Description
The York S1-025-32661-002 is a genuine OEM replacement flame sensor engineered for York furnaces and heating systems. Designed to deliver precise and reliable flame detection, this sensor plays a critical role in your system’s safety sequence — confirming that a flame is present after ignition and signaling the control board to keep the gas valve open. If the sensor fails to detect a flame, the system safely shuts down, preventing unburned gas from accumulating.
Installing an authentic York OEM flame sensor ensures proper fit, function, and longevity — eliminating the guesswork and potential compatibility issues associated with aftermarket alternatives. Whether you’re performing routine preventive maintenance or responding to a nuisance lockout condition, the S1-025-32661-002 is the correct factory-specified replacement to restore your system to peak performance.

Why Replace Your Flame Sensor?
Over time, flame sensors accumulate oxidation and carbon buildup on the sensing rod, which insulates the rod and reduces its ability to detect the microamp signal produced by a burner flame. A degraded sensor can cause the furnace to light briefly and then shut off, leading to repeated ignition attempts and lockout codes. Replacing the sensor with a genuine York OEM part restores proper microamp readings and dependable system operation.
