OEM Carrier Spark Electrode Ignitor Assembly 50HJ403022 for Model PY1RPA120180ABWB

This is the genuine OEM spark electrode ignitor assembly (part number 50HJ403022), factory-specified for the Carrier PY1RPA120180ABWB gas-fired HVAC system. The ignitor is the first critical component in the furnace heating sequence — it generates the spark or surface heat required to light the burner. When it fails, the system will attempt ignition, fail to establish flame, and enter a safety lockout, leaving you with no heat. Common symptoms include the furnace cycling on the inducer motor but never producing heat, a blinking fault code for ignition failure, or the unit locking out after 3 consecutive failed ignition attempts.

• Part Specs: OEM Carrier spark electrode ignitor assembly | Part No. 50HJ403022 | Replaces 48VL400002 | Approx. 4.25″ L × 2.95″ W × 1.75″ H | ~0.095 lb | Ceramic body construction | Supplied without wire harness
• OEM vs. Generic: This is a genuine Carrier-manufactured assembly built to exact factory tolerances. OEM igniters are precision-matched to the burner geometry and gas valve timing of your specific unit. Aftermarket substitutes may have inconsistent electrode gap or inferior ceramic materials, leading to premature failure or nuisance lockouts.
• Install Difficulty: 2/5 — Straightforward swap for an experienced DIYer or technician. Tools needed: 1/4″ nut driver, needle-nose pliers. Always shut off gas supply and 24V control power before starting. Do not touch the ceramic ignitor element with bare hands — skin oils cause hot spots and cracking. Photograph the original wiring orientation before disconnecting.
• Warranty & Shipping: Backed by Carrier's 1-year OEM parts warranty. In stock and ships same business day from our warehouse when ordered before cutoff.
