OEM Carrier Silicon Nitride Hot Surface Igniter LH33ZG002 for Model PG9MTAV60125ABSS

This genuine OEM hot surface igniter (part number LH33ZG002) is the factory-specified replacement for the Carrier PG9MTAV60125ABSS gas furnace. The igniter is the critical component that glows to ignition temperature and lights the gas burners on each heating cycle. When it fails — either through a crack in the element or loss of continuity — the furnace control board detects no flame establishment and locks out after one or two ignition attempts, leaving you with a no-heat call. The silicon nitride construction on this OEM igniter offers superior durability over legacy silicon carbide designs, with greater resistance to thermal shock and a longer service life.

• Part Type: Hot Surface Igniter (HSI) | Silicon Nitride element | OEM part number LH33ZG002 | Cross-reference: 1172533
• OEM vs Generic: This is a genuine Carrier OEM igniter — not a universal aftermarket substitute. OEM igniters are matched to the exact wattage, geometry, and mounting bracket of the PG9MTAV60125ABSS, ensuring correct element temperature and reliable light-off every cycle. Generic universal kits may require bracket modification and often operate at mismatched wattages, leading to premature burnout or nuisance lockouts.
• Install Difficulty: 2/5 — Always disconnect power and allow the furnace to cool before servicing. Do not touch the nitride element with bare hands — skin oils accelerate cracking. Tools needed: 1/4" nut driver, flat-blade screwdriver, multimeter (to verify open circuit on failed igniter). Typical replacement time: 20–30 minutes.
• Warranty & Shipping: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff. Carefully packaged to prevent element damage in transit.
