The Carrier 311213-402 Collector Box is a critical combustion component designed for high-efficiency condensing gas furnaces. Engineered to manage the discharge of corrosive condensate and flue gases from the secondary heat exchanger, this OEM replacement part ensures the integrity of the secondary drainage system. Improper drainage or cracked collector boxes often lead to pressure switch trip-outs or rollout issues, necessitating a direct match for the furnace's serial and model number. This specific HVAC inducer assembly component is constructed from high-quality, heat-resistant composite materials to withstand constant exposure to combustion byproducts. For field technicians, verifying the furnace secondary heat exchanger compatibility and ensuring a leak-proof seal during installation is essential for maintaining proper draft induction and AFUE efficiency. Replacing a compromised collector box restores the critical pressure differential required for safe furnace operation and prevents moisture-related damage to the internal cabinet.

Key Benefits:

• Ensures peak combustion efficiency by providing a reliable path for condensate management.
• Matches exact OEM technical specifications for a seamless fit within the inducer motor assembly.
• Durable composite construction prevents leaks that can cause electrical damage or premature component failure.
• Restores the system's static pressure balance, resolving common airflow and ignition circuit faults.

Common Questions:

Will this collector box fix a pressure switch error?
If the Carrier 311213-402 Collector Box is cracked or clogged with sediment, it will disrupt the vacuum needed to close the pressure switch. Replacing a faulty box is a standard solution for furnace pressure switch failure related to the secondary heat exchanger.

Does this include the gasket for installation?
Technicians should verify if the existing gasket is reusable or if a separate condensate collector box gasket is required, as a perfect seal is mandatory to prevent CO leaks and moisture issues.

How do I know if the collector box is leaking?
Look for water pooling in the burner compartment or signs of white calcification (corrosion) on the exterior of the box. Any visible hairline cracks in the plastic housing require immediate replacement to maintain HVAC system safety.
