LG Refrigerator Error Code dr

The dr code on an LG refrigerator means the control board has detected that the refrigerator door has been open, or appears to be open, for more than one continuous hour. It points to either a door that is physically ajar or a defective door switch that is incorrectly signaling an open-door condition. The first step is always to check whether the door is actually closed all the way.

A power reset may temporarily clear the dr code, but if the underlying problem, such as a faulty door switch or a damaged wiring harness, has not been repaired, the code will return once the control board detects the open-door condition again. Resetting is useful for confirming whether the error is persistent, but it is not a fix on its own.

Repair costs depend on the root cause. If the issue is simply a misaligned door or a worn gasket, costs are relatively low, typically ranging from $20 to $80 for a replacement gasket plus labor if a technician is involved. A faulty door switch is generally an inexpensive part, often in the $15 to $50 range, though labor adds to the total. Control board replacement, if needed, is the most expensive outcome and can range from $150 to $400 or more depending on the model.

Start by making sure the door is fully closed and that no food items or shelving are preventing it from sealing. If the door is closed properly, inspect the door gasket for damage and test the door switch for continuity. If the switch has failed, it will need to be replaced. Also check the wiring harness at the hinge area for any breaks or loose connectors.

The dr code is not an immediate safety hazard, but it does indicate that the refrigerator is not maintaining a sealed environment. A prolonged open-door condition causes temperature rise inside the cabinet, which can lead to food spoilage. It also forces the compressor to run more frequently, increasing energy use and wear on the system. Addressing the code promptly is recommended.
