Safety: Disconnect mains power before accessing sensors or PCB.

Steps to address E11:

1. Try a control reset: Turn off the appliance at the mains for 10 minutes, then power back on. Attempt to toggle fast‑freeze mode via the control panel.
2. Locate fast‑freeze sensor: On some Caple freezers, a dedicated sensor is placed near the fast‑freeze section or shelf. Remove internal covers as needed to access it.
3. Inspect and test sensor: Check for physical damage and test resistance with a multimeter. Replace if open, shorted, or out of expected range.
4. Check wiring to PCB: Trace the harness from the sensor to the main control board, looking for pinched or broken wires.
5. PCB relay check: If the sensor is good, the fast‑freeze relay or control circuit on the PCB may be stuck or failed. Replacement of the PCB is usually required.

Note: A stuck fast‑freeze circuit can cause excessive energy use and overly low temperatures; resolve E11 promptly.
