OEM Carrier Spark Electrode Ignitor (48VL400002 / 50HJ403022) for Model PY4GPAB48115AA

This OEM Carrier spark electrode ignitor is the factory-specified replacement for the Carrier PY4GPAB48115AA packaged gas unit. The ignitor generates the high-voltage spark that ignites the gas burner on every call for heat. When this component fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with a blower running but no heat output. A failed ignitor is one of the most common causes of a no-heat service call on Carrier packaged rooftop and gas-electric units.

  • Part Numbers: OEM part 48VL400002 (Spark Electrode Ignitor) | Current OEM successor: 50HJ403022 — direct factory replacement, same fit and function
  • OEM vs Generic: Factory OEM igniters are manufactured to exact electrode gap, ceramic insulator grade, and wire harness specifications. Off-brand substitutes frequently exhibit inconsistent spark timing and premature ceramic cracking, leading to repeat service calls.
  • Install Difficulty: 2/5 — Shut off gas supply and 120V power before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph all wire connections before disconnecting. Avoid touching the ceramic electrode body with bare hands — skin oils accelerate cracking under heat cycling.
  • Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY4GPAB48115AA gas-electric packaged unit. Note that OEM part number 48VL400002 has been superseded by Carrier part 50HJ403022 — both numbers are fulfilled with the current production ignitor assembly. Verify your unit's model and data plate before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Igniter fit my Carrier PY4GPAB48115AA?
Yes. This is the factory-specified OEM igniter for the Carrier PY4GPAB48115AA. 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 PY4GPAB48115AA?
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?
