OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PPB042090NB

This is the factory-authorized OEM spark electrode ignitor (part number 48GS400168) for the Carrier PY2PPB042090NB packaged gas unit. The ignitor is the first link in your heating sequence: on a call for heat, the control board energizes the ignitor to generate a spark that lights the burners. When it fails, the unit will attempt ignition, fail to establish flame, and enter a hard lockout — leaving you with a no-heat condition. Common symptoms include repeated ignition attempts with no burner light-off, an error code indicating ignition failure, or a visibly cracked or carbon-fouled electrode tip.

• Part Number: 48GS400168 | OEM Carrier Factory Authorized Parts | Spark electrode (2-rod) ignitor assembly | Direct drop-in replacement — no modifications required
• OEM vs Generic: OEM igniters are manufactured to exact factory electrode gap and ceramic insulator specifications. Aftermarket substitutes frequently have inconsistent electrode spacing, leading to unreliable spark and repeat lockouts — defeating the purpose of the repair.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Note wire lead polarity and routing before disconnecting. Handle the ceramic insulator carefully — cracks from improper handling will cause immediate failure.
• Warranty: 1-year OEM factory warranty on parts. In-stock and ships same business day from our warehouse.

Compatibility: Engineered specifically for the Carrier PY2PPB042090NB packaged gas/electric unit. Always cross-reference your unit's data plate and existing ignitor part number before ordering to confirm fitment. Our team is available to verify compatibility prior to purchase — don't guess on a heat call.
