E11
Bosch Refrigerator
Severity: ModerateWhat Does This Error Mean?
The E11 error means your Bosch refrigerator's fresh food sensor has failed. This sensor monitors the temperature inside the main fridge compartment. Without it, the fridge can't regulate cooling correctly.
Affected Models
- Bosch Series 4 Refrigerator
- Bosch Series 6 Refrigerator
- Bosch Series 8 Refrigerator
- Bosch Benchmark Series Refrigerator
Common Causes
- Faulty or damaged fresh food compartment temperature sensor
- Loose or disconnected sensor wiring harness
- Moisture or ice buildup shorting the sensor
- Control board failure causing false sensor reading
- Physical damage to the sensor from impact or vibration
How to Fix It
-
Unplug the refrigerator from the wall outlet.
Wait at least 5 minutes before doing anything else. This resets the control board.
-
Plug the refrigerator back in and check if E11 is still showing.
A temporary glitch can sometimes trigger this code. A reset often clears it.
-
Check inside the fresh food compartment for heavy ice buildup near the back wall.
Ice around the sensor can cause false readings. Defrost manually if needed by unplugging for 24 hours with the doors open.
-
Locate the fresh food temperature sensor — it is usually clipped to the back wall inside the fridge compartment.
Check that the sensor's wire connector is firmly plugged in. Push it in until you feel a click.
-
If the sensor connection looks fine, the sensor itself may need to be replaced.
Search for your model number (on the door frame sticker) plus 'E11 temperature sensor' to find the correct part.
When to Call a Professional
Call a technician if replacing the sensor yourself doesn't clear the error. A faulty control board will need professional diagnosis and replacement.
Frequently Asked Questions
Is my food safe while the E11 error is showing?
It depends on how long the fridge has been struggling. If the fridge still feels cold, food is likely fine for now. Check that the temperature inside is 40°F (4°C) or below using a thermometer.
Can I fix E11 myself without a technician?
Yes, in many cases. A power reset or reconnecting a loose sensor wire often resolves it. If the sensor itself is faulty, replacing it is a manageable DIY repair.
How much does it cost to fix a Bosch E11 error?
A replacement temperature sensor usually costs $20–$50 for the part. If a technician is needed, expect a service call fee of $80–$150 plus parts. The control board, if at fault, costs significantly more.
