    Air dryer goes off every 10 seconds. Can the problem be in the compressor governor or the dryer itself Cummins 350 HP

    Air leak in the line to the governor that it monitors the pressure in the system. As soon as it leaks down and starts charging the system it shuts off and the dryer unloads. Chek the line from governer to the air tank

    Do a search as I thought someone else posted something like this a few days ago. It was something about the drier freezing and he fixed it with air line anti freeze.
    I also could be wrong about it being the same issue too.
    Good luck

    change the governor and service the drier. it has a desiccant cartridge that needs to be replaced every 1 to 2 years
