How to Fix / Troubleshooting

Critical safety warning: Flame rollout and blocked heat exchangers can cause carbon monoxide exposure. Turn off gas and power immediately and do not operate the furnace.

  • Visual inspection: With power off, inspect around burners for signs of scorching, melted wiring, or tripped rollout switches.
  • Check venting: Ensure vent and intake are not blocked and are properly connected.

Diagnosis of heat exchanger integrity requires specialized tools and training. Contact a qualified Bryant technician to inspect and, if necessary, replace the heat exchanger or furnace.
