U-Line Ice Maker Error Code R Temp Hi 6H+

R Temp Hi 6H+ means the right zone of your U-Line ice maker has been measuring more than 10 degrees above its set point temperature for over six hours continuously. The unit detected a sustained inability to cool the right compartment to the target level. This is a protective alert designed to notify you of a cooling failure that has persisted long enough to affect ice production and food safety.

A power reset may temporarily clear the displayed error, but the code will return if the underlying cause has not been addressed. Because the fault requires six or more hours of elevated temperature to trigger, simply resetting the unit without correcting the root problem will result in the error reappearing. Always resolve the cause of the temperature rise before relying on a reset to confirm the repair.

Repair costs vary widely depending on the cause. Replacing a door gasket is generally the least expensive fix, typically ranging from around $30 to $100 for parts plus labor. Thermistor or fan motor replacements can range from $75 to $250 including parts and labor. If the issue involves the refrigerant circuit or compressor, costs can range from $200 to $600 or more depending on the extent of the repair and local labor rates.

Start by inspecting the door and door gasket for proper alignment and a tight seal, as air infiltration is the most common cause of this fault. If you notice heavy frost buildup inside the unit, allow it to defrost fully and check whether the error returns. If the door and gasket are in good condition, the next steps include cleaning the condenser coils, checking fan motors for operation, and testing the right zone thermistor. Persistent faults after these checks may indicate a refrigerant or compressor issue requiring a certified technician.

Yes, sustained elevated temperatures in the right zone can compromise the quality and safety of stored ice and any perishable items kept in that compartment. A temperature that is more than 10 degrees above the set point for over six hours indicates the zone is not being adequately refrigerated. You should address the fault promptly and discard any ice or food that may have been exposed to unsafe temperatures during the event.
