Possible Causes
How to Fix / Troubleshooting
Critical Safety Warning: Flame rollout is a serious hazard that can cause fire or carbon monoxide exposure. If you see signs of scorching around the burner compartment, do not attempt to operate the heater. Have a qualified technician inspect it.
- Visual inspection: With power and gas off, remove the front panel and inspect around the burners and rollout switches for soot, discoloration, or melted wiring.
- Check rollout switches: Locate the manual reset rollout switches near the burner area. If they have a reset button, press to reset once. If they immediately trip again, stop and call a professional.
- Inspect for blockages: Look for debris in the burner area, blocked flue passages, or heavy soot on the heat exchanger. Do not scrape aggressively; this requires professional cleaning.
- Do not bypass safety devices: Never jumper or bypass rollout switches. If a rollout switch is faulty, replace it with the correct Rheem rollout switch.
