Any ideas? Thank you

Hi Gary,

Make sure the booster motor is running full speed, vent pipe is clear and undamaged and the small tubes that are connected to pressure switch are tight and unclogged.


If all that seems ok, then probably pitted/corroded contacts inside pressure switch that intermittantly make contact and hold in closed position.


Best remedy for that is to replace the pressure switch.
