OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA048080ABKA

This is the factory OEM hot surface igniter for the Carrier PG9MAA048080ABKA gas furnace. The igniter is a critical component in the heating sequence — it heats to over 1,800°F to ignite the gas burners on each call for heat. When it fails, the furnace will attempt ignition, fail to light the burners, and enter a safety lockout — leaving you with no heat. A cracked, burned-out, or weak igniter is one of the most common causes of furnace no-heat service calls, and replacing it with the correct OEM part ensures reliable, factory-matched performance.

• Specs: OEM Part Number LH33ZS004 | Silicon nitride hot surface igniter | Factory-matched voltage and wattage rating | Designed for 80% AFUE gas furnace applications
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact specifications for resistance, wattage draw, and thermal cycling durability. Generic igniters often use lower-grade silicon carbide materials that are more brittle, crack sooner under thermal stress, and can cause repeat service calls within the same heating season.
• Install Difficulty: 2/5 — Disconnect power and gas before servicing. Tools needed: 1/4" nut driver or hex driver, needle-nose pliers, and work gloves. Do not touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Photograph wiring before disconnecting. Average replacement time: 20–30 minutes.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
