OEM Carrier Spark Electrode Ignitor for Model PY3GNAA36090AA (48VL400002 / 50HJ403022)

This OEM Carrier spark electrode ignitor is the factory-authorized replacement for the Carrier PY3GNAA36090AA packaged gas unit. The spark electrode initiates combustion by generating a precisely timed high-voltage spark directly at the burner. When this component fails or degrades, the control board will attempt ignition, find no flame confirmation, and enter a safety lockout — leaving you with a blower running but no heat. Replacing the ignitor is one of the most common and cost-effective furnace repairs available.

  • Specs: Spark electrode ignitor assembly | OEM part 48VL400002, superseded by 50HJ403022 | Also replaces 50HJ401430 and 50HJ400608 | Genuine Carrier factory-authorized part
  • OEM vs Generic: OEM electrodes are manufactured to exact gap tolerances and insulator ratings specified by Carrier engineering. Off-brand electrodes often have inconsistent spark gap geometry, leading to intermittent ignition failures and accelerated control board wear.
  • Install difficulty: 2/5 — Shut off gas supply and 120V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect the ignition wire connector, remove the mounting screws, and swap the electrode. Always verify the spark gap matches OEM spec before reassembling the burner compartment.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Fits Carrier model PY3GNAA36090AA packaged gas heating/cooling unit. Note: Original part number 48VL400002 has been discontinued by Carrier and is fulfilled by the current OEM successor part 50HJ403022. Verify your existing ignitor style and wire harness connector before ordering. Need help confirming fitment?

Frequently Asked Questions

Does this Igniter fit my Carrier PY3GNAA36090AA — 48VL400002?
Yes. This is the factory-specified OEM igniter for the Carrier PY3GNAA36090AA — 48VL400002. 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 PY3GNAA36090AA — 48VL400002?
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?
