OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB024060LBSA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG9MAB024060LBSA packaged gas unit. During a call for heat, the control board energizes the igniter, which heats to approximately 2,000°F and ignites the burner flame. When the igniter fails — typically due to age-related cracking, surface contamination, or element burnout — the furnace will attempt ignition, fail to light, and enter a hard lockout condition. The result: no heat, a blinking fault code, and a cold home.

• Specs: 120V AC | Silicon nitride element | OEM part number LH33ZG001 | Includes factory connector harness and mounting bracket | Weight: 0.07–0.10 lbs
• OEM vs Generic: This is a genuine Carrier OEM igniter matched to exact resistance, geometry, and thermal cycling specs for your unit. Generic aftermarket igniters can have inconsistent resistance values, leading to failed ignition sequences or premature cracking — especially in packaged units subject to outdoor thermal stress.
• Install difficulty: 2/5 — De-energize and lockout/tagout the unit before starting. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Do not touch the ceramic element with bare hands — skin oils cause hot spots and premature failure. Photograph existing wiring before disconnecting harness.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PG9MAB024060LBSA packaged gas unit. Always verify your unit's parts list or data plate specifies part number LH33ZG001 before ordering. If your fault code indicates an ignition failure (typically 3 or 4 flashes on Carrier controls), this igniter is the most common root-cause component. Our fitment team is standing by to verify compatibility before you order — no guesswork required.
