I ordered pressure switch and cleaned pressure switch line and after 2 days later I noticed same problem again. Then I found water in the pressure switch line again. Checked in the morning found water again. Induced fan is hot and there should not be any mositure in it. Tube is connected top part of the induced fan and pressure switch has only one line comming from the induced fan. 11 years old furnace with electronic filter system and humidifier. I would like to know what happened on my furnace and how to fix?
