How to Fix / Troubleshooting
Safety first: Unplug the freezer before removing the control panel.
- Check user settings: Confirm that super-freeze is being activated correctly according to the user manual and that the door is fully closed.
- Inspect control panel: Remove the front control fascia and check the super-freeze button for sticking or physical damage. Clean any spills or debris around the button.
- Check wiring: Ensure the button's connector is firmly attached to the control PCB and that there are no broken tracks or burnt components near the super-freeze circuit.
- Test function: After reassembly, plug in the freezer and try activating super-freeze again. Observe whether the indicator light and compressor behavior change.
If AL10 persists and the button and wiring are intact, the main control board may need replacement.
