OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA024070ACJA

This is the factory OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8JAA024070ACJA packaged gas unit. The igniter is the first component to activate on every call for heat — the control board energizes it to glow white-hot, igniting the gas burner within seconds. When the igniter fails, the furnace or packaged unit will attempt ignition, fail to light, and lock out — leaving you with no heat. Symptoms include the system cycling on but producing no warm air, accompanied by a fault code indicating an ignition failure.

• Specs: 120V hot surface igniter | Silicon nitride element | Includes bracket and wiring harness | OEM part number LH33ZG001 | Factory-matched fit for Carrier PG8JAA024070ACJA
• OEM vs Generic: This is a genuine Carrier OEM igniter — engineered to exact temperature and resistance specifications for your unit. Generic igniters frequently use inferior silicon carbide elements that are more brittle, crack under vibration, and fail prematurely. OEM is the safest choice for a furnace or packaged unit with high daily cycle counts.
• Install difficulty: 2/5 — De-energize and lock out the unit at the disconnect before beginning. Allow the igniter to cool completely if recently operated. Do NOT touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, needle-nose pliers. Disconnect the wiring harness, remove the mounting screw, swap the igniter, and reconnect. Always verify ignition on the first call for heat before closing the cabinet.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
