OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8MAA036070AAJA

This is the genuine OEM Carrier hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8MAA036070AAJA gas furnace. The hot surface igniter is the critical component that glows red-hot to ignite the gas burner on every heating cycle. When it fails, the furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. This kit upgrades to a durable silicon nitride igniter, replacing the older silicon carbide style (LH33ZS004) used in many 33" tall furnace models, and includes everything needed for a clean, professional installation.

• Specs: 120V AC hot surface igniter | Silicon nitride element | Operating voltage: 98–132 VAC | Time to ignition temperature: <17 seconds @ 120V | Cold resistance: 34–64 Ohms @ 75°F | OEM Part #331930-751
• Kit Includes: Silicon nitride igniter element, mounting bracket, OEM-matched connector, and high-temperature wire nuts — a complete drop-in upgrade solution with no additional hardware required.
• OEM vs Generic: This genuine Carrier OEM kit is factory-calibrated to the exact voltage and thermal rise curve of your PG8MAA036070AAJA furnace control board. Generic igniters may operate outside tolerance, causing nuisance lockouts or premature element failure.
• Install Difficulty: 2/5 — Turn off gas and electrical supply before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, multimeter (to verify cold resistance). Allow igniter to cool fully before handling. Typical install time: 20–30 minutes.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse on all in-stock orders.
