OEM Carrier Hot Surface Ignitor (LH33ZS004 / 329491-401) for Model PG9MAA048080AFKA

This is the genuine OEM hot surface ignitor for the Carrier PG9MAA048080AFKA gas furnace. The ignitor is the first component activated during every heating cycle — the integrated furnace control board energizes it to glow red-hot, igniting the gas burner within seconds. When it fails, the furnace typically completes its inducer pre-purge, then locks out after one or two failed ignition attempts, leaving you with no heat. Common symptoms include a furnace that starts but never fires, an error code for ignition failure, or a visibly cracked or broken ignitor element.

  • Part Numbers: OEM Part LH33ZS004 (Hot Surface Ignitor) | Cross-reference 329491-401 (Gasket Ignitor kit) | Also replaces LH33ZS001, LH33ZS002, LH33ZS003, and 41-409
  • Specs: Silicon carbide flat-style element | 120V AC input | Steady-state current 2.7A–3.9A | Cold resistance 40–200 Ω | Max working temperature 2,650°F | Wide ceramic block style (2" wide) with OEM plug connector
  • OEM vs Generic: This is the factory-matched Carrier ignitor, built to exact resistance and geometry tolerances. Generic igniters often run outside ±10% resistance spec, causing nuisance lockouts, premature failure, or improper flame establishment — especially on tighter-sequenced controls like the PG9MAA series.
  • Install Difficulty: 2/5 — Power down and lock out the furnace before starting. Do not touch the silicon carbide element — skin oils cause premature failure. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Simply unplug the OEM harness connector, remove the single mounting screw, swap the ignitor, and reinstall. Verify ignition sequence on first call for heat.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAA048080AFKA gas furnace. Also cross-compatible with Bryant, Payne, and Day & Night furnaces specifying part number LH33ZS004. Verify your existing ignitor's element style (wide flat ceramic block) and connector type before ordering. Questions about fitment? Our HVAC parts specialists confirm compatibility before you buy — no guesswork.

Frequently Asked Questions

Does this Igniter fit my Carrier PG9MAA048080AFKA — LH33ZS004?
Yes. This is the factory-specified OEM igniter for the Carrier PG9MAA048080AFKA — LH33ZS004. 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 PG9MAA048080AFKA — LH33ZS004?
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?
