OEM Carrier Spark Electrode Ignitor for Model PY4GPAA48115AA (48VL400002 / 50HJ403022)

This OEM Carrier spark electrode ignitor is the factory-specified replacement for the Carrier PY4GPAA48115AA packaged gas/electric unit. The spark electrode ignitor is a critical component in the ignition sequence: on every call for heat, the control board energizes the ignitor to generate a high-voltage spark that lights the burner assembly. When this part fails, the unit will attempt ignition, fail to establish flame, and enter a safety lockout — leaving your space without heat. Common symptoms include a single audible click with no ignition, repeated ignition attempts followed by lockout, or an error code indicating ignition failure.

  • OEM Part Numbers: 48VL400002 (original) | 50HJ403022 (current OEM replacement) — both are factory-authorized Carrier parts for this unit
  • OEM vs Generic: OEM igniters are manufactured to Carrier's exact electrode gap, ceramic insulator rating, and cable specifications. Off-brand electrodes frequently exhibit inconsistent spark gap tolerances, premature ceramic cracking, and incompatible connector terminations that can cause intermittent lockouts and shorten ignition module life.
  • Install Difficulty: 2/5 — Shut off gas supply and disconnect power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note electrode gap and cable routing before removal. Do not touch the ceramic insulator body — skin oils accelerate cracking under heat. Typical service time: 20–30 minutes.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered by cutoff time.

Compatibility: Engineered for the Carrier PY4GPAA48115AA packaged gas/electric rooftop unit. OEM part number 48VL400002 has been superseded by Carrier OEM part 50HJ403022 — both are stocked and ship the same day. Verify your unit's data plate and existing ignitor connector style before ordering. Our technical team is available to confirm fitment before you buy.

Frequently Asked Questions

Does this Igniter fit my Carrier PY4GPAA48115AA — 48VL400002?
Yes. This is the factory-specified OEM igniter for the Carrier PY4GPAA48115AA — 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 PY4GPAA48115AA — 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?
