Description
Product Summary
The Supco FLS51M14 Flame Sensor 51M14 is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. SUPCO® flame sensors can replace many of the popular sensors in today's furnaces that use hot surface or direct spark ignition systems.
Hot surface igniters and flame sensors are the heart of modern gas furnace ignition. A cracked or weak igniter causes no-heat calls and lockouts, while a dirty or failing flame sensor causes the burners to shut down seconds after lighting. Match the igniter material (silicon carbide or silicon nitride), voltage, and mounting style to the original.
Key Features
- Alumina ceramic insulator
- For Hot Surface Ignition (HSI) systems
- Kanthal flame rod material can withstand 1800°F
- Mount on multiple burners, or adjacent to igniter
- See Downloads section for additional X-refs
- Use with spark ignition and flame sensing
- WARNING: Prop 65 info
