Possible Causes
Faulty fast-freeze button or switch, LED indicator failure, Main PCB not entering fast-freeze mode, Wiring fault between UI and PCB
How to Fix / Troubleshooting
Safety: Unplug the freezer before accessing the control panel.
- Check indicator: Press the fast-freeze button and listen for a change in compressor sound. If the function works but the light does not, the LED may be faulty.
- Test button: On mechanical models, test the fast-freeze switch for continuity when pressed. Replace if open.
- Inspect wiring: Ensure the fast-freeze button wiring or ribbon cable is securely connected to the main PCB.
- PCB function: If the button and wiring are good but the mode never engages, the main control board may be faulty and require replacement.
