    Hey everyone.
    Seeing as winter is approaching...may as well finally ask.

    So my thermoking apu has been acting funky since last winter.
    I just did maintenance on her including new hoses, belts, fluids, glow plug, etc.

    SO! The main problem I'm having is the bunk heater, she runs for 30 mins hot and then shuts off for the rest of the night with the apu still running...
    Any ideas?

    What's the thermostat set at? I've seen mine do something like you're talking about if I set the temp too high to begin with; say its 40 and you set 80, goes to beat hell and that's all she wrote. Could be overheating, and that's probably a slow switch to reset, for safety no doubt.

    Have you changed the fuel filter?

    Just checking.

    I'm thinking it's a temp sensor, however I don't have the tools to fix that ATM. And on top of that I can't find the darned thing!
