OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA048110AEJA

This is the genuine OEM Carrier hot surface igniter (part number LH33ZG001), factory-specified for the Carrier PG8MAA048110AEJA packaged gas unit. The hot surface igniter is the first component to activate on every call for heat — the control board energizes it to glow at over 1,800°F, igniting the gas burner within seconds. When the igniter fails, the furnace or packaged unit will attempt ignition, fail to light, and enter a hard lockout — leaving you with no heat and a blinking fault code. Cracked, contaminated, or open-circuit igniters are among the most common causes of no-heat service calls.

• OEM Part Number: LH33ZG001 | Manufacturer: Carrier | Includes bracket and wiring harness | 120V rated
• OEM vs Generic: This is the genuine Carrier factory part — engineered to exact resistance and thermal-shock tolerances for your PG8MAA048110AEJA. Aftermarket igniters may use inferior silicon carbide elements prone to premature cracking, shortening service life significantly.
• Install Difficulty: 2/5 — De-energize and lock out the unit before beginning. Avoid touching the igniter element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, flat-blade screwdriver, and a multimeter to verify element continuity (typical resistance: 40–90 ohms). Consult your service manual for igniter placement and harness routing.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
