Description
The Lochinvar & A.O. Smith 100208462 is a genuine OEM replacement flame rod designed to deliver accurate and dependable flame sensing in compatible Lochinvar and A.O. Smith heating equipment. Flame rods are a critical safety component in gas-fired boilers and water heaters — they verify the presence of a burner flame and send a signal to the burner control system, preventing unburned gas from accumulating in the combustion chamber.
Why Flame Rods Matter
A properly functioning flame rod is essential to safe burner operation. When the rod detects a flame, it completes a small rectified current circuit that confirms ignition to the control board. A worn, cracked, or contaminated flame rod can cause nuisance lockouts, failed ignition sequences, or — more critically — unsafe operating conditions. Replacing a faulty flame rod with a genuine OEM part restores reliable flame detection and keeps your system running safely.
