OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA036045ADJA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG8JAA036045ADJA packaged gas unit. The hot surface igniter is the first active component in the ignition sequence — on every call for heat, the control board energizes the igniter to temperatures exceeding 1,800°F, which then ignites the gas burner. When the igniter fails, the furnace will attempt one or more ignition trials, then lock out on a fault code. Common symptoms include a no-heat call, a furnace that clicks or attempts to start but produces no flame, or a system that locks out after 30–90 seconds with no ignition.

• Part Number & Specs: OEM Part # LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Factory-matched geometry and connector plug for direct drop-in fit
• OEM vs Generic: OEM igniters are manufactured to exact temperature rise curves and element thickness specifications. Aftermarket igniters often use silicon carbide elements with inconsistent resistance tolerances, leading to premature cracking and repeat failures — especially on Carrier packaged units with tighter ignition timing windows.
• Install Difficulty: 2/5 — Shut off power and gas before beginning. Never touch the igniter element with bare hands — skin oils cause hot spots and premature cracking. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Disconnect the wiring harness, remove the single mounting screw, swap the igniter, and reconnect the plug. Verify ignition on the first call for heat.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse. Lightweight part (approx. 0.10 lbs) — qualifies for fast small-package delivery nationwide.
