OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PNA042090NA

This is the genuine OEM Carrier spark electrode ignitor assembly, part number 48GS400168, factory-specified for the Carrier PY3PNA042090NA packaged unit. The spark electrode ignitor is a critical component in the gas ignition sequence — it generates the high-voltage spark that lights the burner when a call for heat is initiated. When this part fails, the unit will attempt ignition, fail to establish flame, and enter a safety lockout, leaving you with no heat and a fault code on the control board.

  • Part Number: 48GS400168 | OEM Carrier Spark Electrode Ignitor Assembly | Replaces PSE-CE15 | Factory-authorized genuine Carrier part
  • OEM vs Generic: This is a genuine Carrier OEM ignitor — not an aftermarket substitute. OEM electrodes maintain exact spark gap geometry and ceramic insulator ratings, ensuring reliable ignition and preventing nuisance lockouts that poorly toleranced generic parts can cause.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Photograph wiring and electrode position before removal. Handle ceramic insulator carefully to avoid cracking.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier PY3PNA042090NA packaged gas/electric unit. Verify your model and serial number against your unit's data plate before ordering. Not sure it fits? Our parts specialists confirm fitment before you buy — ships fast so your system is back up and running today.

Frequently Asked Questions

Does this Igniter fit my Carrier PY3PNA042090NA?
Yes. This is the factory-specified OEM igniter for the Carrier PY3PNA042090NA. 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 PY3PNA042090NA?
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.
