OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PEB048115AB

This is the genuine OEM spark electrode ignitor assembly (part# 48GS400168), factory-specified for the Carrier PY2PEB048115AB packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that lights the burners during each heating cycle. When this component 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. Replacing with the correct OEM assembly ensures proper spark gap geometry, correct electrode rod positioning, and reliable first-try ignition every cycle.

• Part Type: 2-Rod Spark Electrode Ignitor Assembly | OEM Part# 48GS400168 | Factory-matched for Carrier packaged HVAC systems
• OEM vs Generic: OEM electrode assemblies are manufactured to exact spark gap and ceramic insulator specifications. Generic igniters frequently use off-spec rod spacing, causing misfires, delayed ignition, or repeat lockouts that damage the heat exchanger over time.
• Install Difficulty: 2/5 — Shut off gas and disconnect power before starting. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Disconnect the high-voltage ignition cable, remove the mounting screws, swap the assembly, and reconnect. Always verify spark gap per the unit's service label before re-firing.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
