What Does Code 6 Flashes Mean?

Code 6 (6 Flashes) on the Amana AMSS920803BN indicates that the rollout limit circuit is open or the integrated control module fuse has blown. Flame rollout is a dangerous condition where flames escape from the burner compartment into the surrounding area of the furnace, which can cause fire or carbon monoxide exposure.

Flame rollout typically occurs when the exhaust flue or air inlet pipe is blocked, preventing combustion gases from being properly vented. The flames have nowhere to go but backward out of the burner opening. Misaligned burners, a failed induced draft blower, or a cracked heat exchanger can also cause this condition. The rollout limit switch is a safety device positioned near the burner opening that trips when it detects excessive heat outside the normal combustion area.

The 6-flash code can also appear if the control board fuse has blown, which may happen due to a short circuit in the 24-volt control wiring or safety circuits. Regardless of the specific cause, this code requires immediate professional attention. Do not attempt to reset the rollout switch or replace the fuse yourself, as the underlying cause must be identified and corrected first.
