OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA036070AEJA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG8MAA036070AEJA packaged gas unit. The hot surface igniter is the critical first step in every heating cycle — the control board energizes the igniter, it heats to approximately 1800°F, and that glow lights the gas burner. When the igniter fails, the furnace will attempt ignition, fail to prove flame, and lock out — leaving you with no heat. Common symptoms include a system that clicks on but produces no heat, a burner that won't light, or repeated ignition lockout fault codes.

• OEM Part Number: LH33ZG001 | 120V hot surface igniter | Silicon nitride element | Factory-matched fit for Carrier PG8MAA036070AEJA
• OEM vs Generic: This genuine Carrier OEM igniter is manufactured to exact factory resistance and thermal specifications. Generic igniters can vary in warm-up time and element geometry, leading to nuisance lockouts or premature failure — especially in packaged rooftop applications with vibration exposure.
• Install Difficulty: 2/5 — De-energize and lock out the unit before beginning. Never touch the igniter element with bare hands — skin oils cause hot spots and premature cracking. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify element continuity (typically 40–90Ω). Swap the two-wire plug connector and secure the mounting bracket.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
