How to Fix / Troubleshooting
Safety: Turn off gas and power before working near burners.
Steps:
- Locate the flame sensor electrode near the gas burner.
- Clean the sensor rod gently with fine steel wool or a Scotch-Brite pad to remove oxidation.
- Ensure the burner and mounting brackets provide a solid ground connection; clean any rust or grease.
- Inspect the flame sensor wire for cracks or burns and ensure it is firmly connected to the ignition module.
Corrective actions:
- Replace the flame sensor / igniter assembly if the ceramic is cracked or the rod is heavily pitted.
- If proper flame sensing still fails, the ignition module may be defective and should be replaced.
