OEM Carrier Flame Sensor Assembly LH33WZ005 for Model PY1PPA048080AFBA

This OEM Carrier flame sensor assembly (part number LH33WZ005) is the factory-authorized replacement for the Carrier PY1PPA048080AFBA packaged heat pump unit. The flame sensor — also called a flame rod — monitors the burner for a live flame signal and reports it back to the integrated furnace control board. When the sensor rod becomes coated with oxidation or carbon buildup, its microamp signal weakens below the control board's threshold, causing the system to shut down on safety lockout — typically 5 to 8 seconds after ignition. Replacing a failed flame sensor is one of the fastest, most cost-effective furnace repairs available.

• OEM vs Generic: This genuine Carrier OEM sensor is manufactured to exact factory tolerances for microamp output and rod geometry. Generic sensors may use inferior alloys that degrade faster under high heat cycling, leading to repeat failures.
• Install difficulty: 2/5 — Shut off gas and power before starting. Tools needed: 1/4" or 5/16" hex driver, needle-nose pliers, and a multimeter (to verify microamp draw post-install). Photograph existing wire routing before disconnecting. Most technicians complete this swap in under 15 minutes.
