Display shows Er 67; door switch or door open sensor error, interior lights or fans may not behave correctly.

Safety: Unplug the freezer before removing door switch assemblies.

Er 67 indicates the control is not seeing correct door status.

• Locate door switch/sensor: Typically in the door frame or hinge area.
• Check magnet alignment: Ensure the door magnet lines up with the reed sensor when closed.
• Test switch: For mechanical switches, press and release while checking continuity with a multimeter. Replace if intermittent or open.
• Inspect wiring: Look for broken wires in the hinge area.

If Er 67 persists with a good switch/sensor, the main PCB input may be faulty and require professional service.
