Bosch Refrigerator E411 Error Code

The compressor is not starting, leading to no cooling.

Common causes

  • Defective start relay or capacitor
  • Compressor internal fault
  • Main board failure

How to fix it

  1. Unplug the refrigerator and listen for a click when restarting; if no click, relay may be bad.
  2. Check the start relay and overload protector for continuity.
  3. Test the compressor windings for shorts or open circuits.
⚠ When to call a pro: If the relay is good and compressor still doesn't start, call a professional technician.
