U-Line Ice Maker Error Code Bin T Open

Bin T Open means the control board has detected an open circuit in the bin thermistor circuit. The bin thermistor is the temperature sensor that monitors conditions inside the ice storage bin. When the board receives no valid resistance signal from that sensor, it triggers this fault and halts normal operation. The cause is most often a corroded connector, a loose harness, or a failed thermistor.

A reset may temporarily clear the displayed code, but the fault will return immediately if the underlying problem has not been corrected. The control board continuously monitors the thermistor circuit, so any open circuit condition will trigger the error again on the next diagnostic cycle. The physical cause must be repaired before the unit will operate normally.

If the fix is simply cleaning or reseating a corroded connector, there is no parts cost involved. If the thermistor needs replacement, the part itself typically costs in the range of $20 to $60 depending on the specific model. Adding professional labor, a service call to diagnose and repair this fault generally runs between $100 and $200 in total depending on your location and the technician's rates.

In many cases, yes. Start by unplugging the unit and inspecting the thermistor connector and the harness connector at the main board for moisture, corrosion, or loose fit. Cleaning corroded terminals or reseating a loose connector often resolves the fault. If connections are in good condition, the thermistor itself will need to be replaced, which is a straightforward part swap for a handy homeowner or technician.

It is not recommended to operate the unit with an active thermistor fault. Without a functioning bin temperature sensor, the control board cannot accurately monitor conditions in the ice bin, which can lead to improper ice production cycles or potential component stress. Diagnose and resolve the fault before returning the unit to regular use.
