U-Line Ice Maker Error Code Condenser T Open

Condenser T Open means the control board has detected an open circuit in the evaporator thermistor circuit located at the condenser line outlet. This sensor monitors refrigerant temperature, and an open circuit means the board is receiving no valid signal from it. The cause is typically a corroded connector, a loose harness connection, or a failed thermistor. The ice maker will not run normally until the fault is corrected.

The error is not a safety hazard to people, but it does prevent the ice maker from operating correctly. Running the unit with an unmonitored refrigerant circuit could contribute to component wear over time. It is best to diagnose and correct the fault promptly rather than leaving the unit in a faulted state.

If the fix is simply cleaning or reseating a corroded connector, the repair may cost nothing beyond your time. Thermistor replacement parts typically range from around $20 to $60 depending on the specific model. If the main control board is the cause, board replacement costs can range from $150 to $350 or more for parts alone, plus labor if a technician is involved.

Yes, in many cases. Start by unplugging the unit and inspecting the thermistor connector and the harness connection at the main board for corrosion, moisture, or loose pins. Cleaning the connector or reseating the harness may resolve the fault without any parts. If connections are good, replacing the thermistor is a straightforward repair that a knowledgeable DIYer can typically handle.

A reset may temporarily clear the fault code, but the error will return if the underlying problem is not fixed. Because the fault is triggered by a physical condition, either a bad connection or a failed thermistor, the control board will detect it again once the unit restarts. Address the wiring connections or replace the thermistor before relying on a reset.
