OEM Carrier Hot Surface Igniter Kit 331930-751 for Model PG8MAA048135ABJA

This is the factory OEM hot surface igniter replacement kit for the Carrier PG8MAA048135ABJA gas furnace. The hot surface igniter is a critical component in the ignition sequence — it glows to a high temperature to ignite the gas burners on each heating call. When it fails, the furnace control board will attempt ignition, detect no flame, and enter a safety lockout, leaving you with no heat. Common failure symptoms include a furnace that starts the inducer and opens the gas valve but produces no flame, or one that flashes a fault code indicating an ignition failure after 2–3 retries.
