OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB048100AASA

This is the OEM factory-specified hot surface igniter (part number LH33ZG001) for the Carrier PG9MAB048100AASA packaged gas unit. The igniter is the first component called into action on every heating cycle — the control board energizes it to reach ignition temperature, and then the gas valve opens for burner light-off. When this part fails, the furnace will attempt ignition, fail to light the burners, and go into safety lockout — leaving you with no heat. Common symptoms include the unit cycling on and then shutting off after 30–90 seconds, or a fault code indicating an ignition failure on the control board.

  • Part Number & Specs: OEM Part # LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Lightweight 0.07 lb component | Factory-matched plug connector for drop-in installation
  • OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory tolerances. Generic igniters may differ in element geometry, wattage draw, or connector type — all of which can cause nuisance lockouts or premature failure. OEM is always the recommended choice for reliable, long-term performance.
  • Install Difficulty: 3/5 — De-energize the unit at the disconnect and wait for the igniter to fully cool before removal (it retains heat). Never touch the element with bare hands — skin oils will cause hot spots and crack the element. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the harness plug, remove the mounting screw, and reverse for installation. Verify ignition sequence on first call for heat.
  • Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse. Questions about fitment? Our HVAC parts team verifies compatibility before you order.

Compatibility: Designed for the Carrier PG9MAB048100AASA packaged gas/electric unit. Always verify the part number against your unit's parts list or data plate before ordering. If you are unsure whether this igniter matches your specific serial number range, contact our team for a free fitment check.

Frequently Asked Questions

Does this Igniter fit my Carrier PG9MAB048100AASA?
Yes. This is the factory-specified OEM igniter for the Carrier PG9MAB048100AASA. 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 PG9MAB048100AASA?
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.
