SEN01114 Flame Sensor Replacement is a precision-engineered component designed for Trane and American Standard furnaces. This stainless steel flame sensor rod serves as a direct replacement for multiple OEM part numbers including SEN337, SEN0337, SEN441, SEN00491, SEN1114, SEN0441, SEN491, PSE-T19, and B340888-2.

Constructed from corrosion-resistant stainless steel, the sensor rod ensures long-term durability and stable performance in harsh furnace environments. The metal structure resists oxidation and heat damage, allowing consistent flame detection over extended usage cycles. This replacement part matches original specifications, making installation straightforward for technicians and DIY users alike. The sensor operates by detecting the presence of a flame through electrical conductivity, sending a signal to the furnace control board to maintain gas flow. Reliable flame sensing is critical for safe and efficient furnace operation, preventing gas leaks or ignition failures. The stainless steel construction provides excellent thermal conductivity and mechanical strength, ensuring the rod withstands repeated heating and cooling cycles without deformation. This component is suitable for residential and light commercial heating systems that require periodic sensor replacement as part of routine maintenance. Compatibility extends across a wide range of Trane and American Standard furnace models, reducing the need for multiple inventory parts. The precision-formed rod tip ensures proper alignment within the burner assembly, supporting consistent flame reading. Manufactured with attention to dimensional accuracy, this sensor minimizes variance from OEM parts, promoting seamless fit and function. The affordable price point makes it a practical choice for homeowners and service professionals seeking cost-effective maintenance solutions without compromising on quality. This flame sensor is packaged in protective materials to prevent damage during shipping. The stainless steel surface is clean and free from burrs, ensuring safe handling. While the sensor can be installed by individuals with basic electrical knowledge, consulting the furnace manual or a professional is recommended. Regular replacement of flame sensors as part of seasonal maintenance helps sustain heating efficiency and reduce the risk of system lockouts. The combination of durable materials and budget-friendly pricing makes this component a sensible option for furnace upkeep.
