Common refrigerator repair parts you may need
Replacing one of these refrigerator parts may fix your problem.
Defrost Heater Replacement
A malfunctioning refrigerator defrost heater can trigger the buildup of frost or ice on the evaporator coils, which reduces cooling efficiency. This occurs because the defrost heater fails to melt the frost during its designated cycles. As a result, both the refrigerator and freezer compartments experience elevated temperatures. Furthermore, a faulty defrost heater may overheat, causing the accumulated frost or ice to scorch and emit a burning odor. This burning smell becomes a significant concern. Moreover, the effectiveness of the defrost cycle diminishes, leading to persistent frost buildup and potentially more severe issues with the refrigerator's cooling system over time.
Electronic Control Board Replacement
A failed electronic control board can lead to a variety of failures in a refrigerator, including a lack of power or cooling and water leaking. This is because the board acts as the brain of the refrigerator, controlling operations such as regulating internal temperatures, running fans, managing defrost cycles, overseeing the icemaker, and controlling dispenser functions. If the electronic control board is defective, it can disrupt communication between many different components, including automatic doors if equipped. A malfunctioning board may cause a chattering or clicking noise from the refrigerator and may emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.
Compressor Motor Bearing Replacement
When a compressor motor bearing is worn, you may notice increased noise during operation, such as grinding or squealing sounds, an indication of friction and wear on the bearing. There may be a burning smell, and you also might hear an intermittent buzzing or humming noise, especially when the compressor starts or stops. Over time, a worn bearing will cause the compressor to seize. It's imperative to have a Sears Home Services professional address these symptoms promptly to prevent further damage to the compressor.
