I am having a few issues with My gas furnace. Luxaire PBLU-LD10N060A
The pressure switch that is monitoring the burner box seems to be taking on water.
I pull the tube from the burner box side and the induction fan side. I blow air into the burner box side and water comes out of the induction fan side.
The water impedes the operation of the pressure switch and it does not fully actuate the relay.
What could cause the pressure switch to be taking on water?

A gas furnace produces significant amounts of water vapor. This water vapor is condensing in the inducer blower pressure tube. I would see if the tube can be tilted to drain back into the combustion chamber. There should be a draining mechanism and the drain tube may be clogged.
