Williams P271100 Flame Sensor providing a robust path forThe 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
