OEM Carrier Hot Surface Igniter Kit 120V — Part #331930-751 for Model PG8JAA066135AAJA

This is the factory OEM hot surface igniter replacement kit for the Carrier PG8JAA066135AAJA mid-efficiency gas furnace. The hot surface igniter (HSI) is the component that glows bright orange to ignite the gas burners on every heating cycle. When it fails, your furnace will attempt ignition, fail to light, and lock out — leaving you with no heat. Common symptoms include the inducer motor running normally but burners never lighting, or an error code indicating ignition failure after 3 attempts.

• Specs: OEM Part #331930-751 | 120V hot surface ignition | Silicon nitride element | Replaces legacy part LH33ZG001 | Rated for 33" tall mid-efficiency furnace cabinets
• What's Included: Silicon nitride igniter element, mounting bracket, OEM wiring connector, high-temperature wire nuts, and installation instructions — everything needed for a complete, code-compliant swap.
• OEM vs Generic: OEM silicon nitride igniters are factory-tolerance matched for the PG8JAA series. Generic aftermarket igniters often use inferior silicon carbide elements with higher fragility and shorter service life. The OEM kit includes the correct bracket geometry and connector, eliminating adapter guesswork.
• Install Difficulty: 2/5 — Shut off gas and power before beginning. Allow the old igniter to cool completely before handling. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Handle the igniter element by the ceramic base only — skin oils on the silicon nitride surface cause premature failure. Estimated time: 20–30 minutes.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
