OEM Carrier Spark Electrode Igniter LH33WZ008 for Model PY1PNA036100ADBA

This is the factory OEM spark electrode igniter (part number LH33WZ008) for the Carrier PY1PNA036100ADBA packaged unit. The spark electrode igniter is responsible for initiating combustion at the main burners during each heating cycle. When this component fails, the control board will attempt ignition — typically two to three times — and then lock out the system entirely, leaving you with no heat. Common symptoms include a furnace that clicks but fails to light, a system that locks out after the inducer runs, or a visually cracked or broken electrode tip discovered during inspection.

• Part Number: LH33WZ008 | OEM Carrier Spark Electrode Igniter | Factory-direct replacement — no modifications required
• OEM vs Generic: This is a genuine OEM Carrier part, manufactured to exact factory tolerances for spark gap, ceramic insulation rating, and lead wire length. Aftermarket electrodes frequently suffer from improper spark gap or inferior ceramic that cracks under thermal cycling, causing repeat failures.
• Install Difficulty: 2/5 — Shut off gas and power before starting. Tools needed: 1/4" nut driver, needle-nose pliers. Photograph or label the igniter wire connector before removal. Handle the ceramic insulator carefully — do not touch the electrode tip with bare hands, as skin oils can cause premature failure. Reinstall bracket screws to snug, not overtight.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
