Freezer shows error code F3 and the fast-freeze (super freeze) function does not work correctly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Defective fast-freeze button or switch, Faulty fast-freeze indicator circuit, Control board output failure, Wiring fault to fast-freeze relay

Safety first: Unplug the appliance before removing the control panel.

Check fast-freeze button: Press the button firmly and verify that the indicator light (if present) responds. If the button feels stuck or loose, the switch may be faulty.
Inspect control panel: Remove the panel and check for cracked solder joints or damaged tracks around the fast-freeze switch.
Power reset: Reconnect power and test the function again after a reset.

When to call a technician: If F3 remains and fast-freeze does not engage, the control board may require replacement.
