OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PEA048090NB

This is the factory OEM spark electrode ignitor assembly (part number 48GS400168) for the Carrier PY3PEA048090NB gas packaged unit. The spark electrode ignitor is responsible for initiating ignition of the gas burner on every heating cycle. When this component fails, the control board will attempt ignition, detect no flame, and trigger a safety lockout — leaving you with a system that attempts to start, fails repeatedly, and ultimately shuts down with a fault code. A failed ignitor is one of the most common causes of no-heat calls in packaged gas units.

  • Part Number: 48GS400168 | OEM Carrier Factory Authorized Part | Spark Electrode / Ignitor Assembly | Direct factory-spec replacement — no modifications required
  • OEM vs Generic: This is a genuine Carrier OEM ignitor, factory-matched to the PY3PEA048090NB burner assembly geometry and electrode gap. Generic igniters often have incorrect electrode spacing or incompatible bracket geometry, leading to misfire or premature failure.
  • Install Difficulty: 2/5 — Shut off gas supply and 24V control power before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect ignitor wire harness, remove mounting screws, swap electrode assembly, and reconnect. Always confirm gas is off and the unit is in lockout reset before testing.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PEA048090NB 4-ton 90,000 BTU packaged gas/electric unit. Verify your existing ignitor part number on the unit data plate or wiring diagram before ordering.

Frequently Asked Questions

Does this Igniter fit my Carrier PY3PEA048090NB?
Yes. This is the factory-specified OEM igniter for the Carrier PY3PEA048090NB. 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 PY3PEA048090NB?
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?
