U-Line Ice Maker Bin T Open: Storage Bin Sensor Circuit Open
Bin T Open means a break in the bin thermistor circuit, so your U-Line ice maker has no storage bin reading. A loose connector, failed sensor or wiring damage may be the cause.
What does U-Line ice machine code Bin T Open mean?
Bin T Open tells you the bin thermistor circuit on your U-Line ice maker is open, so no storage-bin temperature reaches the board. The bin is where finished ice is held, and its sensor helps the unit know how the stored ice is doing. A loose or damaged connector, a worn-out sensor, or wiring damage are the causes tied to this code. The message identifies the bin sensor and the open condition, but not the exact point of the break.

How the ice machine detects Bin T Open
Ice that has been made has to be stored somewhere, and in your U-Line unit that place is the bin. A thermistor in the bin area lets the control read how warm or cold the stored ice is. The sensor's resistance changes with temperature, and the board treats that number as one input among several when deciding how to run.
When the electrical path through the sensor is broken, the board receives nothing it can turn into a temperature. It reads that as an open circuit and shows Bin T Open. Without the bin reading, the control cannot be sure the stored ice is being held properly, so it may limit its behavior until the connection or sensor is restored.
Likely causes of Bin T Open
- A loose or damaged connector at the bin thermistor
- A bin thermistor that has stopped working
- Damage to wiring that runs to the bin sensor
Can you keep using the ice machine with Bin T Open?
You can keep the unit running while you wait, but check the stored ice with your own eyes. If the ice looks wet, slushy or has melted and refrozen into lumps, do not serve it. If you see water pooling or smell anything hot, switch off the breaker.
What you can safely check
- Stop the ice maker, unplug it or switch off its breaker, and stop the water at its shutoff if you can get to it.
- Wait about a minute and restore power.
- Open the door and look at the ice in the bin, noting whether it is clumped, melted or very low, without reaching near the sensor.
- Watch whether Bin T Open returns.
- If it does, call us and describe the state of the ice.
What our technician does for Bin T Open
- Check the bin thermistor connector for a loose or damaged fit
- Test the bin sensor to see if it has failed
- Inspect the wiring leading to the bin for breaks
How to keep Bin T Open from coming back
- Keep the door closed and sealed so the bin stays cold
- Do not store anything in the bin that could press on the sensor wiring
- Use a surge protector so storms do not damage the sensor circuits
- Scoop ice with a clean scoop instead of reaching around the sensor area

Bin T Open questions
What does the bin sensor do?
It reports the temperature in the compartment where finished ice is stored. The control uses that reading to understand the state of the bin, and an open circuit cuts it off.
Will the bin keep my ice frozen?
The sensor reading and the cooling are separate matters. The ice may stay solid for a while, but with the reading gone the unit cannot manage the bin properly, so check the ice yourself.
Is Bin T Open the same as Zone T Open?
No. They share the type of problem but concern different sensors. Each message names the sensor it applies to, and the repair goes to that sensor's connector and wiring.
Could leaving the door open cause Bin T Open?
Warm air in the bin changes the temperature but does not break the sensor circuit. An open circuit comes from a connector, wire or sensor. Still, a door that does not seal is worth fixing for the ice alone.
Is the ice safe to use?
We cannot judge that by looking. If the ice has stayed hard and clean, many people keep using it, but if it has melted or tastes off, throw it out and start a fresh batch after repair.
