OEM Carrier Flame Sensor Assembly LH33WZ005 for Model PY1PPA060080ADBA

This is the genuine OEM factory-replacement flame sensor assembly for the Carrier PY1PPA060080ADBA packaged heat pump unit. The flame sensor (also called a flame rod) is a critical safety component that detects the presence of a burner flame through electrical rectification. When the control board energizes the gas valve and igniter, it simultaneously monitors the flame sensor for a small microamp signal — typically 1–5 µA — that confirms combustion is occurring. If that signal is absent or too weak, the board shuts the gas valve within 5–8 seconds to prevent unburned gas buildup, triggering a lockout sequence. A failed, cracked, or heavily oxidized flame sensor is one of the most common causes of a furnace or heat pump that lights briefly and then shuts off immediately.

• Part Number: LH33WZ005 | Factory Authorized Carrier OEM Replacement | Includes 64½" wire lead assembly for correct routing
• OEM vs Generic: OEM sensors use the exact alloy rod and factory-spec ceramic insulator, ensuring consistent microamp output within the board's acceptance window. Off-brand sensors can produce marginal or erratic readings, causing nuisance lockouts or, worse, false flame confirmation.
• Install Difficulty: 2/5 — Disconnect power and shut off gas before servicing. Tools needed: 1/4" hex driver, needle-nose pliers, multimeter with µA DC range (to verify post-install reading of 1–5 µA). Lightly sand the rod with fine steel wool if reusing; replace if cracked or heavily scaled.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.
