OEM Carrier Hot Surface Igniter Replacement Kit 332505-751 for Model GB3AAV024070ACJA

This OEM hot surface igniter kit (part number 332505-751) is the factory-specified replacement for the Carrier GB3AAV024070ACJA gas furnace. The hot surface igniter is a critical component in your furnace's ignition sequence — it heats to over 1,800°F within seconds to ignite the gas burners on each heating call. When the igniter fails or cracks, the furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common symptoms include the furnace cycling on but shutting down after 30–90 seconds, error codes indicating ignition failure, or a visibly cracked igniter element.

• Specs: Silicon nitride hot surface igniter | Factory-matched electrical resistance | Includes mounting hardware and wire harness connector | Rated for natural gas and propane applications
• OEM vs Generic: This OEM kit from Carrier meets exact factory resistance and thermal cycling specifications. Generic igniters frequently use silicon carbide elements with inconsistent resistance tolerances, leading to premature cracking and repeat failures — especially in variable-temperature attic or basement installations.
• Install Difficulty: 2/5 — Always disconnect power and shut off gas before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots and early failure. Use gloves or handle by the ceramic base only.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our stocked warehouse.

Compatibility: Designed specifically for the Carrier GB3AAV024070ACJA gas furnace. Always verify your existing igniter's connector style and mounting configuration against this kit before installation. If you have questions about fitment, our HVAC parts specialists confirm compatibility before you order — no guesswork required.
