OEM Carrier Spark Electrode Ignitor Assembly (48VL400002 / 50HJ403022) for Model PY4GPAB48115NA

This OEM Carrier spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY4GPAB48115NA packaged gas unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner at the start of every heat cycle. When it fails, the control board will attempt ignition, fail to detect flame, and lock out the system — leaving you with no heat and a blinking fault code. Note: OEM part number 48VL400002 has been superseded by the current production part 50HJ403022; both part numbers are fulfilled by the same factory-replacement assembly.

• Specs: 2-rod spark electrode design with mounting bracket | Ceramic-insulated electrode body rated for high-temperature operation | Approx. dimensions: 4.25″ L × 2.95″ W × 1.75″ H | Replaces: 48VL400002, 50HJ401430, 50HJ400608
• OEM vs Generic: This is a genuine OEM Carrier ignitor assembly built to exact factory electrode gap and ceramic grade specifications. Generic igniters frequently use inferior ceramic compounds that crack under thermal cycling, causing repeat no-heat calls within one season.
• Install difficulty: 2/5 — Shut off gas supply and 24V control power before beginning. Tools needed: 1/4″ nut driver, needle-nose pliers, and a flashlight. Photograph the existing electrode orientation and wire routing before removal. Do not touch the ceramic electrode body with bare hands — skin oils cause premature cracking.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
