OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB024060AASA

This is the genuine OEM hot surface igniter for the Carrier PG9MAB024060AASA packaged gas unit. The igniter is the first component activated in every heating cycle — the control board energizes it to bring the element to ignition temperature (typically 1,800–2,500°F), which then ignites the gas burner. When the igniter fails, the furnace will attempt to light, fail to prove flame, and go into a hard lockout — leaving you with no heat. Common symptoms include a no-heat call with no visible glow at the burner, repeated ignition attempts followed by lockout, or a visibly cracked or broken igniter element.

• Part Number: LH33ZG001 | OEM Carrier / Bryant replacement igniter | 120V AC input
• OEM vs Generic: This factory-original igniter is manufactured to exact Carrier specifications for element resistance, mounting geometry, and connector fit. Generic igniters can have off-spec resistance values, leading to premature failure or unreliable ignition — particularly in cold-start conditions.
• Install Difficulty: 2/5 — De-energize the unit at the disconnect before beginning. Avoid touching the igniter element with bare hands — skin oils cause hot spots and premature cracking. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the harness plug, remove the mounting screw(s), and reverse to install. Photograph wiring before disconnecting.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
