OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG9MAB060140LBSA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG9MAB060140LBSA packaged gas unit. The igniter is the critical first step in every heating cycle — the control board energizes it to reach ignition temperature, which then lights the gas burner. When this component fails, the furnace will attempt to ignite, fail to sense a flame, and lock out after one to three tries, leaving you with no heat. Common symptoms include a hard lockout fault code, the inducer running but no burner ignition, or visible cracking on the igniter element.

• Specs: 120V hot surface igniter | Silicon nitride element | Factory OEM part number LH33ZG001 | Plug-and-play harness connector | Weight: 0.10 lbs
• OEM vs Generic: OEM silicon nitride igniters are manufactured to exact resistance and warm-up time tolerances required by the Carrier control board. Generic igniters can exhibit incorrect resistance values, causing nuisance lockouts or premature burnout — OEM is always the recommended choice for reliable ignition sequencing.
• Install difficulty: 2/5 — De-energize the unit and allow the igniter to fully cool before handling. Never touch the ceramic element with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect harness, remove mounting screw, swap igniter, reconnect. Verify ignition on first call for heat.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
