Amana AMSS920803BN Error Code 6 Flashes: Rollout Limit Circuit Open / Control Board Fuse Blown
What Does Code 6 Flashes Mean?
Six flashes on the Amana AMSS920803BN report that the rollout limit circuit is open or the Integrated Control Module's fuse has blown. Flame rollout means flames are escaping the front of the burner compartment instead of being drawn cleanly into the heat exchanger — a serious hazard that can damage the furnace and produce carbon monoxide. The rollout limit is a safety switch mounted near the burners that trips when it senses heat where there should be none.
Rollout on this furnace typically follows blocked venting: a plugged exhaust flue or intake pipe leaves combustion gases nowhere to go, so flames roll back out toward the burners. Misaligned burners or a failed induced-draft blower that cannot establish proper draft can cause the same thing. The identical six-flash code also appears if the board's 3-amp fuse has blown, usually from a short in the 24-volt control or safety circuits.
This code is more severe than four flashes (code-4), which is an overheat from restricted airflow with the burners simply shut off. A rollout means combustion itself has left the burner box, so the furnace must not be returned to service until the cause is found and corrected.
What You'll Notice
- The furnace is dead or will not start, and the single LED blinks six times
- You may notice soot, scorching, or a burnt smell near the burner area
- Signs of a blocked or damaged exhaust or intake pipe may be visible outside
- The furnace shut down abruptly and will not restart
- A carbon monoxide alarm may sound if venting is compromised
Common Causes
How This Is Diagnosed
A technician inspects for physical evidence of rollout such as scorching or soot at the burner front, checks burner alignment, and examines the flue and intake for blockage, improper length, or a covered termination. They verify inducer performance, test the rollout limit, and check the board fuse and the 24-volt circuit for a short. The furnace is not returned to service until the actual rollout cause is corrected, not merely reset.
When to Call a Professional
This code involves components that are not homeowner-serviceable, so have a licensed HVAC technician diagnose and repair it. Keep in mind:
- Six flashes appear at all — treat this as inspect-before-operating
- You see or smell soot, scorching, or burning near the furnace
- The exhaust or intake pipe looks blocked, disconnected, or damaged
- The code returns after any attempt to reset it
- A carbon monoxide alarm has activated
Frequently Asked Questions
Can I just reset the rollout switch and keep using the furnace?
No. A rollout means flames escaped the burner compartment, which can damage the furnace and create a fire and carbon-monoxide risk. It must be inspected and the cause corrected by a technician before the furnace runs again.
What causes flame rollout on this furnace?
Most often blocked venting, misaligned burners, or a failed inducer that prevents proper draft, which lets flames roll out toward the front instead of drawing into the heat exchanger.
Is six flashes a carbon monoxide risk?
Improper combustion and blocked venting can produce carbon monoxide, so treat six flashes seriously — keep the furnace off, make sure you have working CO alarms, and get it inspected promptly.
