Most common repairs needed to fix a Samsung refrigerator

PCB Replacement

A malfunctioning printed circuit board (PCB) could be the reason your refrigerator light is blinking and not cooling. The PCB controls all the electronic functions of the refrigerator, including temperature regulation and lighting. If the PCB is faulty, it may send incorrect signals or fail to power essential components, leading to a blinking light and inadequate cooling. You might notice the refrigerator interior is warm, and the light continuously blinks as an error indicator. If you suspect the PCB is at fault, schedule an in-home repair appointment through Sears Home Services to have a technician diagnose and replace the faulty PCB, ensuring your refrigerator cools properly and the light functions correctly.

Compressor Replacement

The compressor is essential for circulating refrigerant and maintaining the cold temperatures inside the refrigerator. If the compressor is locked or malfunctions, it may fail to start or run inefficiently, leading to a rise in temperature and triggering the blinking light as a warning signal. You might notice the refrigerator interior is warm and the compressor is unusually quiet or making strange noises. Schedule an in-home repair appointment through Sears Home Services to have a technician inspect your refrigerator if you suspect the compressor is at fault.

Compressor Start Relay Replacement

A failed compressor start relay could be the reason your refrigerator light is blinking and not cooling. The start relay helps the compressor start and run efficiently, which is crucial for maintaining the refrigerator's cooling function. If the start relay is malfunctioning, the compressor may fail to start or run intermittently, leading to a warm refrigerator interior and a blinking light indicating an error. You might notice the compressor attempting to start but repeatedly clicking off. To address this issue, inspect the start relay for any signs of damage or wear. If you suspect the start relay is at fault, schedule an in-home repair appointment through Sears Home Services to have a technician diagnose and replace the faulty start relay, ensuring your refrigerator cools properly and the light stops blinking.

Sears Home Services recommendations for a refrigerator light blinking and not cooling problem

When a refrigerator light blinks and it's not cooling, it can be for many reasons. To avoid replacing unneeded parts, we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of refrigerator failures.

What to look out for with a refrigerator light blinking and not cooling diagnosis

Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your refrigerator problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
