OEM Carrier Spark Electrode Ignitor Assembly 50HJ403022 for Model PY1RJA048115AAWA

This is the genuine OEM Carrier spark electrode ignitor assembly (part #50HJ403022) — the factory-specified replacement for the Carrier PY1RJA048115AAWA packaged gas/electric unit. The ignitor assembly initiates combustion each heating cycle by generating the spark that lights the burner. When this component fails, the furnace will attempt ignition, fail to establish flame, and enter a safety lockout — leaving you with no heat. Common symptoms include the unit starting its ignition sequence but shutting down after 30–90 seconds, or a continuous no-heat fault code on the control board.

• Part Type & Specs: Spark electrode ignitor assembly | Ceramic-body construction | Approx. 4.25″ L × 2.95″ W × 1.75″ H | Weighs ~0.095 lb | Includes ignitor element and mounting bracket — no separate hardware required
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances for the PY1RJA048115AAWA. Generic igniters often lack precision electrode gap calibration, leading to unreliable spark, misfires, and premature failure — always choose OEM for critical ignition components.
• Install Difficulty: 3/5 — Always shut off power and gas supply before servicing. Tools needed: 1/4″ nut driver, needle-nose pliers, work gloves (ceramic element is fragile — do not touch with bare hands). Locate the ignitor on the burner assembly, disconnect the plug connector, remove the single mounting screw, and reverse to install. Verify operation through a full heating cycle before closing the cabinet.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse — get your heat back fast.
