OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY3PPA048090NB

This is the genuine OEM spark electrode ignitor assembly (part number 48GS400168), factory-specified for the Carrier PY3PPA048090NB packaged gas/electric unit. The ignitor assembly initiates combustion by generating a high-voltage spark across a precisely gapped 2-rod electrode to light the gas burner. When this part fails, the system will attempt ignition, fail to establish flame, and enter a safety lockout — leaving you with no heat. Common failure symptoms include the inducer running normally but burners never lighting, repeated ignition attempt cycles, or a fault code indicating ignition failure on the control board.

  • Part Specs: 2-rod spark electrode design | Factory-spec gap and ceramic insulator | OEM part number 48GS400168 | Designed for 48GS-series gas pack applications
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact electrode gap and ceramic insulator tolerances. Generic igniters often have inconsistent gap spacing and lower-grade ceramics, leading to misfires, premature cracking, and repeat failures — especially in high-cycle commercial or residential packaged units.
  • Install Difficulty: 2/5 — Turn off gas supply and 24V/line-voltage power at the disconnect before starting. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Photograph existing wiring harness routing before disconnecting. Handle ceramic insulator carefully — do not touch electrode tips with bare hands (skin oils reduce spark performance).
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse on all orders placed before cutoff.

Compatibility: Engineered as the direct OEM replacement for Carrier model PY3PPA048090NB packaged units. Always verify your unit's model and serial number against this part number before ordering. Our parts specialists are available to confirm fitment — contact us before you order if you have any questions. Order now and get same-day shipping on in-stock parts.

Frequently Asked Questions

Does this Igniter fit my Carrier PY3PPA048090NB?
Yes. This is the factory-specified OEM igniter for the Carrier PY3PPA048090NB. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the igniter on my Carrier PY3PPA048090NB?
Difficulty: Medium (20–30 min)
Step 1: Turn off power and gas. Step 2: Open furnace panel. Step 3: Locate igniter near burners. Step 4: Disconnect two-wire plug. Step 5: Remove mounting screw. Step 6: Install new igniter — do NOT touch element with fingers. Step 7: Reconnect, close panel, restore power/gas.
My furnace won’t ignite. What part is bad?
Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.
Is this igniter compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier igniter?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
