The igniter is a critical component in the ignition sequence — it heats to over 2,000°F to light the burner assembly each heating cycle. When it fails, the control board will attempt ignition, detect no flame, and lock out the furnace, leaving you with a blinking fault code and no heat. Common symptoms include the furnace cycling on, attempting to light, then shutting down completely after 3 attempts with a lockout code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number LH33ZS004 | Silicon nitride hot surface igniter | Factory-matched resistance and geometry for Carrier PG9MAA060120ADKA | 120V operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the exact factory-grade igniter matched to Carrier's tolerance specifications.
