from a friend.

    The fact that the boiler is not switching would suggest either a blown fuse, or a damaged relay.
    These are not specific boiler parts and will be available online.

    Hope you get it sorted.

    Just read this.

    This then is looking like either a faulty thermostat, or relay.
    Or you could have a faulty pcb.

    If your pcb is not surface mounted design and the older type with soldered connections then this would be more likely. But if you have an smd board itís unlikely to the board.

    As I said previously check that all the fuses are firmly affixed to their holders, and donít just do a visual, check their continuity. I have seen fuses that look ok only to find they are blown.
