T23A-1 is identical to T23A-1C

this kit transitions legacy pilot assemblies to a more reliable intermittent pilot ignition configuration

this sensor monitors the burner flame and transmits a microamp signal to the control board to verify ignition

Precise LP Regulation: Calibrated specifically for Liquid Propane at 10

the control must be mounted separately from the main electrical cabinet to prevent potential migration of ammonia into sensitive electrical components

Trane KIT15815 Furnace Control Freon T23A-1 is identical to T23A-1CThe Trane KIT15815 Furnace Control is a critical OEM ignition control module designed for high reliability performance in Trane and American Standard gas furnaces.
