OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG8MAA036045ADJA

This is the genuine OEM hot surface igniter for the Carrier PG8MAA036045ADJA packaged gas unit. The igniter is the first active component in your furnace's ignition sequence — the control board energizes it to approximately 2,000°F, then opens the gas valve to ignite the burner. When it fails, the board will attempt ignition one to three times and enter a hard lockout, leaving you with no heat. Classic symptoms include a blinking fault code for "ignition failure" or the burner lighting briefly and then failing on subsequent cycles.

• OEM Part Number: LH33ZG001 | 120V hot surface igniter | Factory-original Carrier replacement with bracket and harness connector pre-attached
• OEM vs Generic: This factory OEM igniter is manufactured to exact Carrier resistance and temperature specifications. Generic igniters often deviate in resistance tolerance, causing nuisance lockouts or premature failure — especially problematic on packaged rooftop units exposed to outdoor temperature swings.
• Install Difficulty: 3/5 — De-energize and lock out the unit before beginning. Do not touch the ceramic igniter element with bare hands — skin oils cause hot spots and cracking. Tools needed: 1/4" hex driver, needle-nose pliers, multimeter (verify 40–90Ω resistance before install). Reconnect harness connector and confirm ignition sequence through one full heating cycle.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
