OEM Carrier Hot Surface Igniter 120V for Model PG9MAA060140ACKA (LH33ZS004)

This is the OEM factory-specified hot surface igniter for the Carrier PG9MAA060140ACKA gas furnace. The igniter is the first critical component energized during every heating cycle — it heats to over 1,800°F to reliably light the gas burner. When it fails, the furnace will attempt ignition, fail to establish flame, and lock out after 1–3 attempts, leaving you with no heat. Common symptoms include a furnace that runs the inducer and hums but never ignites, or repeated hard lockout error codes on the control board.

• Specs: 120V AC | 5 Amp draw | Silicon carbide element | Factory OEM part number LH33ZS004 | Plug-and-play OEM connector
• OEM vs Generic: OEM silicon carbide igniters from Carrier are manufactured to exact resistance and thermal tolerances. Aftermarket igniters frequently exhibit inconsistent resistance values, leading to weak or failed ignition — especially in cold-start conditions.
• Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Never touch the ceramic element with bare hands — skin oils cause hot spots that crack the igniter prematurely. Disconnect the plug, remove the mounting screw, and swap directly.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
