OEM Carrier Flame Sensor LH680013 for Model PG9MAB048080ABSA Gas Furnace

This OEM straight flame sensor (part number LH680013) is the factory-specified replacement for the Carrier PG9MAB048080ABSA gas furnace. The flame sensor is a safety-critical component — a small metal rod that generates a microamp DC signal when it detects a live burner flame. When the rod becomes coated with oxidation or carbon buildup, the control board can no longer verify ignition and will shut off the gas valve within 5–8 seconds of startup, causing a no-heat lockout condition that repeats on every cycle.

• Part Number: LH680013 | Also replaces LH33WZ516, LH33WZ514 | Straight rod configuration | Factory OEM specification
• OEM vs Generic: The OEM sensor uses precision-grade stainless alloy that maintains stable microamp output across thousands of ignition cycles. Aftermarket sensors can produce erratic readings that trigger nuisance lockouts or, worse, fail to detect a dangerous flame-out condition.
• Install Difficulty: 1/5 — One of the easiest furnace repairs available. Tools needed: 1/4" hex driver or flat-head screwdriver. Turn off power and gas, remove the single mounting screw, unplug the wire harness, and swap in the new sensor. Total job time: under 10 minutes.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
