OEM Carrier Hot Surface Igniter Kit 332505-751 for Model GB3AAV024070ADJA

This is the factory-specified OEM hot surface igniter replacement kit (part number 332505-751) for the Carrier GB3AAV024070ADJA gas furnace. The hot surface igniter is a critical component in the ignition sequence — it heats to temperatures exceeding 1800°F to ignite the gas burners on each heating cycle. When the igniter fails, the furnace control board will attempt ignition, detect no flame, and enter a safety lockout, leaving your home without heat. Common symptoms include the furnace cycling on but never producing heat, a blinking fault code indicating ignition failure, or a visibly cracked or broken igniter element.

• Specs: Silicon nitride hot surface igniter | 120V input | Factory-matched element geometry and lead wire harness | Includes mounting hardware as part of complete kit
• OEM vs Generic: This OEM Carrier igniter (332505-751) is manufactured to exact factory specifications for element temperature, warm-up timing, and electrical resistance. Generic igniters frequently use mismatched resistance ratings that cause premature burnout or misfire with the factory control board.
• Install Difficulty: 3/5 — Turn off gas and electrical supply before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify resistance before powering up. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Use gloves or the included packaging to handle the element.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
