U-Line Refrigerator Error Code R Temp Hi 12H+

This code means the right zone of your U-Line refrigerator has been at least 10 degrees above the set temperature for more than 12 continuous hours. It is a sustained cooling failure alert, not a brief fluctuation. The unit has been unable to maintain proper temperature in the right zone long enough to trigger a timed alarm. Immediate inspection of the door gasket and door alignment is the recommended first step.

A reset may clear the displayed code temporarily, but the error will return if the underlying cause has not been fixed. Because the fault requires 12 or more hours of sustained high temperature to trigger, a reset without a repair only delays the alert while the cooling problem continues. Address the root cause first before relying on a reset.

Repair costs vary depending on the cause. Replacing a door gasket typically falls in the range of $50 to $150 for parts and labor, while a thermistor or evaporator fan motor replacement may run $100 to $300 or more depending on parts availability and local labor rates. If the issue involves the refrigerant system or control board, costs can be higher. A diagnostic service call will help identify the specific failed component before committing to a repair.

Start by inspecting the right zone door and gasket for visible damage, gaps, or misalignment, especially if you also notice frost buildup inside the compartment. If the gasket seals properly and the door closes correctly, check whether the evaporator coil is heavily frosted, as this restricts airflow and cooling. For issues beyond the door seal, a technician may need to test the thermistor, evaporator fan motor, and refrigerant system.

Food safety is a concern with this error, since the right zone has been above the safe temperature range for an extended period. Perishable items like meat, dairy, and prepared foods that have been held above 40 degrees Fahrenheit for more than two hours are generally considered unsafe. Review the contents of the right zone carefully and discard anything that may have been compromised.
