OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JVB048090AAJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8JVB048090AAJA packaged gas unit. The igniter is the first component in the furnace ignition sequence — the control board energizes it to glow at temperatures exceeding 1,800°F, igniting the gas burner on a call for heat. When it fails, the furnace will attempt ignition, fail to sense a flame, and enter a hard lockout — leaving you with a blinking error code and no heat.

• Specs: 120V hot surface igniter | Silicon element construction | Includes mounting bracket and wiring harness | Factory-matched OEM fit for Carrier PG8JVB048090AAJA
• OEM vs Generic: OEM igniters are manufactured to exact factory resistance and element geometry specifications. Generic igniters often deviate in resistance tolerance, causing premature cracking or nuisance lockouts — especially in packaged units with high-vibration environments.
• Install difficulty: 2/5 — De-energize the unit and allow the element to fully cool before handling. Never touch the silicon element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect harness, remove mounting screw, swap igniter, reconnect. Test through one full heat cycle.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier PG8JVB048090AAJA packaged gas unit. Always verify your unit's part number on the data plate or existing igniter before ordering — element geometry and harness connector must match. Our fitment team is available to confirm compatibility before you purchase.
