OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA036110AFJA

This is the genuine OEM hot surface igniter (part# LH33ZG001) factory-specified for the Carrier PG8JAA036110AFJA packaged gas unit. The hot surface igniter is the first critical component to fire during every heating cycle — the control board energizes it to reach ignition temperature, opening the gas valve only after the element glows hot enough to reliably light the burner. When the igniter fails, the system will attempt ignition, fail to establish flame, and lock out — leaving you with a blinking fault code and no heat. Common symptoms include repeated ignition attempts with no burner flame, a hard lockout after 3 tries, or a visibly cracked element on inspection.

• Specs: 120V AC | Silicon nitride element | Includes bracket and wiring harness | Factory-matched to Carrier PG8JAA036110AFJA ignition sequence
• OEM vs Generic: OEM igniters are manufactured to exact factory resistance and warm-up timing tolerances. Generic igniters can vary significantly in warm-up time and surface temperature, leading to nuisance lockouts or premature cracking under thermal cycling.
• Install Difficulty: 2/5 — De-energize and disconnect power before starting. Do not touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, needle-nose pliers, phone camera to document wiring. Replacement typically takes 20–30 minutes.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
