OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG9MAB060120ACSA

This is the genuine OEM hot surface igniter for the Carrier PG9MAB060120ACSA packaged gas unit. The igniter is the first active component in the ignition sequence — on a call for heat, the control board energizes it to reach temperatures exceeding 1,800°F before opening the gas valve. When the igniter fails, the furnace attempts ignition, fails to light the burner, and enters a safety lockout — typically after 1–3 attempts. Common symptoms include no heat, a flashing fault code on the control board, or a furnace that ignites intermittently and then locks out.

• Part Number & Specs: OEM Part # LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Includes mounting bracket and wiring harness | Factory-matched to Carrier ignition timing sequence
• OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory resistance and heat-up time tolerances. Aftermarket igniters often vary in warm-up timing, which can cause nuisance lockouts or premature element cracking — especially in colder ambient conditions.
• Install Difficulty: 2/5 — Always shut off gas supply and disconnect power before beginning. Tools needed: 1/4" hex driver, needle-nose pliers, multimeter (to verify open element before replacement). Do not touch the ceramic element with bare hands — skin oils cause hot spots that crack the element prematurely. Use gloves or handle by the bracket only.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day when ordered before cutoff. Carefully packaged to prevent element breakage in transit.
