OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8MAA048110ABJA
This is the genuine OEM Carrier hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8MAA048110ABJA gas furnace. The hot surface igniter is the component that glows red-hot to ignite the gas burners on each heating cycle. When it fails, your furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. This kit upgrades your system to the more durable silicon nitride (Si₃N₄) element, replacing the older silicon carbide igniter (LH33ZS004) found in many 33" tall Carrier furnace models.

OEM vs Generic: This factory-genuine kit is engineered to exact Carrier tolerances. Generic igniters often use lower-grade ceramic blends with wider resistance variance, increasing the risk of premature cracking and nuisance lockouts. The OEM silicon nitride element is significantly more crack-resistant than the original silicon carbide design it replaces.
-
Install Difficulty: 2/5 — This is a straightforward swap suitable for experienced DIYers and technicians alike. Tools needed: ¼" nut driver, needle-nose pliers, voltage tester. Always shut off gas supply and disconnect power before servicing. Allow the old igniter to cool completely before handling — silicon nitride is brittle and must not be touched with bare hands (skin oils cause hot spots and cracking). Use the included bracket and harness for a clean, plug-and-play installation.
-
Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.
Compatibility: Designed for the Carrier PG8MAA048110ABJA gas furnace. Also replaces OEM part number LH33ZS004 in compatible 33" tall Carrier, Bryant, and Payne furnace models.
