Pressure Switch Question
I have been having issues with my pressure switch opening up when the furnace is running. I suspect it is either windy conditions causing a back draft or ice in the intake. We have been having extremely cold weather with wind.
My pressure switch has 2 hoses, one goes to the inducer motor and the other goes to the fire box next to the intake pipe. What is the purpose of the second hose?
If I disconnect the hose going to the firebox could this help if it is the wind causing a backdraft?

The quick answer is no...... you can't run the furnace without both lines connected.
A make and model of your furnace would be needed for an accurate answer.
You'll find the model number on a tag on the side of the furnace near the burner area.
