Error code 67 is displayed. The door alarm may sound and cooling performance may be affected.

Safety first: Unplug the refrigerator before testing switches or removing trim.

Steps:

• 1. Identify the affected door: The code may correspond to a specific door (e.g., left fresh food, right fresh food, freezer). Check which door light or alarm behaves incorrectly.
• 2. Test the door switch: Locate the door switch plunger or magnetic reed switch. Press it manually and see if the interior light turns on/off (when briefly powered). If not, the switch may be bad.
• 3. Continuity test: Unplug the unit. Remove the switch from the liner (usually pries out). Disconnect the wires and test continuity with a multimeter while pressing and releasing the switch. Replace if it does not change state.
• 4. Inspect the door harness: On some French-door models, door position is sensed via a harness in the hinge. Inspect for pinched or broken wires at the hinge area.
• 5. Replace the faulty switch or repair the harness: Install a new OEM door switch or repair/replace the damaged harness.
• 6. If switches and harness are good: The main control board may be misreading the door status and could require replacement.
