Kenmore Freezer Error Er FS

Kenmore Freezer

High Severity
Warning: If your Kenmore appliance displays the Er FS error code and you are unsure how to proceed, turn off the appliance and contact a qualified technician. Some errors require professional repair to avoid further damage or safety risks.

What Er FS Means on a Kenmore Freezer

The Er FS error code indicates a freezer temperature sensor (thermistor) failure. The control board is not receiving a valid temperature reading from the freezer compartment sensor.

Common Causes

  • Open or short in the thermistor
  • Wiring harness damage (often from ice buildup or rodent damage)
  • Main control board fault

What You Can Do

  1. Check if the freezer is maintaining temperature — if it is, this may be a sensor error only.
  2. Unplug for 10 minutes and restart.
  3. A technician can test thermistor resistance and replace it if needed.

Urgency

Without a working temperature sensor, the freezer cannot regulate itself properly. Food safety is at risk — have this repaired promptly.
