OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNA030040NA

This OEM spark electrode ignitor (part number 48VL400002) is the factory-specified ignition component for the Carrier PY3GNA030040NA packaged gas unit. The spark electrode generates the high-voltage arc that ignites the gas burner at the start of each heating cycle. When this component fails or degrades, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a fault code on the board. Common symptoms include repeated ignition attempts with no flame establishment, intermittent no-heat calls, or a visible crack/carbon tracking on the electrode tip.

• Part Number: 48VL400002 | Superseded by OEM part 50HJ403022 | Factory Authorized Parts designation | Genuine Carrier OEM assembly
• OEM vs Generic: OEM electrodes are gap-set and geometry-matched at the factory for precise spark placement at the burner port. Aftermarket electrodes may have incorrect gap spacing or mounting angle, leading to unreliable ignition and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect the ignition wire carefully — ceramic insulators are fragile and can crack if forced. Always verify spark gap matches OEM spec before firing.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PY3GNA030040NA packaged gas/electric unit. Note that OEM part 48VL400002 has been superseded by Carrier part 50HJ403022 — both are stocked. Verify your unit's data plate and existing electrode mounting configuration before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy.
