How to Fix / Troubleshooting
Safety First: Turn off power and gas immediately. A rollout condition is a serious safety issue. Do not repeatedly reset and operate the heater until the cause is corrected.
- Inspect rollout switch: Locate the rollout switch near the burner area. If it has a manual reset button, press it once after the unit has cooled. If it trips again, stop and investigate further.
- Check for soot and blockage: Look for black soot around the burners or flue outlet, indicating poor combustion or blockage. Do not operate the heater if soot is present.
- Examine burner area: Ensure no debris, spider webs, or rust flakes are blocking burner ports.
- Professional service: Flame rollout often indicates serious combustion or venting problems. Contact a qualified technician to clean the heat exchanger, verify combustion, and replace any damaged rollout switches.
