Carrier 339707-751-CBP Kit
The Carrier 339707-751-CBP Collector Box Kit is a critical OEM replacement component designed for 35-inch high-efficiency condensing gas furnaces. As a factory authorized part, this kit is engineered to maintain the performance of 90% AFUE furnaces by effectively managing condensate collection and distribution. Over time, plastic collector boxes can warp, crack, or leak due to thermal stress and chemical exposure from the combustion process. Replacing a compromised unit with this genuine Carrier furnace collector box ensures that your pressure switches close correctly and prevents potential condensate leaks that can damage other internal electronics or the secondary heat exchanger.
This comprehensive kit includes the collector box, mounting screws with washers, and all necessary gaskets—specifically the inducer housing drain gaskets and inlet gaskets—to ensure a factory-standard seal. Designed for compatibility across Carrier, Bryant, and Payne models, it replaces previous part numbers such as 347318-751-CBP and 336850-751-CBP. For installation, always use a non-powered screwdriver to reach the recommended 21 lb-in torque in an alternating pattern, preventing over-tightening of the plastic flange. This HVAC replacement part is essential for restoring heating reliability and maintaining the structural integrity of the furnace's venting system.
Key Benefits- Broad Compatibility: Fits specific cabinet widths for Carrier, Bryant, and Payne 35-inch high-efficiency condensing furnaces.
- Complete Installation Package: Includes essential inducer housing gaskets and specialized hardware for a secure, airtight fit.
- Direct Fit OEM Quality: Maintains the original factory specifications for negative pressure requirements, ensuring reliable pressure switch operation.
- Critical Leak Prevention: Replaces cracked or warped boxes to stop condensate from leaking onto the blower shelf or furnace floor.
How do I know if the collector box needs replacement?
Watch for water pooling at the base of the furnace or rhythmic "tripping" of the pressure switch. Visual inspection often reveals hairline cracks in the plastic or mineral deposits along the seams where the box meets the heat exchanger.
Does this kit include the gaskets?
Yes, it includes the primary collector box gasket and the manual's specified drain and inlet gaskets for the inducer assembly, ensuring you don't have to source them separately on the job site.
Can I use a sealant instead of replacing the box?
Sealants are generally considered temporary. Since the collector box operates under negative pressure and handles corrosive condensate, a full replacement with a genuine Carrier part is the standard professional practice to ensure long-term reliability.
