E8 error; alarm may sound and internal light may not work correctly

Safety: Unplug the freezer before testing or replacing the door switch.

Steps to fix E8:

• 1. Check door closure: Ensure the door closes fully and the gasket is not obstructing the switch area. A partially open door can mimic a switch fault.
• 2. Locate the door switch: On many Caple freezers, the switch is in the cabinet frame near the top or side, or integrated as a magnetic sensor behind the liner.
• 3. Test the switch: For a mechanical plunger switch, press it by hand and listen for a click; test continuity with a multimeter (closed when pressed). For a magnetic reed switch, place a magnet near the sensor and test continuity.
• 4. Inspect wiring: Check the harness from the switch to the control PCB for damage, especially near hinge areas where wires may flex.
• 5. Replace faulty switch: Pop out or unscrew the old switch, connect the new one, and secure it in place. For magnetic systems, ensure the door magnet aligns correctly with the sensor.
• 6. Verify operation: Restore power and confirm that the interior light and door alarm behave normally and that E8 clears.

Tip: A faulty door switch can also prevent the evaporator fan from running on some models, affecting cooling.
