OEM Carrier Spark Electrode Igniter LH33WZ008 for Model PY1PNA048080AEBA

This is the genuine OEM Carrier spark electrode igniter (part number LH33WZ008), the factory-specified replacement for the Carrier PY1PNA048080AEBA packaged gas/electric unit. The igniter is a critical component in the furnace's ignition sequence: after the draft inducer clears the heat exchanger, the igniter receives power, reaches ignition temperature, and triggers the gas valve to open and light the main burners. When this part fails, the furnace will attempt ignition multiple times and then lock out entirely — leaving you with no heat until the component is replaced.

• Part Number: LH33WZ008 | Manufacturer Description: Spark Electrode Ignitor | Genuine OEM Carrier replacement part
• OEM vs Generic: This is a factory-original Carrier igniter engineered to exact dimensional and electrical tolerances for the PY1PNA048080AEBA. Aftermarket alternatives may vary in electrode gap, wire harness length, and bracket fit — risking repeated lockouts or premature failure.
• Install Difficulty: 3/5 — Shut off gas supply and 24V control power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify open-circuit resistance, typically 40–90Ω). Handle the ceramic electrode body carefully — avoid touching it with bare hands, as skin oils can cause cracking under heat. Photograph existing wiring and bracket orientation before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
