This complete assembly is critical for identifying potential burner issues or soot buildup without compromising the sealed combustion environment

acting as a high-limit safety mechanism that interrupts the ignition circuit if excessive temperatures are detected near the pilot assembly

or freezing condensate if the furnace is located in an unconditioned space

which is required for systems utilizing HFC refrigerants like R-134a

Verified Compatibility: Direct replacement for several Rheem and Ruud furnace models
