OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB036060AASA

This is the genuine OEM Carrier hot surface igniter (part number LH33ZG001), the factory-specified ignition component for the Carrier PG9MAB036060AASA packaged gas unit. During a call for heat, the control board energizes the igniter, which heats to ignition temperature and lights the gas burner. When the igniter fails — whether from age, thermal shock, or hairline cracking — the furnace will attempt ignition, fail to establish flame, and lock out. You'll typically see a no-heat call with the unit cycling through ignition attempts before going into lockout fault.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes mounting bracket and wiring harness | Factory-matched fit for Carrier PG9MAB036060AASA
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact resistance and thermal cycling specifications. Aftermarket igniters frequently use lower-grade silicon carbide elements that run hotter, crack sooner, and can cause nuisance lockouts — costing more in repeat service calls than the price difference saves.
• Install difficulty: 2/5 — De-energize the unit at the disconnect before starting. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, needle-nose pliers. Photograph existing wiring before disconnecting. Verify ignition sequence completes on first call after install.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
