Daewoo Refrigerator Error Code dr

The DR error code on a Daewoo refrigerator indicates a fault with the R-Door Switch, which is the door switch located on the refrigerator compartment. This switch is responsible for detecting whether the refrigerator door is open or closed. When the control board receives a continuous open-door signal from this switch for more than one minute without interruption, it registers the DR fault. At that point, functions dependent on door-switch sensing, such as interior lighting control and door-ajar alerts, are suspended by the system.

The most common cause of this error is a door switch that has failed mechanically or electrically. The switch may be stuck in the open position, have a broken actuator plunger, or have developed a faulty internal contact. Wiring issues between the switch and the control board, such as a loose connector, broken wire, or corroded terminal, can also produce a constant open-door signal that mimics a failed switch.

Importantly, the DR error is self-clearing. The code will automatically terminate as soon as the control board successfully detects an open-and-close cycle from the door switch. This makes the initial diagnostic step straightforward: manually open and close the refrigerator door while observing whether the switch actuates. If the error clears, the switch may have been temporarily stuck or misaligned. If the error persists regardless of door movement, the switch itself or its wiring circuit requires closer inspection and likely component replacement.
