OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY3PEA042090NB

This is the OEM factory-specified spark electrode ignitor assembly for the Carrier PY3PEA042090NB packaged gas unit. The 2-rod ignitor generates the high-voltage spark that ignites the gas burner on each heating call. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a blinking fault code. Replacing this ignitor with the correct OEM part restores reliable spark ignition and prevents nuisance lockouts caused by weak or misdirected spark.

  • Specs: 2-rod spark electrode ignitor assembly | OEM Part# 48GS400168 | Fits Carrier 48GS-series gas pack equipment | Factory-matched electrode gap and bracket geometry
  • OEM vs Generic: This is a genuine Carrier OEM ignitor assembly, engineered to exact gap spacing and rod angle specifications. Generic substitutes often feature incorrect electrode geometry, resulting in weak spark, misfires, and premature control board wear.
  • Install Difficulty: 2/5 — Shut off gas and 24V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note ceramic insulator orientation before removal — cracks in the ceramic during handling will require a new part. Do not touch the electrode rods with bare hands.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PEA042090NB packaged gas/electric unit. Verify your unit's model and serial data plate before ordering to confirm ignitor type. Not sure it fits? Our team verifies fitment before you order — contact us and we'll confirm.

Frequently Asked Questions

Does this Igniter fit my Carrier PY3PEA042090NB?
Yes. This is the factory-specified OEM igniter for the Carrier PY3PEA042090NB. 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 PY3PEA042090NB?
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.
