OEM Carrier Spark Electrode Ignitor Assembly 50HJ403022 for Model PY1RPA090180ACWB

This is the genuine OEM hot surface igniter assembly (part number 50HJ403022), factory-specified for the Carrier PY1RPA090180ACWB packaged gas/electric unit. The igniter is the first active component in every heating cycle — it heats to extreme temperature to ignite the gas burner. When it fails, the control board typically attempts ignition 3 times before locking out, leaving you with a system that powers on but delivers no heat. Common failure symptoms include a furnace that attempts to start and then shuts down after 30–90 seconds, error codes indicating ignition failure, or a visibly cracked or broken igniter element.

• Specs: Spark electrode ignitor assembly | Ceramic-body construction | Approximately 4.25″ L × 2.95″ W × 1.75″ H | ~0.095 lb | Mounting bracket included | Replaces obsolete part 48VL400002
• OEM vs Generic: This is a genuine Carrier OEM assembly manufactured to exact factory tolerances. Generic igniters frequently differ in element geometry and wattage draw, causing misfires, accelerated cracking under thermal stress, and premature failure — always use OEM on ceramic-tipped spark electrode designs.
• Install Difficulty: 2/5 — Turn off gas supply and 24V power before beginning. Tools needed: 1/4″ nut driver, needle-nose pliers. Carefully transfer wiring connector from old unit — do not touch the ceramic element with bare hands, as skin oils cause hot spots and early failure. Note orientation of bracket before removal.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
