OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PNB048115AB

This is the genuine OEM spark electrode ignitor assembly (part #48GS400168) factory-specified for the Carrier PY2PNB048115AB packaged gas unit. The 2-rod electrode assembly generates the high-voltage spark that ignites the burner during each heating cycle. When this part fails, the control board attempts ignition, receives no confirmation of flame establishment, and triggers a lockout fault — leaving you with a system that attempts to start but delivers no heat. You may observe repeated ignition attempts followed by a fault code, or a complete no-heat condition from the first call.

• Specs: 2-rod spark electrode ignitor assembly | OEM part #48GS400168 | Lightweight 0.07 lb | Compact form factor (approx. 3.8" × 1.4" × 4.9") | Direct OEM drop-in replacement
• OEM vs Generic: This is a genuine Carrier factory-authorized ignitor assembly. OEM electrodes maintain exact rod spacing and ceramic insulator integrity critical for reliable spark generation. Aftermarket units frequently suffer from gap drift and inferior insulator materials, leading to intermittent ignition failures and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a flashlight. Photograph the existing wiring harness connector orientation before removal. Reconnect leads to matching terminals and verify the electrode rods are positioned correctly over the burner port before restoring power.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.
