OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY3PPA042090NA

This OEM spark electrode ignitor assembly is the factory-specified replacement part for the Carrier PY3PPA042090NA packaged gas unit. The ignitor assembly generates the high-voltage spark that ignites the burner on each heating cycle. When this component fails, the furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common symptoms include a clicking sound with no flame establishment, repeated short cycling, or a steady lockout fault code on the control board.

  • Part Number: 48GS400168 | 2-rod spark electrode ignitor assembly | Factory-matched OEM specification | Lightweight design at approximately 0.07 lbs
  • OEM vs Generic: This is a genuine Carrier OEM ignitor assembly, ensuring exact electrode gap, ceramic insulator grade, and lead wire length. Aftermarket igniters frequently have inconsistent electrode geometry that causes misfires and premature control board faults.
  • Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Photograph existing wiring and electrode positioning before removal. Reconnect leads to matching terminals and verify spark gap before restoring power.
  • Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Directly replaces the OEM spark electrode ignitor on Carrier model PY3PPA042090NA packaged gas heating/cooling units. Always verify your existing part number on the unit's data plate or wiring diagram before ordering. Our fitment team is available to confirm compatibility before you buy — same-day shipping on all in-stock orders.

Frequently Asked Questions

Does this Igniter fit my Carrier PY3PPA042090NA?
Yes. This is the factory-specified OEM igniter for the Carrier PY3PPA042090NA. 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 PY3PPA042090NA?
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.
