OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA048070ACJA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG8JAA048070ACJA packaged gas unit. During every call for heat, the control board energizes the igniter, which heats to over 1,800°F to light the burner. When it fails — typically due to hairline cracks in the element or contamination from skin oils — the furnace will attempt ignition, fail to light, and go into a safety lockout. The most common symptom is a complete no-heat condition with a fault code indicating failed ignition after one or more attempts.

• Specs: OEM Part # LH33ZG001 | Hot surface igniter type | Includes mounting bracket and wiring harness | Factory-matched element resistance and geometry for reliable light-off
• OEM vs Generic: This is a genuine Carrier OEM igniter — not a universal substitute. Generic silicon carbide igniters often differ in element geometry, resistance rating, and connector type, leading to misfire or premature failure. OEM ensures correct warm-up timing and a precise fit with zero modifications.
• Install difficulty: 2/5 — Power down and lock out the unit before servicing. Never touch the igniter 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 sequence on first call.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse in original OEM packaging.
