Trane Furnace Blinking Red Light Codes | Furnace Reviews (http://www.furnacereviews.net/trane-furnace-blinking-red-light.html)

Below is the identification list for a Trane furnace's blinking red light:
Flashing Slow — Normal – No call for heat
Flashing Fast — Normal – Call for heat
Continuous ON — Replace IFC
Continuous OFF — Check power
2 Flashes — System lockout (retries or recycles exceeded)
3 Flashes — Draft pressure error – possible problems: a) venting problem, b) pressure switch problem, c) inducer problem
4 Flashes — Open temperature limit circuit
5 Flashes — Flame sensed when no flame should be present
6 Flashes — 115 volt AC power reversed, poor grounding or system voltage too low
7 Flashes — Gas valve circuit error
8 Flashes — Low flame sense signal
9 Flashes — Check ignitor circuit and line “N” to 24VAC “common” voltage (<= 2 volts) [possible grounding problem].
