Description
The Bard HVAC 8554-019BX is an OEM replacement flame sensor designed for use in compatible Bard heating and HVAC systems. Featuring a .114″ sensing rod, this component provides accurate and dependable flame detection to confirm proper burner ignition and maintain safe system operation.
How It Works
Flame sensors operate on the principle of flame rectification. When a burner is lit, the sensing rod is exposed to the flame and passes a small electrical current through it. The control board monitors this signal to verify that combustion is occurring. If the flame sensor fails to detect a flame — or detects a weak signal due to a dirty or degraded rod — the control board will shut down the gas valve as a safety measure, preventing unburned gas from accumulating.
