    i have a 1990 Hymer 644. The green light on the boiler system turns on and after 10 seconds the red light comes on. If anyone has any suggestions they would be much appreciated.. Also need to source where the appliance cut off valve is? Thanks

    Not enough or no gas getting through.
    Vent cover still on.
    Gas exhaust fan not working.
    Thermocouple failed.

    Probably the PCB gone US.....it happened to my 12volt and gas Truma boiler, but as I wanted one that operated on the mains as well as 12 volt I replaced the whole boiler with a new one.The PCB from Truma is pricey but there are ones on EBay available, and as they just plug in are reasonably easy to replace. The only wiring to change over is the 12 volt feed....ie the brown and blue wires, the controller wire is only plugged into the PCB.
    ps, I'm presuming you boiler is a Truma?..

    We need more information about the "boiler" system before we can give any meaningful advice. Which boiler is it (make and model No please).
