OEM Carrier Hot Surface Igniter (Silicon Nitride) LH33ZG001 for Model PG8JAA036110ADJA

This is the factory OEM hot surface igniter for the Carrier PG8JAA036110ADJA packaged gas furnace. The igniter is the heart of your furnace's ignition sequence — on every call for heat, the control board energizes the igniter to glow at extreme temperature, igniting the gas burner within seconds. When it fails, the furnace will attempt ignition, fail to light, and go into safety lockout, leaving you with no heat. Common symptoms include a furnace that cycles but never fires, a fault code indicating ignition failure, or a visibly cracked or broken igniter element.

• Part Number & Type: OEM Part # LH33ZG001 | Silicon Nitride hot surface igniter | 120V | Factory-authorized Carrier replacement
• OEM vs Generic: This OEM silicon nitride igniter is engineered to the exact resistance and thermal cycling specifications of your Carrier unit. Generic igniters often use silicon carbide elements with wider tolerance bands, leading to premature cracking and repeat failures — especially in high-cycle applications.
• Install Difficulty: 2/5 — Always de-energize the unit and allow the igniter to cool completely before handling. Never touch the ceramic igniter element with bare hands — skin oils cause hot spots and premature cracking. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the plug harness, remove the single mounting screw, swap, and reconnect. Verify ignition on next heat call.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse. Includes mounting hardware bracket as specified for this model.

Compatibility: Engineered as the direct OEM drop-in replacement for Carrier model PG8JAA036110ADJA.
