Freezer shows F2 and interior light or fan may not operate correctly when door is opened.

Safety: Disconnect power before working on switches or wiring.

Steps:

• 1. Check door switch function: Press the switch manually and observe if the interior light turns on/off (after restoring power briefly). If not, suspect the switch or wiring.
• 2. Remove switch: Unplug the freezer. Pry out the switch from the liner and inspect the terminals and wires.
• 3. Test continuity: Use a multimeter to check the switch in both pressed and released positions. Replace if it does not change state.
• 4. Inspect harness: Follow the wires from the switch into the cabinet as far as accessible. Look for pinched or broken insulation.
• 5. PCB input: If the switch and wiring are good, the main PCB door input circuit may be faulty and require board replacement.
