OEM Carrier Hot Surface Igniter Replacement Kit 331930-751 for Model PG8MAA048110ABJA

This is the genuine OEM Carrier hot surface igniter replacement kit (part #331930-751) factory-specified for the Carrier PG8MAA048110ABJA gas furnace. The hot surface igniter is the component that glows red-hot to ignite the gas burners on each heating cycle. When it fails, your furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. This kit upgrades your system to the more durable silicon nitride (Si₃N₄) element, replacing the older silicon carbide igniter (LH33ZS004) found in many 33" tall Carrier furnace models.

  • Specs: 120 VAC | Silicon Nitride flat igniter | Steady-state current: 0.8–2.0 A | Cold resistance: 34–64 Ohms @ 75°F | Time to 1800°F: <17 seconds | Max temp: 2732°F (1500°C) @ 132 VAC | Kit includes OEM mounting bracket, OEM connector, and high-temperature wire nuts
  • OEM vs Generic: This factory-genuine kit is engineered to exact Carrier tolerances. Generic igniters often use lower-grade ceramic blends with wider resistance variance, increasing the risk of premature cracking and nuisance lockouts. The OEM silicon nitride element is significantly more crack-resistant than the original silicon carbide design it replaces.
  • Install Difficulty: 2/5 — This is a straightforward swap suitable for experienced DIYers and technicians alike. Tools needed: ¼" nut driver, needle-nose pliers, voltage tester. Always shut off gas supply and disconnect power before servicing. Allow the old igniter to cool completely before handling — silicon nitride is brittle and must not be touched with bare hands (skin oils cause hot spots and cracking). Use the included bracket and harness for a clean, plug-and-play installation.
  • Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PG8MAA048110ABJA gas furnace. Also replaces OEM part number LH33ZS004 in compatible 33" tall Carrier, Bryant, and Payne furnace models. Always verify your model's data plate and existing igniter part number before ordering. Our HVAC parts specialists are available to confirm fitment — contact us before you order.

Is this igniter compatible with Bryant or Payne too?
