    I previously posted about my bunk heater problem. But the video that was suggested, doesn’t address my problem. My heater works, to well, I start it and regardless of where I set the temperature, it just keeps getting hotter, till I have to shut it off. I need help with, is it the digi controller that is bad, or the ecm module, in the heater itself?

    So are you saying it keeps blowing full blast even after reaching set temperature.?
    Mine continues to blow but at a significantly reduced flow of air.
    Sometimes I just have to shut it off.
    Sometimes I crack both windows.

    No.
    And when you turn it off you need to let burn off before you start your truck.
    Takes 3 to 5 minutes , put your hand by the vent when it completely stops blowing you can start your truck.

    Sounds like you need to get it serviced.

    Your thermostat or sensor is in a position where it is too cold and gets no heat. Try moving it closer to where you usually are and see what happens.
