What dr means on a Frigidaire refrigerator
The dr error code on a Frigidaire refrigerator indicates that the control board has detected a door open condition lasting longer than one continuous hour. The door switch system relies on small plunger-style or magnetic switches mounted in the door frame or cabinet to signal the control board whenever a door is opened or closed. When the board stops receiving a "door closed" signal for more than 60 minutes, it logs the dr fault and typically activates an alert to prevent temperature loss and excessive compressor cycling.
The most direct cause of this fault is a defective door switch that has failed in the open-circuit position, causing the board to interpret the door as perpetually open even when it is physically closed. Beyond switch failure, the wiring harness connecting the switch to the control board can develop breaks, shorts, or corroded terminals that mimic a failed switch. In some cases, the door itself may be physically misaligned or the hinge may be worn, preventing the switch actuator from making proper contact when the door closes.
Diagnosing this code starts with physically inspecting and testing each door switch. A functioning switch should show continuity when depressed and an open circuit when released. If a switch tests out of specification or fails to change state, it should be replaced. The wiring between the switch and the control board should also be inspected for damage or loose connectors before condemning the switch itself.

Common causes of dr
- 01
Defective door switch
Part replacementThe door switch has failed internally and no longer sends a closed-door signal to the control board, even when the door is shut. Testing the switch for continuity while pressing the plunger will confirm whether it has failed.
- 02
Worn or damaged switch actuator
Part replacementThe plastic tab or button that physically presses the door switch can crack or break off over time, preventing the switch from registering a closed door. Inspect the actuator on the door or door frame for visible damage.
- 03
Damaged or corroded wiring harness
Wiring / connectionThe wiring connecting the door switch to the main control board can develop breaks, pinches, or corroded terminals that interrupt the signal. Inspect the harness along its full length and check all connectors for oxidation or looseness.
- 04
Door misalignment or worn hinge
Wiring / connectionIf the refrigerator door sags or does not close squarely due to a worn hinge or improper leveling, the switch actuator may not make full contact with the switch plunger. Check that the door closes evenly and that hinges are tight and undamaged.
- 05
Faulty main control board
Part replacementIf all door switches test correctly and the wiring harness is intact, the main control board itself may be misreading the switch input signal. This is a less common cause and should only be considered after ruling out the switches and wiring.
