Daewoo Refrigerator Error Code door

The door error code on a Daewoo refrigerator means the door switch has detected the door in an open state for more than one continuous hour. When this threshold is reached, the control board logs the error and suspends normal door switch sensing. The error will clear automatically once the switch registers a complete open-to-closed cycle, meaning the door is properly shut and the switch actuates normally.

A simple power reset will not permanently clear this error if the root cause is still present. The control board is specifically designed to clear the door error only when it detects the door switch cycling from open to closed. If the switch is faulty or the door is still not sealing, the error will return even after a power cycle.

If the issue is simply a door left open or a minor obstruction, there is no parts cost involved. Replacing a worn door gasket typically costs between $20 and $60 for the part alone, depending on the model. A replacement door switch is generally in the $10 to $40 range for the part, with professional labor adding $75 to $150 or more depending on your location and the technician.

Start by confirming the door is fully closed and latching properly, and check for any obstructions or a damaged gasket preventing a complete seal. If the door appears fully closed but the error persists, inspect the door switch for mechanical sticking or electrical failure and check the wiring harness for loose or corroded connections. The error clears automatically once the control board senses the door switch transitioning from open to closed, so no manual reset is required if the underlying issue is resolved.

An open door for over an hour means the refrigerator interior has been exposed to ambient temperature, which can allow perishable food to enter unsafe temperature ranges. Additionally, while the error is active, the door switch sensing function is disabled, meaning the control board cannot monitor door state normally. It is important to resolve the error promptly to restore proper food safety conditions and normal appliance operation.
