OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNAA48115AA

This is the OEM factory-specified spark electrode ignitor for the Carrier PY3GNAA48115AA packaged gas unit. The spark electrode ignitor generates the high-voltage spark that ignites the burner assembly during each heating cycle. When this component fails, the control board will attempt ignition, fail to sense a flame, and lock out the system — leaving you with a unit that blows cold air or no air at all. Fault codes for ignition failure are a telltale sign this part needs replacement.

  • OEM Part Numbers: 48VL400002 (original) | Direct OEM replacement: 50HJ403022 — same factory-spec electrode, updated part number. Ships as current production replacement.
  • OEM vs Generic: OEM Carrier spark electrodes are precision-gapped and rated for the exact spark energy output required by the PY3GNAA48115AA burner assembly. Generic electrodes with improper gap spacing cause repeated ignition misfires, accelerated control board wear, and nuisance lockouts.
  • Install Difficulty: 2/5 — Turn off gas supply and disconnect power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Handle the ceramic electrode body carefully — do not touch the tip or drop the assembly. Document wire routing before disconnecting ignition leads.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered specifically for the Carrier PY3GNAA48115AA packaged gas/electric rooftop unit. OEM part number 48VL400002 has been superseded by 50HJ403022 — both numbers are cross-referenced and the current replacement ships under the updated part number. Verify your model data plate and existing ignitor configuration before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Igniter fit my Carrier PY3GNAA48115AA?
Yes. This is the factory-specified OEM igniter for the Carrier PY3GNAA48115AA. 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 PY3GNAA48115AA?
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?
