OEM Carrier Straight Flame Sensor LH680013 for Model PG9MAA060080ADKA

This is the factory OEM straight flame sensor for the Carrier PG9MAA060080ADKA gas furnace. The flame sensor — also called a flame rod — is a safety component that confirms active combustion to the integrated furnace control board. When the sensor detects a flame, it passes a small microamp current through the rod; if that signal falls too low or disappears due to a coated or failed sensor, the board shuts off the gas valve. The classic symptom is a furnace that ignites briefly, then shuts off after 5 to 8 seconds, repeating in a lock-out loop with no heat delivered.

• Specs: Straight-body flame rod | OEM part number LH680013 | Also replaces LH33WZ516 and LH33WZ514 | Factory-matched signal output for Carrier control boards
• OEM vs Generic: OEM sensors maintain precise rod geometry and insulator integrity for accurate microamp readings. Aftermarket sensors may produce marginal signals that cause nuisance shutdowns or false lock-outs, especially as they age.
• Install difficulty: 1/5 — One of the easiest furnace repairs. Turn off power and gas at the furnace. Tools needed: 1/4" hex-head driver or flat-blade screwdriver. Disconnect the single wire harness connector, remove the single mounting screw, swap the sensor, and reconnect. Always inspect the wire lead and connector for heat damage while the panel is open.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
