Freezer shows E6 and interior light or fan may not operate correctly; control panel may be unresponsive.

Safety: Disconnect power before removing the door switch or control panel.

Steps:

• Locate the door switch: On most Westinghouse freezers, the switch is in the door frame near the top or side, activated by the door closing.
• Check operation: Press the switch plunger by hand. The interior light should turn on/off (if power is temporarily restored for this test). If not, unplug again and continue.
• Remove and test switch: Pry the switch out carefully with a plastic tool. Disconnect the wires and test continuity with a multimeter. The switch should change from open to closed when pressed.
• Inspect wiring: Look for loose connectors or broken wires in the door frame area.
• Replace faulty switch: Install a new OEM Westinghouse door switch. Ensure wires are firmly connected and the switch snaps securely into the frame.
• If switch and wiring are good: The control board input circuit may be defective and require replacement.
