OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB036040ABSA

This is the OEM factory-specified hot surface igniter (part number LH33ZG001) for the Carrier PG9MAB036040ABSA packaged gas unit. The igniter is the first critical component in the ignition sequence — on every call for heat, the control board energizes it to glow white-hot, igniting the gas burner. When it fails, the furnace will attempt ignition one to three times and then go into hard lockout, leaving you with no heat. Common symptoms include a furnace that starts the ignition cycle but never lights, a cracked or broken igniter element, or error codes indicating an ignition failure on the control board.

• Specs: 120V AC input | Silicon nitride element | Includes mounting bracket and wiring harness | Factory-matched OEM replacement for Carrier part LH33ZG001
• OEM vs Generic: This OEM part is manufactured to exact Carrier factory tolerances for element resistance, warm-up time, and thermal cycling durability. Generic igniters may use silicon carbide elements with inconsistent resistance, leading to premature cracking and repeat failures.
• Install Difficulty: 2/5 — De-energize and lock out the unit before beginning. Do not touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, Torx T15 or T20 (varies by bracket), and needle-nose pliers. Photograph the harness routing before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3:00 PM local time ship same business day from our warehouse.
