OEM Carrier Hot Surface Igniter (48GS400168) for Model PY3PEA048115NB

This OEM spark electrode igniter is the factory-specified replacement for the Carrier PY3PEA048115NB packaged unit. The hot surface igniter is responsible for generating the high-temperature spark that ignites the burner assembly on each heating call. When it fails, the control board will attempt ignition, detect no flame, and enter a hard lockout — leaving you with a system that calls for heat but delivers none. Common failure symptoms include a no-heat condition, repeated ignition attempts followed by lockout, or a visibly cracked/broken igniter element.

• Specs: OEM Part Number 48GS400168 | Type: Spark Electrode Ignitor | Factory-matched fit and electrical specifications for Carrier PY3PEA048115NB packaged units | Rated for reliable ignition across full burner duty cycle
• OEM vs Generic: This is a genuine OEM Carrier igniter, manufactured to exact factory tolerances for element temperature, electrode gap, and mounting geometry. Generic igniters can exhibit premature cracking, mismatched resistance, and inconsistent spark timing — all of which shorten system life and risk nuisance lockouts.
• Install Difficulty: 3/5 — Requires shutting off gas supply and disconnecting power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (to verify resistance). Handle igniter element with care — skin oils can cause premature cracking. Always confirm gas is off and capacitors are discharged before beginning work.
