OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB060140ACSA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG9MAB060140ACSA gas furnace. The igniter is a critical component in the ignition sequence — it heats to over 2,000°F to ignite the gas at the burner. When it fails, the furnace control board will attempt ignition, find no flame, and lock out — leaving you with no heat and often a blinking fault code indicating an ignition failure.
