OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY3GNAA60090AA

This is the genuine OEM factory-specified spark electrode ignitor assembly for the Carrier PY3GNAA60090AA packaged gas unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner at the start of every heat cycle. When this component fails or degrades, the unit will attempt ignition, fail to establish a flame, and lock out — leaving you with no heat and a blinking fault code on the control board. This OEM part includes both the ignitor electrode rods and the mounting bracket, ensuring a direct, no-modification installation.

• Specs: Spark electrode ignitor assembly | Dual-rod ceramic electrode design with mounting bracket | OEM Part # 48VL400002 (superseded by 50HJ403022) | Genuine Carrier Factory Authorized Part
• OEM vs Generic: OEM electrodes are precision-gapped and ceramic-bodied to factory tolerances, ensuring consistent spark at correct voltage. Aftermarket electrodes may ship with incorrect gap spacing, leading to unreliable ignition, nuisance lockouts, and premature failure of the control board ignition circuit.
• Install difficulty: 2/5 — Shut off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" or 5/16" nut driver, flathead screwdriver, needle-nose pliers. Disconnect ignition wire leads, unbolt the bracket, swap the assembly, and reconnect leads. Always verify correct electrode gap per unit service literature before restoring power.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.
