OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA060140AEKA

This is the genuine OEM Carrier hot surface igniter (part number LH33ZS004), factory-specified for the Carrier PG9MAA060140AEKA gas furnace. The hot surface igniter is the first component activated in every heating cycle — it glows red-hot at approximately 2,500°F to ignite the gas burner. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out — leaving you with no heat and a fault code on the board. Common symptoms include the inducer running normally but the burner never lighting, or repeated ignition lockout codes (typically 3-flash or 4-flash error sequences).

• Specs: 120V AC input | 5 Amp draw | Silicon carbide element | Factory-matched geometry and harness connector for direct drop-in fit on the PG9MAA060140AEKA
• OEM vs Generic: OEM Carrier igniters are manufactured to exact resistance and thermal-shock tolerances. Generic silicon carbide igniters frequently run outside spec, causing nuisance lockouts or premature cracking — OEM is the only choice for reliable, long-term ignition performance.
• Install difficulty: 2/5 — Turn off power and gas before starting. Tools needed: 1/4" nut driver, needle-nose pliers. Handle the igniter element only by its bracket — never touch the silicon carbide tip with bare hands, as skin oils cause hot-spot cracking. Photograph wiring before disconnecting.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
