Description
The Trane SEN2145 1.5″ DS Flame Sensor (also available from multiple HVAC parts suppliers) is a genuine flame detection sensor designed for use in gas furnaces and heating systems. It’s engineered to reliably sense the presence of a flame during the burner ignition cycle and send that information back to the furnace control board. This essential feedback helps ensure safe combustion by preventing fuel from being delivered when a flame isn’t present.
Key Features
