OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA036060ADKA

This is the genuine OEM Carrier hot surface igniter (part number LH33ZS004), factory-specified for the Carrier PG9MAA036060ADKA gas furnace. The hot surface igniter is the critical component that heats to approximately 2,000°F to ignite the gas burner on every heating cycle. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out — leaving you with no heat. Common symptoms include the furnace cycling on but failing to produce heat, a blinking fault code indicating ignition failure, or a visibly cracked or broken igniter element.

• Specs: 120V AC input | 5 Amp draw | Silicon carbide element | OEM part number LH33ZS004 | Direct factory replacement for Carrier PG9MAA036060ADKA
• OEM vs Generic: This is the genuine Carrier OEM part — not an aftermarket approximation. Generic igniters vary in resistance, element geometry, and heat-up time, which can result in inconsistent ignition, nuisance lockouts, and shortened service life. OEM ensures the exact factory fit and performance spec.
• Install difficulty: 2/5 — Turn off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Handle the igniter element only by its bracket — never touch the ceramic or silicon carbide element with bare hands, as skin oils will cause premature failure. Verify ignition sequence after installation.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
