OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PPB042090AA

This genuine OEM Carrier spark electrode ignitor (part number 48GS400168) is the factory-specified replacement for the Carrier PY2PPB042090AA packaged gas heating unit. The spark electrode ignitor initiates combustion by generating a high-voltage spark directly at the burner. When this component fails, the unit will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat and a system that won't restart without a manual reset. Replacing the ignitor with the correct OEM part restores reliable, code-compliant ignition performance.

  • Part Number: 48GS400168 | Manufacturer Description: Spark Electrode Ignitor/Electrode Assembly | Factory Authorized Carrier Part
  • OEM vs Generic: This is a genuine OEM Carrier component engineered to exact factory tolerances for the PY2PPB042090AA. Aftermarket electrodes frequently have mismatched gap spacing and lead wire lengths, leading to repeated ignition faults and premature failure.
  • Install Difficulty: 2/5 — Shut off gas and electrical power before beginning. Tools needed: Phillips and flathead screwdrivers, needle-nose pliers, and a multimeter to verify spark output. Photograph all wire connections before disconnecting. Verify electrode gap per unit service manual before reinstalling the burner access panel.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY2PPB042090AA packaged gas/electric unit. This part is also used across multiple Carrier package unit platforms — verify your unit's data plate and existing part number before ordering. Questions about fitment? Our HVAC parts specialists confirm compatibility before your order ships.

Frequently Asked Questions

Does this Igniter fit my Carrier PY2PPB042090AA?
Yes. This is the factory-specified OEM igniter for the Carrier PY2PPB042090AA. 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 PY2PPB042090AA?
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?
