Description
The Emerson Climate-White Rodgers 790-956A1 Flame Sensor is a combustion safety component used in a gas heating system. Designed to detect the presence of a burner flame, it generates a small electrical signal that is interpreted by the furnace control board to confirm successful ignition and maintain gas valve operation in HVAC systems. It is commonly installed in residential and light commercial furnaces where flame verification is required for safe startup and continuous heating performance. Within the burner assembly, the flame sensor operates as a monitoring part that supports ignition confirmation, combustion safety control, and coordinated furnace system operation.
