How to Fix / Troubleshooting
Safety: Do not repeatedly reset a furnace that fails to ignite; unresolved ignition issues can be hazardous.
Steps to check:
- Power reset: Turn off power to the furnace for 30 seconds, then restore. Observe the next ignition sequence carefully through the sight glass.
- Watch the sequence: Confirm inducer starts, pressure switch closes, ignitor glows, gas valve clicks, and burners light. Note at which step the sequence fails.
- Address root cause: Clean the flame sensor, inspect the hot surface ignitor, and verify gas supply as described in other entries. Correct any obvious issues before attempting another reset.
When to call a technician: If the furnace repeatedly enters lockout after resets, a professional should perform a full combustion and safety check.
