OEM Carrier Hot Surface Igniter 120V with Bracket & Gasket Assembly for Model PG9MAA024040AAKA

This OEM hot surface igniter kit is the factory-specified replacement for the Carrier PG9MAA024040AAKA gas furnace. It includes the primary igniter element (LH33ZS004) and the igniter bracket and gasket assembly (323901-701), ensuring a complete, leak-free installation. The hot surface igniter heats to over 1,800°F within seconds to ignite the gas burners on every call for heat. When the igniter fails, the furnace control board will detect a failed ignition attempt and lock out — leaving you with no heat and a flashing fault code. Replacing both the igniter and gasket together eliminates the two most common points of failure in a single service call.

• Specs: 120V AC input | 5-amp draw | Silicon nitride element | Includes OEM mounting bracket (323901-701) with integrated burner gasket | Factory-matched geometry for drop-in fit on Carrier PG9MAA024040AAKA
• OEM vs Generic: OEM silicon nitride igniters are precision-rated for exact resistance and temperature ramp. Off-brand igniters frequently exceed resistance tolerances, causing nuisance lockouts or premature failure within one heating season.
• Install difficulty: 2/5 — Turn off gas and disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, work gloves (never touch the igniter element with bare hands — skin oils cause hot spots and cracking). Swap bracket gasket at the same time to prevent flue gas leaks. Verify ignition sequence after reinstall.
• Warranty: 1-year OEM factory warranty on both components. In-stock and ships same business day from our warehouse.
