Pressure switch stuck open Luxaire furnace
Asked Nov 5, 2010, 03:01 PM
I have a luxaire high efficiency furnace made in 1994 that is getting the error code for the pressure switch being stuck open. I took the rubber hose off to make sure it didn't have any holes or was clogged and then used a paperclip to clean out the connection by the fan, but it is still flashing 3 after I reconnected the hose. Is there anything else that I can try to do to fix the situation on my own or is it something that I NEED to call a professional to come fix?
Previous things that were replaced this year were the ignitor and flame sensor (dont know if that has anything to do with it but thought I would mention it)
