OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA024070AGJA

This is the factory-specified OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8MAA024070AGJA packaged gas unit. The igniter is the first component to activate on every heating call — it glows to ignition temperature within seconds, lighting the gas burner as the valve opens. When it fails, the control board will attempt ignition, find no flame, and lock out the system, leaving you with no heat. Common symptoms include a furnace that attempts to start and then goes into lockout after 30–90 seconds, or a visibly cracked or broken igniter element.

• Specs: OEM Part # LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Factory-matched geometry and resistance for Carrier packaged gas units
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory tolerances. Generic or aftermarket igniters often vary in element resistance and mounting geometry, leading to premature failure or nuisance lockouts. Always choose OEM for a critical ignition component.
• Install difficulty: 2/5 — De-energize and lock out the unit before beginning. Avoid touching the ceramic or silicon nitride element — skin oils cause hot spots and early failure. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, multimeter (to verify element resistance). Disconnect the harness plug, remove the single mounting screw, swap and reconnect. Verify ignition on the next heating call.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
