OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB048060AASA

This is the genuine OEM hot surface igniter for the Carrier PG9MAB048060AASA packaged gas unit. During every call for heat, the control board energizes this igniter to glow white-hot, igniting the gas burner within seconds. When the igniter fails — due to cracking, contamination, or end-of-life degradation — the unit will attempt ignition, fail to light the burner, and enter a safety lockout. The result: no heat and a blinking fault code on the control board. Replacing the igniter with the correct OEM part (LH33ZG001) is one of the most common and straightforward furnace repairs.

• Specs: OEM Part # LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Lightweight at ~0.07 lbs | Plug-and-play connector for direct OEM replacement
• OEM vs Generic: Genuine Carrier OEM igniters are manufactured to exact factory resistance and fragility tolerances. Off-brand igniters frequently deviate in element geometry and resistance, causing mistimed ignition or premature cracking — always choose OEM on gas-ignition components.
• Install Difficulty: 2/5 — De-energize and lock out the unit before starting. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element prematurely. Disconnect the harness, remove the single mounting screw, swap the igniter, and reconnect. Verify ignition on first call for heat.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
