Amber flame LED RAPID BLINK

Unexpected flame

This code typically points to

Flame detected when not expected
Possible gas-valve leakage
False flame signal condition

Next checks to confirm

Verify whether flame is physically present when no call should exist
If no real flame is present, continue with flame-sense and gas-valve circuit checks in OEM troubleshooting

Escalation

Can participate in soft-lockout behavior when undesired flame is detected; accessible legacy snippet does not publish separate timing rule on this LED entry itself

Reset behavior

Clears when unexpected-flame condition is removed; if lockout has occurred, use published lockout reset procedure.

Safety Critical

Immediate concern
