OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB048060ACSA

This is the genuine OEM hot surface igniter (part number LH33ZG001), the factory-specified replacement for the Carrier PG9MAB048060ACSA packaged gas unit. The igniter is the first component to activate on every call for heat — the control board energizes it to reach ignition temperature, which then lights the gas burner. When it fails, the unit will attempt ignition, fail to sense a flame, and lock out — leaving you with no heat and a fault code. Visible cracks in the element, a glowing element that fails to ignite gas, or a furnace that locks out after 2–3 attempts are all telltale signs of a failed igniter.

• Specs: 120V AC input | Silicon nitride element (preferred over silicon carbide for durability) | OEM direct plug-in connector | Rated for continuous duty ignition cycling
• OEM vs Generic: The OEM Carrier LH33ZG001 is manufactured to exact factory tolerances for warm-up time and surface temperature. Generic igniters may reach ignition temperature too slowly or too quickly, causing nuisance lockouts or premature element failure — always the wrong choice for a packaged rooftop or gas unit under warranty.
• Install Difficulty: 2/5 — Shut off gas and disconnect power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Use gloves or handle only by the bracket and connector.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
