What Er rS Means on a Kenmore Freezer
The Er rS error code indicates a refrigerator sensor error on combination refrigerator-freezer units. The temperature sensor in the refrigerator compartment (not the freezer section) has failed or is misreading.
What You Can Do
- Check if the refrigerator section is maintaining normal temperatures (35–38°F).
- Unplug and reset — if error clears, monitor closely.
- Sensor replacement is a straightforward technician repair.
