OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB060120ABSA

This is the genuine OEM Carrier hot surface igniter (part number LH33ZG001), the factory-specified replacement for the Carrier PG9MAB060120ABSA packaged gas unit. The hot surface igniter is the critical first step in every heat cycle — the control board energizes the igniter, it glows to over 1,800°F, and that heat opens the gas valve and lights the burner. When the igniter cracks, weakens, or fails entirely, the furnace will attempt ignition, fail to prove a flame, and lock out — leaving you with no heat. Common symptoms include a furnace that tries to start but shuts off without heating, an error code indicating ignition lockout, or a visibly cracked or broken igniter element.

• OEM Part Number: LH33ZG001 | Genuine Carrier replacement | 120V rated | Silicon nitride element for extended service life and improved durability over older silicon carbide designs
• OEM vs Generic: This factory OEM igniter is manufactured to exact Carrier tolerances for resistance, warm-up time, and element geometry. Off-brand igniters frequently differ in resistance profile, causing nuisance lockouts or premature failure — especially in variable-speed and modulating systems.
• 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" and 5/16" nut drivers, needle-nose pliers. Disconnect the harness plug, remove the single mounting screw, swap the igniter, and verify ignition on the next heat call.
• Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse when ordered before cutoff.
