Er-rS Dilemma: Solving Kenmore Refrigerator Sensor Problems

Experiencing Kenmore Refrigerator Sensor Problems? The Er-rS error code can be frustrating, but don’t worry! In this comprehensive guide, we’ll dive into what causes this error, how to troubleshoot it, and what preventative measures you can take to avoid it in the future. Let’s get started!

🔗 Kenmore Refrigerators are known for their reliability and performance, but like any appliance, they can encounter issues. One such issue is the Er-rS error code, which indicates a problem with the refrigerator’s sensor(s).



The Er-rS error code appears when there’s a problem with one or more of the sensors in your Kenmore refrigerator. These sensors are responsible for monitoring and controlling various functions, such as temperature and humidity. When the sensors fail or malfunction, the refrigerator may not operate efficiently, leading to food spoilage and wasted energy.

In this guide, we’ll walk you through the steps to identify and resolve Kenmore Refrigerator Sensor Problems and get your fridge running smoothly again.


Causes of Er-rS Error

There are several reasons why your refrigerator might display the Er-rS error code:

  1. Faulty Sensor: The sensor responsible for monitoring the temperature or humidity might be defective or malfunctioning.
  2. Loose Wiring Connections: The wiring connecting the sensors to the main control board could be loose or disconnected.
  3. Faulty Control Board: The main control board, which processes the sensor data, might be malfunctioning.


Troubleshooting Steps

Here are some steps to help you troubleshoot and resolve the Er-rS error:

  1. Inspect the sensors: Locate the sensors in your refrigerator (refer to your user manual for their locations) and inspect them for any visible damage. If a sensor appears damaged, replace it with a new one.
  2. Check the wiring connections: Inspect the wiring connecting the sensors to the control board. Ensure they are securely connected and free of any visible damage. If you find any loose connections, reattach them properly.
  3. Test the control board: If the sensors and wiring connections appear to be in good condition, the issue might be with the control board. Contact a professional technician to diagnose and repair the control board if necessary.
