Customer: replied 2 years ago.
code
Expert:  BillyHvac replied 2 years ago.
You have 3 choices,,,
open limit (you replaced)
open roll out (you replaced at least1)
Bad circuit board
You can hunt for more....but that is the extent of that code...limit, roll out, circuit board
Customer: replied 2 years ago.
to clear the flsh code do you need to reset anything on the furnace is it a lock out
Expert:  BillyHvac replied 2 years ago.
no..the only way it clears is to close the circuit. It resets by itself when open is gone
Customer: replied 2 years ago.
ok thanks i will have to dig deeper into this and do a complete check of all safety devices
Expert:  BillyHvac replied 2 years ago.
you will see if you follow the wires it is a one loop safety circuit...power leaves board goes through circuit..and returns to board.
something in the circuit id open...OR....the board is bad.
If all set just rate service so I can move from active list.
