Daewoo Refrigerator Error Code Eu
Full ice sensing switch error
Full ice sensing switch error - switch that senses if ice is full is in error.
First step from the service manual
When dropping ice, the motor just rotates 90 degrees. Terminates when switch is normal.

What Eu means on a Daewoo refrigerator
The Eu error code on a Daewoo refrigerator indicates a fault with the full ice sensing switch, which is the component responsible for detecting when the ice bin has reached its capacity. This switch communicates with the ice maker control system to stop ice production once the bin is full. When the switch fails or sends an unexpected signal, the refrigerator logs the Eu code and interrupts normal ice-making operations.
The primary diagnostic behavior tied to this error is observable during ice dispensing: instead of completing a full rotation cycle, the auger motor only rotates approximately 90 degrees before stopping. If the full ice sensing switch is functioning correctly, the system terminates this test rotation as expected. If the motor stops at 90 degrees outside of normal operation, or the switch fails to signal properly during the drop cycle, the control board interprets this as a switch error and triggers the Eu code.
Common causes include a physically stuck or jammed switch due to ice buildup around the sensor, a faulty switch that no longer opens and closes reliably, damaged wiring or connectors in the circuit between the switch and the main control board, or a misaligned ice bin that prevents the switch from actuating correctly. Addressing this error typically requires inspecting the switch mechanism, checking for ice obstructions, and testing continuity through the switch and its associated wiring harness.

Common causes of Eu
- 01
Ice buildup around the sensing switch
Wiring / connectionIce or frost accumulation can physically block or freeze the full ice sensing switch in place, preventing it from moving freely. Inspect the switch area for visible ice or frost and defrost the compartment if needed.
- 02
Faulty full ice sensing switch
Part replacementThe switch itself may have failed electrically and no longer opens or closes its contacts reliably. Test the switch for continuity with a multimeter through its full range of motion to confirm failure.
- 03
Damaged wiring or connector
Wiring / connectionThe wiring harness or connector between the full ice sensing switch and the control board may be broken, corroded, or loose, causing an intermittent or absent signal. Visually inspect and gently tug each connector to check for poor contact.
- 04
Misaligned or improperly seated ice bin
Wiring / connectionIf the ice storage bin is not seated correctly, the sensing switch may not be actuated at the right position during the ice drop cycle. Remove and reseat the ice bin, ensuring it is fully inserted and properly aligned.
- 05
Control board fault
Part replacementIf the switch and wiring both test correctly, the main control board may be failing to properly read the switch signal. This is a less common cause and is typically diagnosed after all other components have been ruled out.
