Display shows E04; ice maker may overcool or fail to maintain proper bin temperature.

Safety first: Unplug the unit before removing interior panels.

Steps:

• 1. Locate bin sensor: The bin or storage temperature sensor is usually mounted on the side wall or ceiling of the ice storage compartment. Look for a small plastic-covered probe.
• 2. Visual inspection: Check for physical damage, moisture intrusion, or broken wires at the sensor head.
• 3. Resistance test: Disconnect the sensor and measure resistance at room temperature. Compare to the Blomberg NTC chart. Replace if open, shorted, or far out of spec.
• 4. Harness and connector: Follow the cable to the main PCB, ensuring it is not pinched or cut. Reseat the connector on the board.
• 5. Replace sensor: Install a new bin temperature sensor if defective, ensuring good contact with the mounting surface and proper routing of the cable.
