OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA048100ABKA

This is the genuine OEM hot surface igniter for the Carrier PG9MAA048100ABKA gas furnace. The igniter is the first component to activate on every call for heat — it glows to ignition temperature within seconds, lighting the burner to start your heating cycle. When it fails, the furnace control board will detect a missed ignition event and lock out the system, leaving you with no heat. Classic symptoms include a furnace that attempts to start, clicks through the ignition sequence, then shuts down after 30–90 seconds with a fault code.

  • Specs: 120V AC | 5 Amp | Silicon carbide hot surface igniter | Factory OEM part number LH33ZS004 | Direct drop-in replacement — no modification required
  • OEM vs Generic: OEM igniters are manufactured to Carrier's exact resistance and thermal cycling tolerances. Generic igniters frequently vary in tip geometry and resistance, leading to intermittent ignition failures or premature cracking of the fragile element.
  • Install difficulty: 2/5 — Turn off power and gas before starting. Tools needed: 1/4" nut driver, needle-nose pliers. CAUTION: Never touch the ceramic element with bare hands — skin oils cause hot spots that crack the igniter. Photograph the wiring harness before disconnecting. Total job time is typically under 15 minutes.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.

Compatibility: Factory-specified replacement for the Carrier PG9MAA048100ABKA gas furnace. Also cross-references with earlier Carrier igniter part numbers LH33ZS003, LH33ZS002, and LH33ZS001 for qualifying models. Always verify your furnace model data plate and existing part number before ordering. Our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Igniter fit my Carrier PG9MAA048100ABKA?
Yes. This is the factory-specified OEM igniter for the Carrier PG9MAA048100ABKA. 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 PG9MAA048100ABKA?
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.
