Amana AMSS960803BN Error Code 6 Flashes: Rollout Limit Circuit Open / Control Board Fuse Blown
What Does Code 6 Flashes Mean?
Six flashes on the Amana AMSS960803BN Integrated Control Module mean the rollout limit circuit is open. Flame rollout is when burner flames extend out of the burner compartment instead of drawing cleanly into the heat exchanger, and the rollout limit — a switch mounted near the burner opening — trips when it senses that abnormal heat. The board shuts off the burners and keeps the circulator blower running to move heat away.
On this furnace the most common trigger is a blocked flue or combustion-air inlet pipe: when exhaust cannot leave, combustion gases and flame push back out of the burners. Misaligned burners, a failed induced draft blower, or loose wiring can also open the rollout circuit, and in some cases the rollout limit itself has failed.
This code sits in the same limit-safety family as the four-flash code, but it is far more serious. Four flashes (Primary or Auxiliary Limit Circuit Open) is an over-temperature trip usually caused by restricted airflow across the heat exchanger, while six flashes means flame is actually escaping the burner box — a direct fire and carbon monoxide risk. A rollout condition should never be reset without finding and correcting the cause, so Amana treats this as professional service requiring inspection before the furnace runs again.
What You'll Notice
- The furnace stops heating and the diagnostic LED flashes six times, pauses, and repeats
- The circulator blower keeps running with the burners off
- You may notice soot, scorching, or heat discoloration around the burner compartment
- There may be a hot or burnt smell near the furnace
Common Causes
| Cause | Likelihood | DIY? |
|---|---|---|
| Flame rollout from blocked flue or air inlet pipe | Most common | ✗ Call a pro → |
| Faulty rollout limit switch | Uncommon | ✗ Call a pro → |
How This Is Diagnosed
Because rollout means flame left the burner box, a technician treats the whole combustion and venting path as suspect before the furnace is trusted again. They inspect the flue and air-inlet piping for blockage, proper length, and correct termination, check burner alignment and the heat exchanger for cracks or blockage, and verify the induced draft blower is moving combustion air correctly. Only after those are confirmed is the rollout limit itself tested and, if faulty, replaced. This is safety-critical work and must not be reduced to a homeowner 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:
- The rollout limit has tripped and the furnace shows six flashes
- You see soot, scorch marks, or discoloration around the burners
- There is a burnt smell or any sign of flames outside the burner box
- The code returns after any attempt to restart the furnace
Frequently Asked Questions
Can I just reset a 6-flash rollout code on my Amana?
No. Flame rollout is a fire and carbon monoxide hazard, and the rollout limit must not be reset until a technician finds and fixes the cause. Resetting without a repair can put the burner flames right back where they should not be.
What usually causes flame rollout on this furnace?
The most common cause is a blocked flue or combustion-air intake that stops exhaust from leaving, forcing flames back out of the burner box. Misaligned burners or a failed inducer motor can also trigger it.
Is it safe to keep using the furnace until the technician arrives?
No. Leave the furnace off until it has been inspected. A working carbon monoxide detector is important, and if an alarm sounds or you feel ill, leave the home and call for help.
