  • High pressure switch sticking open.

    5 cycles after rearranging my coalescing filter, priority valve and high pressure cut off switch my switch started sticking open???
    It had always been oriented with the gas inlet at the bottom and the gas inlet is now at the top.
    Does anyone know if pressure switches proper operation depends on orientation?
    I suspect the sticking open after inverting mine is not coincidence.
    Thanks,
    Karl

    Is the pressure switch now in an area that is prone to moisture from the coalescing filter? If it is, that is a sure possibility for problems.

      Interesting thought on moisture.
      The coalescing filter traps more oil than water as my gas is apparently quite dry.
      It is more likely it is collecting oil.
      In any case I am concluding that a pressure switch should not be oriented in such a way that it can accumulate anything other than gas or air.
      My plan is to reconfigure it so it is above the gas line rather than below it.

      Thanks for the input,
      Karl
