OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA060080ADKA

This is the OEM factory-specified hot surface igniter for the Carrier PG9MAA060080ADKA gas furnace. During each heating cycle, the igniter heats to approximately 2,000°F to ignite the gas burner. When it fails — due to age, vibration, or thermal cycling — the furnace will attempt ignition, fail to light the burner, and go into a lockout fault. Typical symptoms include the furnace running through an ignition sequence and then shutting down with a flashing error code indicating a failed ignition attempt, leaving you with no heat.

• Specs: 120V AC | 5 Amp draw | Silicon carbide hot surface igniter | OEM part number LH33ZS004 | Factory-specified tolerance for reliable ignition
• OEM vs Generic: OEM igniters are manufactured to exact resistance and thermal mass specifications. Generic or off-brand igniters frequently carry wider tolerances, leading to slower heat-up times, unreliable ignition, and premature cracking — the most common cause of early igniter failure.
• Install difficulty: 2/5 — Turn off gas and power before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Critical: Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Use gloves or handle by the ceramic bracket only.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
