This model serves as the direct OEM replacement for P291-8053RS

providing a robust path for the high-voltage spark necessary for reliable burner sequencing and consistent flame proofing

Its dual-value output of 25 microfarads for the compressor and 4 microfarads for the fan motor delivers precise capacitance levels required to maintain peak operating efficiency and prevent motor overheating

preventing the costly heat exchanger damage associated with restricted airflow or over-firing

What causes a transformer to burn out

Williams P271100 Flame Sensor This model serves as theThe Williams P271100 Flame Sensor is a critical OEM safety component engineered for precise flame rectification in Williams Forsaire counterflow furnaces. This sensor acts as the primary safeguard for the ignition sequence, utilizing a heat resistant probe to detect the presence of a burner flame. By communicating a microamp signal back to the integrated furnace control, it ensures that the gas valve remains energized only when a steady flame is
