OEM Carrier Hot Surface Igniter for Model PY3PNA024040AA — Part # 48GS400168

This is the genuine OEM hot surface igniter for the Carrier PY3PNA024040AA packaged unit. The igniter is a critical component in the gas heating sequence — it reaches extreme temperatures within seconds to ignite the gas burner. When it fails, the furnace or packaged unit will attempt ignition, fail to light, and enter a safety lockout, leaving you with no heat and a blinking fault code. Replacing with the factory OEM part (48GS400168) ensures the correct wattage, resistance, and physical fit for a reliable, long-lasting repair.

  • Specs: Part Number 48GS400168 | Spark Electrode / Hot Surface Igniter | Factory-matched wattage and resistance for Carrier PY3PNA024040AA | Durable high-temperature ceramic body
  • OEM vs Generic: OEM igniters are manufactured to exact wattage and resistance tolerances required by the control board. Generic igniters frequently fall outside spec, causing nuisance lockouts, premature cracking, or failure to reach ignition temperature — always choose OEM for safety-critical ignition components.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, work gloves (never touch the igniter element with bare hands — skin oils cause premature failure). Photograph wiring and orientation before removal.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as a direct OEM replacement for Carrier model PY3PNA024040AA packaged units. Always verify the part number on your existing igniter or your unit's wiring diagram before ordering. Need help confirming fitment? Our HVAC parts specialists verify compatibility before you buy — contact us today.

How do I replace the igniter on my Carrier PY3PNA024040AA — 48GS400168?
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.
