Kenmore Refrigerator Error Code Er FS: Meaning and Fix
Reading the refrigerator display
On a refrigerator the code shows on the control panel or dispenser display. Some models flash a letter or alternate two characters; hold the code in view and note both. Check the model-number prefix first: the same Kenmore code can mean different things depending on the manufacturer.
Kenmore is a private label, and the factory that built your unit decides which fault codes it shows. The first digits of a Kenmore model number (110, 417, 665, 795, 796 and so on) tell you whether Whirlpool, LG, Electrolux or Frigidaire made it. Check the model label on your unit before using any chart.
What causes Er FS

- A control board input that misreads the sensor signal

- Inspect the sensor, its lead wire and plug for damage, moisture or corrosion; clean contacts and reseat the connector.
- Inspect the harness for damage.

Questions
What does error Er FS mean on a Kenmore refrigerator?
The freezer temperature sensor is open or shorted. Kenmore sells units built by several manufacturers, so the code table that applies depends on who made your model; use the model number to confirm.
Can I keep using my refrigerator while Er FS is showing?
Often yes for a short while, but with reduced performance because the control is running blind; get it checked before it causes a heating or flooding problem.
How do I clear Er FS, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
