OEM Carrier Hot Surface Spark Electrode Igniter for Model PY3PPA030040NA

This is the factory OEM replacement spark electrode igniter (part #48GS400168) for the Carrier PY3PPA030040NA packaged unit. The hot surface igniter is the critical component responsible for lighting the burner on every heating call. When it fails — whether from a hairline crack, oxidation, or open circuit — the control board will attempt ignition, fail to prove flame, and lock out the system, leaving you with a no-heat call. Replacing with the correct OEM part ensures factory-matched electrical resistance, proper glow temperature, and precise positioning in the burner assembly.

• Specs: OEM Part # 48GS400168 | Spark electrode igniter type | Factory-matched resistance and geometry | Designed for Carrier PY3PPA030040NA packaged unit
• OEM vs Generic: OEM igniters are manufactured to exact factory resistance tolerances, ensuring reliable ignition cycle after cycle. Generic or off-brand igniters frequently exhibit resistance drift and premature cracking, leading to repeat failures and unnecessary service calls.
• Install difficulty: 2/5 — Always disconnect power and shut off gas before servicing. Tools needed: ¼" nut driver, flat-blade screwdriver, multimeter (to confirm open circuit on old igniter). Handle new igniter with care — skin oils can cause premature failure; use gloves or clean cloth.
