OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JEA048090AAJA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG8JEA048090AAJA packaged gas unit. The hot surface igniter is a critical component in the ignition sequence — when the thermostat calls for heat, the control board energizes the igniter to reach ignition temperature, then opens the gas valve to light the burners. When the igniter fails, the unit will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common symptoms include the unit cycling on and off repeatedly, an error code indicating ignition failure, or a visible crack or break in the igniter element.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes mounting bracket and wiring harness | OEM part number LH33ZG001 | Direct factory replacement
• OEM vs Generic: This genuine Carrier OEM igniter is manufactured to exact factory tolerances for element resistance, warm-up time, and mechanical fit. Aftermarket igniters frequently vary in resistance and warm-up profile, causing nuisance lockouts or premature element failure — especially in cold-start conditions.
• Install Difficulty: 2/5 — Shut off power and gas before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the silicon nitride element with bare hands — skin oils cause hot spots and premature cracking. Photograph wiring harness routing before disconnecting. Verify ignition sequence completes on first call for heat after install.
• Warranty: 1-year OEM factory warranty. In-stock — ships same business day from our warehouse when ordered before cutoff.
