CODE
FAILED IGNITION
11
DESCRIPTION:
This fault is displayed when a failed ignition has
occurred three times in a row. The Core Command will enter a
one-hour lockout following the third ignition attempt.
CAUSE:
1. Flame sense rod is unable to sense flame
2. Gas valve is turned OFF.
3. The ignitor is not working properly.
4. The Core Command is not working properly
5. Burner flame is not carrying over from first burner to the last.
SOLUTION:
the solution will depend on the cause.
1. Clean or replace flame sense rod. Confirm flame sense is
in burner flame. Check wire and all connections between
flame sense and Core Command. Make sure furnace is
properly grounded.
2. Turn gas valve ON.
3. Replace or reposition the ignitor. Refer to section G.1.4 for
proper ignitor location. Check wire and all connections
between ignitor and Core Command.
4. Replace furnace Core Command.
5. Check manifold pressure during ignition (see Measuring and
Adjusting Manifold Gas Pressures section). Watch the burner
during ignition if the first burner lights but the second, third
and so on do not light (incomplete carry-over), the burner
may need to be replaced.

LOW FLAME SENSE
DESCRIPTION:
Furnace operation will continue in low and high-
fire modes. This problem may be elevated to the level of fault
code “13” or “11” if flame cannot be sensed at all.
CAUSE:
1. Most common cause is that the flame sense rod may need
cleaning.
2. Flame sense rod may not be properly connected.
3. Wiring between the rod and furnace control may be shorted
or opened.
SOLUTION:
1. Clean or replace flame sense rod.
2. Check wire and all connections between the flame sense and
Core Command.
3. Make sure the furnace is properly grounded.
