Carrier 343314-75101 Drain Pan

The Carrier 343314-75101 Horizontal Drain Pan is a critical OEM HVAC replacement part engineered for precise condensate management in horizontal fan coil and furnace applications. Designed to replace legacy part numbers 322023-703, 321884-401, and 321894-706, this pan ensures a factory-spec fit for select Carrier, Bryant, and Payne air handlers. When a clogged HVAC drain pan or a cracked condensate pan leads to moisture bypass, replacing the assembly with this durable, corrosion-resistant component is essential to maintain cabinet integrity and prevent secondary water damage. This unit is built to withstand thermal cycling and provides the exact pitch required for efficient gravity drainage in horizontal HVAC installations. As a Genuine Carrier Part, it offers the structural rigidity needed to support the evaporator coil while maintaining clear drainage paths for high-efficiency cooling systems.

• Universal Compatibility: Serves as the official condensate drain pan replacement for multiple older Carrier generations.
• Structural Integrity: High-grade composite material resists the cracking and warping common in aftermarket alternatives.
• Precision Drainage: Engineered with the correct slope to prevent standing water and microbial growth within the plenum.
• Reduced Callback Risk: Using factory-authorized parts ensures the primary and secondary drain ports align perfectly with existing PVC lines.

Is the Carrier 343314-75101 compatible with my specific air handler?
This pan is designed for horizontal-flow configurations. You should verify the dimensions and coil mounting points against your existing 342023-703 or 321894-706 part numbers to ensure a drop-in fit.

Does this pan include the drain plugs and gaskets?
This is the primary pan assembly. We recommend inspecting your existing drain line fittings and primary/secondary plugs, as these often require cleaning or replacement during a pan swap.

Why should I Choose an OEM pan over a generic plastic universal pan?
OEM pans are molded to the exact footprint of the evaporator coil. Generic pans often lack the necessary support baffles, which can lead to air bypass or improper drainage that damages the furnace heat exchanger or floor joists.
