description

The Trane / American Standard SEN00073 is a genuine OEM flame sensor designed for compatible Trane and American Standard gas furnaces. Identified by the manufacturer as SENSOR; FLAME, this component is used to detect the presence of a burner flame during furnace operation.

The SEN00073 Flame Sensor is an important component of the furnace ignition safety system. Once the burners ignite, the flame sensor provides a flame-proving signal to the furnace control board, allowing the system to confirm that combustion has been established.

A dirty, damaged, or malfunctioning flame sensor may cause the furnace burners to ignite briefly and then shut off, resulting in interrupted heating cycles or furnace ignition lockouts.

Designed as an OEM replacement component, the Trane SEN00073 helps restore proper flame detection when installed in approved furnace applications.

HVAC Depot Pro Tip

A malfunctioning flame sensor is one possible cause of a furnace that lights normally but shuts off after a few seconds.

Before replacing the Trane SEN00073, inspect the existing flame sensor for contamination, damage, or corrosion. Also check the sensor wiring, burner grounding, and furnace control board.

Common symptoms associated with flame-sensing problems:

  • Furnace burners ignite but shut off shortly afterward
  • Repeated ignition attempts
  • Furnace enters ignition lockout
  • Intermittent heating operation
  • Flame-sensing diagnostic fault codes

HVAC Depot Pro Tip: A dirty flame sensor can sometimes be cleaned using the furnace manufacturer's approved maintenance procedure. If the sensor is damaged or fails to provide a proper flame-proving signal, replacement may be necessary.

Important: Flame sensors are safety-related components. Never bypass a flame sensor or operate the furnace with a defeated safety circuit.

Disconnect electrical power and follow manufacturer service procedures before installation.

Equipment / Model Compatibility

The Trane / American Standard SEN00073 is intended for select gas furnaces requiring this specific OEM flame sensor.

Exact compatible furnace model numbers have not been independently verified.

Before ordering, confirm:

  • Complete furnace model number
  • Furnace serial number
  • Original flame sensor part number
  • Sensor mounting configuration
  • Electrical connector and sensor geometry

Compatibility Notice: SEN00073 is not a universal flame sensor. Confirm manufacturer-approved fitment before purchasing.
