Possible Causes

How to Fix / Troubleshooting

Safety first: Turn off gas and power before cleaning or adjusting components.

Clean flame sensor: Gently clean the electrode/flame sensor rod with fine emery cloth to remove oxidation.
Check ground: Ensure the burner assembly has a solid metal-to-metal connection to chassis ground; remove rust or grease at mounting points.
Observe flame: When relit, the flame should fully envelop the sensor rod. If not, adjust burner alignment.

If the flame still drops out, a technician should test the gas valve and control board.
