OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB036080LBSA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG9MAB036080LBSA 80% AFUE gas furnace. The igniter is a critical component in the ignition sequence — it heats to over 1,800°F within seconds to light the burner assembly. When it fails, the control board will attempt ignition, detect no flame, and lock out the furnace, leaving you with a no-heat call. Common symptoms include a furnace that cycles on, attempts ignition 2–3 times, and then displays a fault code without ever firing the burners.

• Specs: Hot surface igniter | Silicon nitride element | 120V input | Factory OEM part number LH33ZG001 | Direct plug-in connector — no splicing required
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory temperature rise and resistance specifications. Generic igniters often use silicon carbide elements that are more brittle, more prone to cracking from vibration or grease contamination, and carry a wider resistance tolerance that can cause nuisance lockouts.
• Install difficulty: 2/5 — Turn off power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Do not touch the igniter element with bare hands — skin oils cause premature failure. Photograph wiring connections before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
