E05 error, unit runs briefly then shuts down; cabinet temperature reading is incorrect or unstable.

Safety first: Unplug the ice maker before removing any covers.

• Locate cabinet sensor: The Balay cabinet or ambient NTC is usually mounted on the interior liner or near the air return grill. Remove the inner panel if necessary.
• Visual inspection: Check that the sensor bulb is intact and not covered in heavy ice or moisture. Inspect the wiring for damage.
• Connector check: Reseat the sensor connector at both ends. Clean any oxidation with contact cleaner and allow to dry.
• Measure resistance: At room temperature, measure the NTC resistance and compare to Balay's chart. Replace the sensor if readings are out of range or intermittent when the wire is gently flexed.
• Control board evaluation: If the sensor tests good but E05 persists, the main control PCB may misread the sensor and should be replaced.
