I have a vacation home with a direct vent forced air heating system.
The furnace has gone off a number of times, and the heating contractor has told me that
1)I have to read the code (blinking lights that tell him what the problem is)
but that 2)He is pretty sure it is the wind causing a pressure switch to shut the unit off which he says is a problem in direct vent type systems.
I will get the code, but is what he says accurate? I was thinking i would put a little snow fence around the vent to prevent the wind from getting in to the system. It starts right back up with a power reset.
