OEM Carrier Spark Electrode Ignitor LH33WZ008 for Model PY1PPA048120AFBA

This is the genuine OEM Carrier spark electrode ignitor (part number LH33WZ008), factory-specified for the Carrier PY1PPA048120AFBA packaged unit. The ignitor is the first active component in the heating sequence — after the draft inducer proves airflow, the ignitor energizes and must reach ignition temperature before the gas valve opens. When the ignitor fails or cracks, the control board detects no successful ignition and locks the unit out, typically after 3 attempts. The result: a system that calls for heat but delivers none.

• Part Number: LH33WZ008 | OEM Carrier Spark Electrode Ignitor | Factory-direct replacement, no modifications required
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory specifications. Generic igniters vary in electrode gap, ceramic composition, and wire harness length — any deviation can cause intermittent ignition failure or premature cracking. OEM is the only reliable choice for this application.
• Install Difficulty: 3/5 — The ignitor element is extremely fragile; never touch the ceramic tip with bare hands. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify continuity before installation. Disconnect power and gas before beginning. Photograph all wire connections prior to removal.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered by cutoff time.
