Armstrong Furnace R44992-001 Flame Sensor & Ignitor

The Armstrong Furnace R44992-001 Flame Sensor Ignitor is an essential part of an HVAC system and is designed for the ignition cycle, it checks for the presence of a flame, the ability of the gas valve to remain open to allow the burn only when the flame has been sensed. This sensor works by ionizing the air surrounding the flame and producing a minimal electric current to the control board. The benefits include reduction of gas leakage or explosion, efficient combustion hence energy conservation, and increased durability of the system.
