York furnace flash error code 6 times (blowing cold air)
Asked Dec 10, 2008, 08:52 AM
I have a York (forced air) gas furnace that's 9 years old. Every winter it seems like I have to replace the pressure switch ( round switch with 2 connections & air hose). I hear the blower come on, burners ignite and then within a few seconds they go off with the red light flashing 6 times. Blower continues to blow cold air and stops. Checked the air hose & it's connection hole for blockage and they are clear.
I have repalced the pressure switch last year because of the same problem, it seems like it works for a year and then it goes bad. I appreciate any suggestions,troubleshooting tips or advise.
Thank you very much in advance!
