OEM Carrier Hot Surface Igniter Kit 120V for Model PG8UAA036045ACJA

This is the factory OEM hot surface igniter kit (part number 332505-751) for the Carrier PG8UAA036045ACJA gas furnace. The hot surface igniter is the critical first step in every heating cycle — it heats to approximately 1,800°F to ignite the gas burners the moment the gas valve opens. When this component fails, the furnace will attempt ignition, fail to light, and lock out after one to three tries, leaving you with no heat. Common symptoms include a furnace that runs the inducer and clicks through a call for heat but produces no flame, or a visibly cracked silicon nitride element.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes wire harness, mounting bracket, and hardware | OEM part number 332505-751 (cross-reference: LH33ZG001)
• OEM vs Generic: This factory-matched OEM kit ensures the correct voltage draw, element geometry, and bracket fitment. Generic igniters often run at slightly different wattages, causing premature burnout or unreliable ignition in cold ambient conditions.
• Install difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Unplug the harness connector, remove the single mounting screw, swap the igniter, and secure the bracket. Avoid touching the silicon nitride element with bare hands — skin oils accelerate thermal cracking.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse on all in-stock orders.
