Possible Causes
Out-of-range NTC sensor values, Incorrect sensor type fitted previously, Firmware calibration error, Wiring cross-connection between sensors
How to Fix / Troubleshooting
Safety: Disconnect power before testing sensors or wiring.
E18 is a temperature reading/calibration error.
- Verify sensors: Check that the correct Candy NTC sensors are installed in fridge, freezer, and evaporator positions. Mismatched sensors can cause range errors.
- Measure resistances: At a known temperature (e.g., 20°C), measure each sensor and compare values. Replace any that are significantly out of expected range.
- Check wiring: Ensure sensor harnesses are not swapped between connectors on the PCB.
- Control reset: After corrections, unplug for 10 minutes, then reconnect to allow the PCB to reinitialize.
- PCB replacement: If all sensors and wiring are correct, the control board calibration may be corrupted and require replacement.
