OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA060100ABKA

This is the genuine OEM hot surface igniter (part number LH33ZS004) factory-specified for the Carrier PG9MAA060100ABKA gas furnace. The hot surface igniter is the first active component to fire during every heating cycle — it heats to over 1,800°F within seconds to ignite the gas burner. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out the system, leaving you with no heat. Common failure symptoms include a hard lockout fault code, the furnace cycling on and off without firing, or a visibly cracked or broken silicon carbide element.

• Specs: 120V AC input | 5 Amp draw | Silicon carbide element | OEM part number LH33ZS004 | Factory-matched fit, form, and function for Carrier PG9MAA060100ABKA
• OEM vs Generic: OEM igniters are manufactured to exact Carrier tolerances for resistance, warm-up time, and mechanical fit. Generic aftermarket igniters can exhibit inconsistent resistance values, premature cracking, or mismatched mounting geometry — leading to repeated lockouts or a shortened service life.
• Install difficulty: 2/5 — Power down and lock out the furnace before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. The igniter is fragile — never touch the element with bare hands, as skin oils cause hot spots and premature failure. Verify ignition sequence operation after replacement.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
