OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8MAA036110AAJA

This is the genuine OEM Carrier hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8MAA036110AAJA gas furnace. The hot surface igniter is the first component activated in every heating cycle — it glows to ignition temperature within seconds to light the burner. When it fails, the furnace control board will attempt ignition, find no flame, and lock out the system — leaving you with a cold house and a blinking fault code. This kit upgrades to a durable silicon nitride element, which is far more resistant to vibration and thermal shock than older silicon carbide igniters.

• Specs: 120 VAC | Silicon nitride flat-element design | Cold resistance: 34–64 Ohms @ 75°F | Steady-state current: 0.8–2A @ 120 VAC | Replaces OEM part LH33ZS004 in 33" tall furnace platforms
• Kit Includes: Silicon nitride igniter element, OEM-compatible mounting bracket, wire harness, and high-temperature wire connectors — everything needed for a clean, code-compliant swap with no splicing required
• OEM vs Generic: This is a genuine Carrier OEM kit, built to exact factory tolerances for the PG8MAA036110AAJA. Generic igniters often vary in element geometry and resistance spec, which can cause nuisance lockouts or premature failure. OEM means right the first time.
• Install Difficulty: 2/5 — Moderate DIY task. Turn off gas and power before starting. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify element resistance before install. Swap time is typically under 30 minutes for an experienced technician.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA036110AAJA gas furnace. This kit also fits a broad range of Carrier, Bryant, and Payne furnaces using the 33" tall chassis and LH33ZS004-series igniters — always confirm your model number and existing part number before ordering. Our fitment specialists are available to verify compatibility before you buy.
