OEM Carrier Hot Surface Igniter 120V for Model PG9MAA048060ABKA (LH33ZS004)

This is the genuine OEM hot surface igniter for the Carrier PG9MAA048060ABKA gas furnace. The igniter is the first component to activate on every call for heat — it glows to roughly 2,000°F, igniting the gas burner within seconds. When it fails, the furnace will attempt ignition one to three times and then lock out, leaving you with no heat. Common symptoms include the inducer and blower running normally but the burners never lighting, or an ignition fault error code on the control board.

• Specs: 120V AC | 5 Amp draw | OEM part number LH33ZS004 | Silicon carbide element | Factory-matched connector and mounting bracket
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory resistance and thermal tolerances. Generic igniters often carry wider resistance variance, leading to inconsistent light-off or premature cracking of the element — especially in cold-start conditions.
• Install difficulty: 2/5 — Power down the furnace and allow the igniter to cool completely before handling. Tools needed: 1/4" nut driver, needle-nose pliers. Caution: Never touch the silicon carbide element with bare hands — skin oils cause hot spots that crack the element. Photograph wiring harness before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
