OEM Carrier Spark Electrode Ignitor LH33WZ008 for Model PY1PNA024060ADBA

This is the factory OEM spark electrode ignitor for the Carrier PY1PNA024060ADBA packaged unit. The ignitor is a critical component in the gas ignition sequence: after the draft inducer clears the heat exchanger, the ignitor energizes and must reach proper ignition temperature before the gas valve opens. When the electrode fails, the control board will attempt ignition up to three times and then lock out the system entirely — leaving you with no heat until the part is replaced and power is cycled. Common failure symptoms include repeated ignition attempts with no burner light-off, a hard lockout fault code, or a visibly cracked or broken electrode tip.

• OEM Part Number: LH33WZ008 | Carrier-branded spark electrode ignitor | Factory-direct replacement, exact fit for PY1PNA024060ADBA
• OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM igniters are manufactured to exact resistance and geometry tolerances, ensuring reliable light-off and full compatibility with the unit's control board timing sequence. Generic electrodes can cause nuisance lockouts due to off-spec tip positioning or incorrect resistance values.
• Install Difficulty: 2/5 — Shut off gas and electrical power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to confirm electrode resistance. Handle the electrode body only — skin oils on the ceramic insulator can cause premature cracking under heat. Photograph all wiring connections before disconnecting.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.
