OEM Carrier Hot Surface Igniter for Model PG8JAA060155ADJA (LH33ZG001)

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8JAA060155ADJA gas furnace. The igniter is a critical component in the furnace ignition sequence — it heats to approximately 2,000°F to ignite the gas burners on every heating cycle. When it fails, the furnace will attempt ignition, fail to light, and enter a safety lockout, leaving you with no heat. A cracked, broken, or open-circuit igniter is one of the most common causes of furnace no-heat calls.

• Specs: Hot surface igniter | Silicon nitride element | Factory OEM replacement for Carrier LH33ZG001 | Operates on 120V furnace ignition circuit | Designed for exact fit and factory-matched resistance
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact material and resistance specifications. Generic igniters often use lower-grade silicon carbide elements that are more brittle and prone to premature cracking — especially in high-cycle applications. OEM ensures correct warm-up time and reliable arc-free lighting.
• Install Difficulty: 3/5 — Power down and lock out the furnace before beginning. Allow the igniter to cool completely if the unit has run recently. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify open circuit on failed igniter). Never touch the igniter element with bare hands — oils from skin cause hot spots and premature failure. Use gloves or handle by the ceramic base only.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
