OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA066110ADJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8MAA066110ADJA gas furnace. The hot surface igniter is a critical component in the furnace ignition sequence — it heats to temperatures exceeding 1,800°F to ignite the gas burner on each heating call. When the igniter fails, the furnace control board detects a failed ignition attempt and initiates a safety lockout, leaving you with no heat. Common failure symptoms include the furnace running through the full ignition cycle but producing no flame, a cracked or broken igniter element visible through the burner sight glass, or a fault code on the control board indicating ignition failure.

• Specs: Hot surface igniter | Silicon nitride element | Factory-matched geometry and resistance | 120V operation | Rated for Carrier PG8MAA series furnaces
• OEM vs Generic: This is a genuine OEM Carrier igniter engineered to exact factory resistance and geometry specifications. Aftermarket igniters frequently deviate in element resistance and mounting dimensions, causing nuisance lockouts, premature failure, or improper flame positioning that can trip the flame sensor.
• Install Difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Handle by the ceramic base or bracket only. Allow the furnace to cool completely before removal.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
