OEM Carrier Spark Electrode Ignitor Assembly (50HJ403022) for Model PY1RPA120224ABWB

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY1RPA120224ABWB packaged gas heating system. The ignitor is the first active component in every furnace startup cycle — it generates the spark or surface heat needed to light the burner. When the ignitor fails, the control board will attempt ignition, sense no flame, and lock out the system, leaving you with a furnace that runs the inducer but produces no heat. Common failure symptoms include a hard lockout after 2–3 ignition attempts, an error code indicating ignition failure, or a visually cracked/broken ignitor element.

• Part Number: 50HJ403022 | Also replaces: 48VL400002 | Genuine Carrier OEM factory part
• Construction: Durable ceramic body rated for high-temperature cycling | Includes ignitor element and mounting bracket — complete assembly, no separate hardware required | Approximate dimensions: 4.25″ L × 2.95″ W × 1.75″ H
• OEM vs Generic: OEM ignitors are matched to the exact spark gap, electrode geometry, and ceramic grade specified by Carrier engineering. Generic substitutes may produce inconsistent spark timing, leading to repeat lockouts or premature failure under thermal stress.
• Install Difficulty: 2/5 — Shut off gas supply and 120V power at the disconnect before starting. Tools needed: 1/4″ nut driver, needle-nose pliers. Do NOT touch the ceramic element with bare hands — skin oils accelerate cracking at operating temperatures. Photograph wiring orientation before disconnecting. Typical tech time: 20–30 minutes.
• Warranty: 1-year OEM factory warranty against defects. In-stock orders ship same business day from our warehouse.
