The igniter is a critical component in the furnace ignition sequence — it heats to over 2,000°F to ignite the gas flowing from the burner assembly. When it fails, the control board will attempt ignition, detect no flame via the flame sensor, and lock the furnace out — leaving you with no heat. A cracked, broken, or open-circuit igniter is one of the most common causes of furnace no-heat service calls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number LH33ZG001 | Silicon nitride element | Factory-rated voltage and wattage | Exact OEM geometry for drop-in fit on PG9MAB036040AASA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM igniter — factory-matched element material, bracket dimensions, and lead-wire length.

Tools needed: 1\/4\" nut driver, needle-nose pliers. Always disconnect power at the breaker before starting.
