OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9UAA042080AASA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG9UAA042080AASA packaged gas unit. During every call for heat, the control board energizes this igniter to glow at temperatures exceeding 1,800°F, igniting the gas burner within seconds. When it fails — whether from age, thermal shock, or hairline cracks in the element — the furnace will attempt ignition, fail to light, and go into hard lockout, leaving you with no heat. Symptoms include a unit that cycles on, attempts to ignite, then shuts down after 30–90 seconds with a fault code indicating ignition failure.

  • Specs: 120V AC input | Silicon nitride element | Factory OEM tolerances | Replaces part number LH33ZG001 | Approx. 0.07 lbs
  • OEM vs Generic: This is a genuine Carrier OEM igniter, engineered to the exact thermal mass and resistance profile of the original. Generic aftermarket igniters often feature mismatched resistance curves that cause nuisance lockouts or premature failure — the OEM unit is always the safest, longest-lasting choice.
  • Install Difficulty: 2/5 — Shut off power and gas before servicing. Do not touch the silicon nitride element with bare hands — skin oils cause premature failure at ignition temperatures. Tools needed: ¼" nut driver, needle-nose pliers, work gloves. Photograph wiring harness before disconnecting. Typical replacement time: 20–30 minutes.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier PG9UAA042080AASA packaged gas units. Verify part number LH33ZG001 on your unit's parts list or data plate before ordering.

Frequently Asked Questions

Does this Igniter fit my Carrier PG9UAA042080AASA?
Yes. This is the factory-specified OEM igniter for the Carrier PG9UAA042080AASA. 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 PG9UAA042080AASA?
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.
