Trane Furnace error code = 2 flashes, what does system lockout mean?
Asked Apr 16, 2009, 10:14 PM
I have a Trane forced air furnace which recently has had periods when it blows unheated air. When I looked at the furnace during these periods it shows 2 flashes, which according to the instruction manual is an error code which means: System lockout, retries or recycles exceeded.
I don't understand what this means and what is wrong with the furnace. Why does it blow warm air sometimes and unheated air at other times?
Thanks for your help.
