Nordyne 355480R Close Off
The Nordyne 355480R Close Off Left Side Coil is an essential OEM replacement panel designed specifically for Nordyne evaporator coil housings found in residential and manufactured housing furnace applications. As a veteran technician knows, maintaining the structural integrity of the coil cabinet is critical for managing static pressure and ensuring high-efficiency airflow across the A-coil or microchannel heat exchanger. This left side close off panel seals the gaps between the internal coil and the exterior cabinet, preventing untreated air bypass that can lead to evaporator icing or reduced cooling capacity in Nortek HVAC systems. Manufactured from heavy-gauge galvanized steel to meet original factory specifications, the 355480R ensures a precise fit for upflow and horizontal furnace configurations. Using genuine Nordyne furnace parts like this close off maintains the UL listing of the equipment and prevents the common "whistling" noises associated with improper air seals in high-velocity duct systems.
Key Benefits- Optimized Static Pressure: Eliminates air bypass to maintain consistent CFM across the coil surface for maximum heat transfer.
- OEM Precision Fit: Direct replacement for Nordyne 355480R, ensuring screw holes line up perfectly with the existing coil cabinet.
- Enhanced System Efficiency: Improves SEER2 performance by ensuring all return air is directed through the evaporator fins rather than around them.
- Durable Construction: Made from corrosion-resistant material to withstand the high-moisture environment of a cooling coil.
Is this close off panel compatible with right-hand return configurations?
No, the 355480R is specifically engineered for the left side of the coil. For right-hand applications, a different part number is required to ensure proper alignment with the refrigerant lines and drain pan.
Will this part help with furnace high-limit tripping?
Yes, by sealing air leaks at the evaporator coil, you ensure proper airflow volume reaches the heat exchanger, which can help prevent overheating issues caused by low static pressure or air bypass.
Does this fit Intertherm or Miller mobile home furnaces?
Yes, as these brands are manufactured by Nortek (Nordyne), this close off is compatible with many CMF and M1 series coil cabinets that utilize the 355480R specification.
