OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB060140AASA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG9MAB060140AASA packaged gas unit. The igniter is the first critical component in every heating cycle — the control board energizes it to reach operating temperature, then opens the gas valve to ignite the burners. When the igniter fails, the furnace will attempt ignition, fail to light, and enter a safety lockout, leaving you with no heat. Common failure symptoms include a system that starts its heating sequence but shuts off within 30–90 seconds, a cracked or broken igniter element visible on inspection, or repeated "soft lockout" fault codes on the control board.

• Specs: 120V AC | Silicon nitride element | Includes bracket and wiring harness | Direct OEM factory replacement for part number LH33ZG001
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory resistance and temperature specifications. Generic igniters often vary in element geometry and resistance tolerance, leading to unreliable ignition or premature cracking — especially in packaged rooftop applications subject to vibration and wide temperature swings.
• Install difficulty: 2/5 — Always de-energize and lock out the unit before servicing. Avoid touching the igniter element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Disconnect harness, remove mounting screws, swap element, reconnect, and verify ignition sequence through one full heating cycle.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
