U-Line Ice Maker Error Code Bin T Short

The "Bin T Short" error code on a U-Line ice maker indicates that the bin thermistor circuit has developed a short condition. The bin thermistor is a temperature-sensing resistor responsible for monitoring the ice bin temperature and signaling the control board when the bin is full or when temperatures fall outside acceptable operating ranges. A shorted thermistor circuit means the resistance value the main board is reading has dropped below the expected range, which the board interprets as a fault rather than a valid temperature reading.

Thermistor shorts typically occur at one of two locations: the connector where the thermistor wiring attaches to the wiring harness, or the connector where the harness plugs into the main control board. Moisture intrusion is a very common culprit in ice maker environments, since condensation and ice melt can migrate along wiring and pool at connector points. Corrosion builds up at these connection points over time, eventually creating a low-resistance path that the board reads as a short. In some cases, the thermistor component itself has failed internally and is producing an out-of-range resistance reading regardless of connection quality.

Diagnosing this code begins with a thorough inspection of both connector points for signs of moisture, corrosion, or physical damage. If the connectors appear clean and are making solid contact, the thermistor itself should be tested for correct resistance output and replaced if it is reading outside specification. Clearing the fault without addressing the root cause will result in the code returning immediately.
