OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA048110ACJA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG8JAA048110ACJA packaged gas unit. The hot surface igniter is a critical component in the heating ignition sequence — on every call for heat, the control board energizes the igniter to glow at temperatures exceeding 1,800°F, igniting the gas burner within seconds. When the igniter fails, the furnace or packaged unit will attempt ignition, come up short, and lock out — leaving you with a system that runs the inducer but delivers no heat. A cracked or contaminated igniter element is one of the most common causes of no-heat service calls.

• Specs: 120V hot surface igniter | Includes mounting bracket and wiring harness | Silicon element rated for high-cycle durability | Factory-matched to Carrier ignition sequence timing
• OEM vs Generic: This is a genuine Carrier OEM igniter. Generic aftermarket igniters are often made with silicon carbide elements that are more brittle and crack-prone. OEM silicon nitride elements offer superior thermal shock resistance and longer service life, protecting the control board from repeated failed ignition retries.
• Install difficulty: 2/5 — Always de-energize equipment at the disconnect before beginning. Avoid touching the igniter element with bare hands — skin oils cause hot spots that shorten element life dramatically. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify continuity on the failed part. Reconnect the wiring harness plug and verify ignition sequence before closing the panel.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
