OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG92SAS30040AAAA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG92SAS30040AAAA 92% AFUE single-stage gas furnace. The hot surface igniter is the critical component that glows to ignition temperature — typically 1,800–2,500°F — to light the burner on every call for heat. When it fails, the control board will attempt ignition, detect no flame, and lock out the furnace, leaving you with no heat and a fault code on the board. Symptoms include a furnace that tries to start but shuts down after 30–90 seconds, repeated ignition lockouts, or a visibly cracked/broken igniter element.

• Specs: OEM silicon nitride hot surface igniter | Factory-rated voltage and wattage | Direct plug-in connector | Exact ceramic bracket and element geometry matched to Carrier PG92SAS30040AAAA burner assembly
• OEM vs Generic: This OEM igniter meets Carrier's precise resistance and warm-up timing tolerances. Generic igniters can have mismatched resistance specs, causing intermittent ignition failures or premature cracking under thermal cycling stress.
• Install Difficulty: 3/5 — Always disconnect power and shut off gas before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, work gloves. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Verify resistance with a multimeter before and after install (typical: 40–75 ohms).
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
