OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GEAB60115AA

This OEM spark electrode ignitor (part number 48VL400002, superseded by 50HJ403022) is the factory-specified replacement for the Carrier PY4GEAB60115AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage arc that ignites the gas burner on every call for heat. When it fails, the control board will attempt ignition, find no flame established, and lock out the system — leaving you with a blinking fault code and no heat. Replacing the ignitor is one of the most common and cost-effective furnace repairs available.

• OEM Part Numbers: 48VL400002 (original) | Superseded by 50HJ403022 — both are factory-authorized Carrier components and direct functional replacements for this model.
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, engineered to exact spark gap and electrode geometry specifications for the PY4GEAB60115AA burner assembly. Aftermarket electrodes often have inconsistent gap tolerances, leading to intermittent ignition failures or premature ceramic cracking.
• Install Difficulty: 2/5 — Turn off gas supply and 24V power at the disconnect before starting. Tools needed: 1/4" nut driver, needle-nose pliers, work light. Note wire harness routing and connector orientation before disconnecting. Handle the ceramic electrode tip carefully — do not drop or squeeze. Verify spark gap per unit service manual before reinstalling burner access panel.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed before our same-day cutoff ship from our warehouse today.
