the circuit board
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 7 months ago

This has a board for blower and then also a separate ignition module...which did you replace?

Customer reply replied 7 months ago
we replace the main board . . . we gave you the board number
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 7 months ago

I wanted to verify because that is simply the blower board and has nothing to do with ignition.

That is why I ask twice if the damper door for the burner is rotating open..the board you replaced does not come into play until after ignition
