OEM Carrier Hot Surface Igniter (Silicon Nitride) LH33ZG001 for Model PG8MVA036070AAJA

This OEM hot surface igniter is the factory-specified replacement for the Carrier PG8MVA036070AAJA packaged gas unit. During a call for heat, the control board energizes the igniter, which heats to over 2,000°F to ignite the gas burner. When the igniter fails — due to hairline cracks, contamination from skin oils, or age-related degradation — the furnace will attempt ignition, fail to detect a flame, and enter a safety lockout. You'll experience no heat with repeated short-cycling or a solid fault code on the control board.

• Specs: Silicon nitride element (Kyocera-manufactured) | 120V AC operating voltage | Includes mounting bracket and wiring harness | OEM part number: LH33ZG001
• OEM vs Generic: This is a genuine Carrier OEM igniter built to exact factory tolerances for heat-up time and element resistance. Aftermarket silicon nitride igniters vary in element geometry and can produce inconsistent ignition timing, leading to nuisance lockouts or premature failure.
• Install difficulty: 2/5 — Power down and lock out the unit before beginning. Never touch the silicon nitride element with bare hands — skin oils cause hot spots that crack the element. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver. Disconnect the old harness plug, remove the mounting screw, swap the igniter, and verify ignition on the next heat call.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.
