OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY3PNA048090AA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3PNA048090AA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner on each heating cycle. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a no-heat call and a flashing fault code on the board. This 2-rod electrode assembly is the correct factory-specified replacement to restore reliable ignition.

• Specs: 2-rod spark electrode assembly | OEM part number 48GS400168 | Lightweight 0.07 lb assembly | Package dimensions: 3.80" × 1.40" × 4.90" | Factory-matched fit for Carrier 48GS-series gas pack systems
• OEM vs Generic: This is the genuine Carrier OEM ignitor assembly — not an aftermarket substitute. OEM electrodes maintain the precise gap geometry and ceramic insulation specs required for consistent spark arc. Generic igniters often suffer from premature ceramic cracking or incorrect gap tolerances, leading to repeat no-heat failures.
• Install difficulty: 2/5 — Shut off gas and disconnect power before servicing. Tools needed: 1/4" hex driver, needle-nose pliers, and a flashlight. Note wire harness routing before disconnecting. Ceramic electrode tip is fragile — handle with care and avoid contact with oils or debris.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
