OEM Carrier Flame Sensor w/ Wire LH680014 for Model PG8JAA042090AAJA

This is the OEM factory-specified flame sensor with wire harness for the Carrier PG8JAA042090AAJA gas furnace. The flame sensor is a critical safety component in your furnace's Hot Surface Ignition (HSI) system — it detects the presence of a burner flame and signals the control board to keep the gas valve open. When the sensor becomes coated with oxidation or fails entirely, the furnace will ignite briefly and then shut off within 5–8 seconds as the board reads no flame signal, triggering a safety lockout. Replacing the sensor with an OEM part ensures the correct rod geometry, wire lead length, and kanthal rod material rated to withstand temperatures up to 1,800°F.

• Specs: 45° rod angle | Kanthal flame rod | High-alumina ceramic insulator | Includes wire lead | Replaces LH33WZ515, LH33WZ511, LH680012, LH33WZ517, LH680534
• OEM vs Generic: OEM sensors meet exact factory tolerances for rod angle and wire gauge. Generic sensors may use inferior rod materials with lower temperature ratings, increasing risk of nuisance lockouts or premature failure.
• Install difficulty: 2/5 — Turn off gas and power before starting. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect wire lead, remove single mounting screw, insert new sensor, reconnect lead. Total time: 10–15 minutes.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
