SZ4410 - Universal Supco Refrigerator Evaporator

SZ4410 – Universal Supco Refrigerator Evaporator

The SZ4410 Universal Supco Refrigerator Evaporator is an aftermarket refrigerator replacement component designed for compatible Sub-Zero refrigerator applications. Manufactured by Supco, a supplier of appliance replacement parts, this evaporator is intended to support the refrigerator's cooling system by providing the heat-exchange surface needed for refrigerant to absorb heat from inside the appliance.

The Supco SZ4410 evaporator measures approximately 28 × 20 × 1 inches and is identified in Supco replacement-part documentation as a replacement for select Sub-Zero evaporator assemblies. Appliance Kingdom serves customers across Canada with appliance replacement parts and compatibility support.

Important availability note: A supplier listing reports that SZ4410 was discontinued by the manufacturer on November 28, 2025. Confirm current stock and availability before purchasing.

Function & Importance of the Refrigerator Evaporator

The evaporator is a key component of a refrigerator's sealed refrigeration system. Refrigerant flows through the evaporator, absorbs heat from the refrigerator or freezer compartment, and helps maintain the low temperatures required for food preservation.

A correctly specified evaporator is essential for efficient heat transfer, reliable cooling performance, and proper operation of the refrigeration system. Incorrect dimensions or refrigerant connections can compromise system performance and lead to costly repairs.

Common Symptoms of a Faulty Refrigerator Evaporator

Problems involving the evaporator or its associated refrigeration components may produce symptoms such as:

• Refrigerator or freezer compartments failing to reach the correct temperature

• Insufficient cooling despite the compressor running

• Uneven cooling throughout the appliance

• Excessive frost or ice accumulation on the evaporator

• Longer-than-normal compressor run times

• Cooling performance that deteriorates over time

These symptoms do not automatically indicate a defective evaporator. Refrigerant leaks, restricted refrigerant flow, compressor problems, defrost-system faults, and evaporator fan failures can cause similar issues.

Will Replacing SZ4410 Fix My Refrigerator?

Replacing the evaporator can restore cooling performance when the original evaporator is confirmed to be defective, leaking, damaged, or otherwise unable to perform correctly. However, the refrigeration system should be professionally diagnosed before ordering this component.

Because SZ4410 is a sealed-system component, replacement requires appropriate refrigeration tools, refrigerant-handling expertise, and system testing.

Installation Overview

Evaporator replacement is an advanced refrigeration repair and is not generally recommended as a routine DIY project.

The repair may involve recovering refrigerant, opening the sealed refrigeration system, removing and installing refrigerant lines, brazing, leak testing, evacuating the system, and recharging it to the manufacturer's specifications.

Installation should be performed by a qualified refrigeration technician who follows applicable Canadian refrigerant-handling and safety requirements.
