OEM Carrier Spark Electrode Igniter LH33WZ008 for Model PY1PNA024040ACBA

This is the genuine OEM Carrier spark electrode igniter (part number LH33WZ008), factory-specified for the Carrier PY1PNA024040ACBA packaged unit. The spark electrode igniter is a critical component in the gas ignition sequence: after the draft inducer clears the heat exchanger, the igniter fires to ignite the main burners and initiate heat delivery. When this part fails, the furnace or packaged unit will attempt ignition, fail to establish a flame, and lock out — leaving you with no heat and a blinking fault code. A cracked ceramic insulator, fouled electrode tip, or broken ignition wire are the most common failure signatures.

• OEM Part Number: LH33WZ008 | Carrier-branded Spark Electrode Igniter | Factory-direct replacement — no modifications required

• Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: flat-head and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Handle the ceramic electrode carefully — it is fragile. Photograph all wiring connections before disconnecting the ignition wire harness.
