Daewoo Refrigerator Error Code dr

The DR error code on a Daewoo refrigerator indicates that the refrigerator door switch (R-Door Switch) is defective or is reading the door as open continuously for more than one minute. The control board suspends door-sensing functions when this fault is active. The error clears automatically once the system successfully detects a door open-and-close cycle.

The DR error itself does not indicate a dangerous condition, but a faulty door switch can affect the refrigerator's ability to monitor whether the door is properly closed. This could lead to temperature issues if the door is actually being left open or is not sealing correctly. Address the error promptly to ensure the refrigerator is maintaining safe food storage temperatures.

If only the door switch needs replacement, the part itself typically costs in the range of $10 to $40 depending on availability. If a technician is needed for diagnosis and installation, total repair costs including labor generally fall in the range of $75 to $200. Wiring repairs or gasket replacements, if needed, may add to that estimate.

Start by opening and closing the refrigerator door several times to see if the error clears on its own. If it does not, inspect the door switch for a stuck or broken actuator plunger, and check the wiring connector at the switch for looseness or corrosion. If the switch is confirmed defective, it will need to be replaced. Also check that the door is closing properly and that the gasket is not preventing full contact with the switch.

A simple power reset may temporarily clear the display, but the DR error is designed to clear automatically once the control board detects normal door switch operation, meaning a successful open-and-close cycle. If the underlying switch or wiring fault is not corrected, the error will return. Resetting without addressing the root cause is not a lasting solution.
