The York S1-025-53193-000 is an OEM replacement flame sensor featuring a 90-degree bend configuration, engineered specifically for compatible York heating systems. Flame sensors play a critical role in furnace safety and operation — they detect the presence of a burner flame and signal the control board to keep the gas valve open. Without a properly functioning flame sensor, the furnace will shut down on lockout, preventing unsafe gas accumulation.
