Gusty Winds Effect Pressure Switches?
Posted: Thu Feb 14, 2008 6:08 pm
Coleman Mdl# DGAA056BDTA... I have a zone heating system using two of these furnaces. When the winds are gusting 30 + MPH, the furnaces error out with 3 flashes (Combustion Air Switch Failed to Close). The Booster Assy is running on both units. I have checked the lines and orifices to make sure they are clear. When the wind dies down, they seem to cycle normally, but once in a while I will continue to get the same failure (Combustion Air Switch Failed to Close).
Is this a common problem with these furnaces/pressure switches? I had one of the pressure switches replaced last year (P/N 024-27666-000), but both furnaces are acting up.
One last question.... do these pressure switches seem to be a high failure item ????
