York S1-025-32661-002 Flame Sensor

The York S1-025-32661-002 Flame Sensor is a critical component for maintaining reliable furnace ignition sequences in high-efficiency York, Coleman, and Luxaire gas furnaces. This OEM flame rod utilizes flame ionization technology to detect the presence of burner flame, preventing the gas valve from remaining open if ignition fails. Built with a durable stainless steel probe and high-grade ceramic insulation, it withstands the harsh thermal environment of the burner assembly. If you are diagnosing a furnace that cycles off shortly after ignition, checking for carbon buildup or oxidation on this York furnace part is standard procedure. This specific HVAC flame sensor replacement features an offset mounting bracket for precise positioning within the burner flame path. Proper installation ensures consistent microamp signals to the integrated furnace control board, reducing nuisance lockout codes and improving overall heating system maintenance efficiency for your commercial or residential clients.

Key Benefits

• OEM direct replacement ensures precise fit and electrical compatibility with existing York control modules.
• High-temperature ceramic insulator prevents voltage leakage and shorts to ground, maintaining signal integrity.
• Stainless steel sensing rod offers superior resistance to thermal stress and atmospheric corrosion.
• Standardized spade terminal connection allows for rapid lead wire attachment during field service.

Common Questions

How do I know if the York S1-025-32661-002 is failing? When a furnace lights but shuts down within seconds, it often indicates the control board is not receiving the proper microamp (µA) signal. Technicians should use a multimeter in series to verify it meets the minimum threshold, typically 0.5 µA or higher.

Can this flame sensor be cleaned or should it be replaced? While light oxidation can be removed with a non-conductive abrasive pad, deep pitting or a cracked ceramic insulator necessitates immediate replacement to prevent recurring system lockouts.

Is this part specific to York gas furnaces? This component is engineered for the York family of brands, including Luxaire and Coleman. Always cross-reference the mounting bracket offset and probe length to ensure proper alignment with the burner flame.
