My furnace will not ignite after power returning after being off for 10 days due to freak october storm. The error on the trane furnace is 3 blinks indicating a fault with:
DRAFT PRESSURE ERROR
a.) Venting problem
b.) Pressure swutch problem
C.) Inducer problem
Any help appreciated
This is a gas fired, direct vent 2 stage condensing furnace with variable speed inducer
The wind might have actually blown so hard that it messed up the drafting for the furnace temporarily, and it locked out. Turn the power off to the furnace for a minute, and turn it back on. This resets the board. Perhaps it will start then.
