This is the factory-specified OEM hot surface igniter replacement kit (part number 332505-751) for the Carrier GB3AAV036050AEJA gas furnace. The hot surface igniter is the critical component that glows to ignition temperature — typically 1,800–2,500°F — to light the burners each heating cycle. When it cracks, burns out, or fails to reach proper temperature, the control board will lock out the furnace after one or more failed ignition attempts, leaving you with no heat. Common symptoms include a furnace that attempts to start, clicks through the ignition sequence, then shuts down and flashes a fault code.
Compatibility: Designed specifically for the Carrier GB3AAV036050AEJA gas furnace. Verify your existing igniter's mounting configuration and OEM part number 332505-751 on your unit's service label before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required. Order today and get same-day shipping on all in-stock parts.
