OEM Carrier Hot Surface Igniter LH33ZS004 for Model PG9MAA036080ADKA

This is the factory OEM hot surface igniter for the Carrier PG9MAA036080ADKA gas furnace. Rated at 120V / 5 Amps, the igniter is the silicon carbide element that glows red-hot during every heating cycle to ignite the gas burner. When it fails, the furnace control board will attempt ignition, detect no flame, and lock out — leaving you with a no-heat call, a blinking fault code, or a system that short-cycles and then shuts down. Replacing the igniter with the correct OEM part restores reliable ignition and prevents nuisance lockouts.

• Specs: OEM Part # LH33ZS004 | 120V AC | 5 Amp draw | Silicon carbide element | Factory-matched fit and lead length for Carrier PG9MAA036080ADKA
• OEM vs Generic: OEM Carrier igniters are manufactured to exact factory resistance and watt density specifications. Generic alternatives vary widely in element composition and wiring harness length, leading to premature cracking, inconsistent glow temperatures, and repeat failures.
• Install Difficulty: 2/5 — Always disconnect power before servicing. Allow the old igniter to cool completely before removal — silicon carbide is extremely fragile when hot. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the new igniter element with bare hands; skin oils cause hot spots that crack the element. Estimated repair time: 15–20 minutes.
• Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our warehouse.
