5421JJ1001B – Genuine OEM LG Refrigerator Evaporator Assembly

The 5421JJ1001B Genuine OEM LG Evaporator Assembly is an original LG replacement component designed for compatible refrigerators. This evaporator functions as a heat exchanger within the refrigerator’s sealed refrigeration system, absorbing heat to support proper cooling and freezing performance.

Manufactured to LG’s original equipment specifications, this assembly is intended to restore cooling performance when the original evaporator is damaged or defective. It is also listed for select Kenmore refrigerator applications manufactured by LG. Before ordering, verify compatibility using your complete refrigerator model number.

Appliance Kingdom serves homeowners, landlords, property managers, and appliance repair technicians across Canada, with Canada-wide shipping and support to help identify the correct replacement part.

Function & Importance of the Evaporator Assembly

The evaporator is a key component of a refrigerator’s refrigeration system. Refrigerant circulates through the evaporator, absorbing heat from inside the appliance and allowing the refrigerator and freezer compartments to maintain their required temperatures.

A correctly specified evaporator assembly is essential for effective heat transfer, reliable cooling, and proper operation of the sealed refrigeration system. Using the correct genuine OEM component helps maintain the intended fit and system compatibility.

When the evaporator becomes damaged or develops a refrigerant leak, the refrigerator may struggle to maintain its temperature. Cooling performance can decline, food may not remain sufficiently cold, and the compressor may run for extended periods.

Common Symptoms of a Faulty Refrigerator Evaporator

A defective evaporator assembly may be associated with the following symptoms:

• Refrigerator compartment is too warm.

• Freezer compartment is too warm.

• Refrigerator or freezer becomes excessively cold due to a temperature-control or related system issue.

• Refrigerator runs for unusually long periods.

• Cooling performance becomes inconsistent.

• The appliance struggles to maintain the required temperature.

These symptoms do not automatically confirm an evaporator failure. Refrigerant leaks, compressor problems, airflow restrictions, fan failures, defrost issues, and other refrigeration-system faults can produce similar symptoms.

Will replacing the evaporator fix my refrigerator?

Replacing the evaporator can restore normal cooling when a technician confirms that the evaporator is defective and identifies no unresolved underlying problems. A professional diagnosis is recommended before ordering this component.

Installation Overview

Replacing an evaporator assembly is an advanced refrigerator repair and is not recommended as a routine DIY project.

The repair involves accessing the sealed refrigeration system, recovering refrigerant using appropriate equipment, replacing the component, and completing the required leak checks, evacuation, and refrigerant recharge in accordance with manufacturer procedures.

A qualified refrigeration technician should perform this repair. Incorrect handling of refrigerant or the sealed system can cause equipment damage, safety risks, and poor cooling performance.

Always disconnect electrical power and follow applicable service and refrigerant-handling requirements.
