Defective Door Switch — door switch senses door has been open for more than 1 hour continuously.

First step from the service manual

Check door switch operation; door SW sensing function is deleted when in error. Error clears when door SW open-close is sensed.

What door means on a Daewoo refrigerator

The "door" error code on a Daewoo refrigerator indicates that the door switch has detected the refrigerator door in an open position for more than one continuous hour. The door switch is a small electromechanical sensor, typically a plunger-style or magnetic switch, that signals the control board whether the door is open or closed. When the control board logs more than 60 minutes of uninterrupted open-door status, it flags this error and disables the door switch sensing function until the condition is resolved.

The most important behavior to understand is what happens once the error is active: the control board stops reading input from the door switch entirely. This means interior lights, fan delays, and any other functions tied to door state awareness will not operate normally until the error clears. The error will automatically clear once the control board detects a complete open-to-closed cycle from the door switch, meaning the switch must physically register both an open and a closed state in sequence.

Common causes include a door left physically open, a door that is not sealing completely due to a worn gasket or obstruction, a mechanically stuck or failed door switch, or wiring issues in the switch circuit. Because the error disables switch sensing while active, a technician should first confirm whether the door was genuinely left ajar before assuming component failure. If the door has been properly closed and the error persists, hands-on inspection of the switch and its wiring is the appropriate next step.

Common causes of door

  1. 01

    Door physically left open

    Wiring / connection

    The most straightforward cause is that the refrigerator door was genuinely left ajar for over an hour. Check whether the door is fully closed and latching properly before investigating any components.

  2. 02

    Worn or damaged door gasket

    Part replacement

    A deteriorated or compressed door gasket may prevent the door from sealing completely, causing the door switch to remain in the open-sensing position even when the door appears closed. Inspect the gasket around the full perimeter for tears, gaps, or areas that no longer make firm contact.

  3. 03

    Stuck or failed door switch

    Part replacement

    The door switch itself may be mechanically stuck in the open position or have an internal electrical failure. Test the switch for proper actuation and continuity; a faulty switch will not register the open-to-closed transition needed to clear the error.

  4. 04

    Wiring fault in the door switch circuit

    Wiring / connection

    Damaged, loose, or corroded wiring between the door switch and the control board can cause the board to read a constant open-door signal. Inspect the connector and wire harness at the switch for signs of damage or poor contact.

  5. 05

    Obstruction preventing full door closure

    Wiring / connection

    Food containers, shelves, or ice buildup near the door seal can physically block the door from closing completely. Check the interior for any items protruding into the door path and clear any frost or ice around the door frame.

Frequently asked questions about door

What does door mean on a Daewoo refrigerator?
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.
How do I fix the door error on a Daewoo refrigerator?
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.
Will resetting the refrigerator clear the door error code?
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.
Is the door error on a Daewoo refrigerator a safety concern?
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.
How much does it cost to fix a door switch error on a Daewoo refrigerator?
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.
