OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY4GEAB60115NA

This OEM Carrier spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY4GEAB60115NA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner on every call for heat. When this component fails, the control board detects a missed ignition event and triggers a safety lockout — leaving you with a system that attempts to start, fails, and shuts down after one to three tries. Replacing the ignitor with a genuine OEM assembly restores the precise spark timing and electrode gap required by the factory burner design.

• Part Number: OEM 48VL400002 | Current OEM replacement: 50HJ403022 | Genuine Carrier Factory Authorized Part | Includes ignitor electrode rods and mounting bracket
• OEM vs Generic: OEM ignitor assemblies maintain the exact electrode gap and ceramic insulator grade specified by Carrier's burner engineering team. Off-brand electrodes may use inferior ceramics that crack under thermal cycling, causing intermittent no-heat calls and repeat service visits.
• Install Difficulty: 2/5 — Shut off gas supply and 24V control power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, wire connector. Disconnect the high-voltage ignitor cable before removing the old assembly. Do not touch the electrode tips with bare hands — skin oils can cause premature ceramic degradation.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Orders placed before 2:00 PM local time ship same business day from our warehouse.

Compatibility: Designed for the Carrier PY4GEAB60115NA packaged rooftop gas/electric unit. OEM part 48VL400002 has been superseded by Carrier part 50HJ403022 — both are fulfilled as the current production ignitor assembly. Verify your model and serial number on the unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
