Replacing one of these refrigerator parts may fix your problem.

Compressor Replacement

A refrigerator compressor that is locked might display various symptoms. The most noticeable symptom is a lack of cooling in the refrigerator compartment, which can lead to increased temperatures and food spoilage. The freezer may also struggle to maintain freezing temperatures, resulting in no ice production from the icemaker. You may observe that the compressor is unusually quiet or fails to emit its typical humming sound during operation. Sometimes, the compressor may attempt to start but fail, resulting in repeated clicking sounds. The compressor's inability to circulate refrigerant properly can disrupt the defrosting process, leading to ice accumulation in the freezer. Moreover, a defective compressor could cause a sudden influx of melting frost into the drain line, leading to blockages, inadequate drainage, and potential water leaks.

Troubleshooting compressor problems in refrigerators

Electronic Control Board Replacement

A malfunctioning electronic control board in a refrigerator can lead to various issues, such as power loss, cooling inefficiencies, and water leakage. This is because the board serves as the central control unit of the refrigerator, overseeing vital functions like temperature regulation, fan operation, defrost cycles, icemaker functionality, and dispenser operations. When the board malfunctions, it can disrupt communication among different components, including automatic door mechanisms if present. A defective board may produce clicking or chattering sounds and emit a burning odor. Given its potential impact on multiple components, it's prudent to have a Sears Home Services professional evaluate the board through diagnostic tests to determine if replacement is necessary.

Evaporator Replacement

When the refrigerator's evaporator is defective, it can lead to a decrease in overall cooling performance, causing temperatures to rise in both the refrigerator and freezer compartments. This temperature increase may lead to food spoilage and ineffective preservation of frozen items. Frost or ice buildup on the evaporator coils can hinder their ability to absorb heat efficiently. Excessive condensation inside the refrigerator may result in leaks. Additionally, a damaged evaporator may produce unusual noises such as hissing or gurgling sounds during the refrigeration cycle.
