OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA036060AEKA

This is the OEM factory-specified hot surface igniter for the Carrier PG9MAA036060AEKA gas furnace. The igniter is the first active component in your furnace's heating sequence — it glows to over 2,000°F to ignite the gas burners on every call for heat. When it fails or cracks, the furnace will attempt ignition, fail to light the burners, and enter a lockout condition — leaving you with a blinking fault code and no heat. Replacing it with the correct OEM part (LH33ZS004) ensures a precise fit and reliable ignition cycle every time.

• Specs: OEM Part No. LH33ZS004 | Silicon nitride element | 120V operation | Factory-matched geometry and lead length for drop-in replacement
• OEM vs Generic: OEM silicon nitride igniters are manufactured to exact resistance and thermal-shock tolerances specified by Carrier engineering. Generic alternatives often vary in element thickness and mounting geometry, leading to misalignment in the burner assembly or premature cracking under thermal cycling.
• Install Difficulty: 2/5 — Turn off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Never touch the ceramic element with bare hands — skin oils cause hot spots that crack the element prematurely. Use nitrile gloves or handle only by the wiring harness and bracket.
• Warranty: 1-year OEM factory warranty. Ships same business day from our climate-controlled warehouse — packaged with foam inserts to protect the fragile ceramic element in transit.

Compatibility: Engineered as a direct OEM replacement for the Carrier PG9MAA036060AEKA gas furnace.
