Carrier 311213-401 Collector Box
The Carrier 311213-401 Collector Box is a critical OEM replacement part designed for high-efficiency condensing furnaces. Engineered to meet precise factory tolerances, this cold end collector box manages the flow of acidic condensate, directing it from the heat exchanger to the drain system. Its durable composite construction is specifically formulated to withstand the corrosive nature of combustion byproducts, preventing leaks that lead to pressure switch trips or secondary heat exchanger damage. This component measures approximately 4.7 inches by 14.3 inches and is a direct fit for several Carrier, Bryant, and Day & Night furnace models, including the 398AAV and 398AAW series.
When you are troubleshooting a furnace condensate leak or a failure in the draft inducer housing, replacing a cracked or warped collector box is essential to restoring the airtight seal required for the combustion process. Using this genuine Carrier part ensures 100% compatibility with existing furnace drainage kits and preserves the design intent of the original heating system. For contractors looking to reduce callbacks and maintain peak AFUE ratings, verifying the integrity of the collector box gasket surfaces during installation is a professional best practice.
Key Benefits:- Ensures precise condensate management to prevent fluid buildup in the primary heat exchanger.
- Constructed from heavy-duty, heat-resistant polymers for long-term HVAC system reliability.
- Directly compatible with Carrier furnace parts, ensuring an airtight seal for the combustion blower assembly.
- Prevents common pressure switch errors caused by improper drainage or vacuum leaks.
What are the symptoms of a failing collector box?
Technicians typically observe water pooling at the base of the furnace cabinet or recurring 31 or 34 fault codes, often indicating that the collector box is cracked or clogged, disrupting the pressure switch circuit.
Does this part include the mounting gasket?
This SKU is the collector box assembly. It is standard practice to inspect the existing seal; however, a new 336839-401 gasket is often recommended to ensure a leak-proof installation during a full tear-down.
Can I use an aftermarket alternative?
While universal options exist, using a genuine OEM collector box like the 311213-401 is necessary to maintain the precise static pressure required by the inducer motor for safe exhaust venting.
