The Trane SEN00388 radiant sensor detects burner flame and radiant heat to confirm proper ignition, telling the control board it's safe to keep the gas valve open. A dirty or failed sensor causes the furnace to ignite and then shut down within seconds, tripping repeated lockouts and leaving you with no heat. This OEM sensor restores reliable flame detection on compatible Trane furnaces.
