U-Line Refrigerator Error Code Slow Flash

A Slow Flash on a U-Line CLR2060 refrigerator means the control board has detected a problem with the thermistor circuit. This happens when the thermistor plug is disconnected from the board or when the thermistor itself has failed open. The board can no longer read a valid temperature signal, so it triggers this alert to indicate a sensor fault.

A power reset will not permanently clear the Slow Flash code if the underlying thermistor problem still exists. The control board will detect the open circuit again after power is restored and the error will return. The fault must be corrected at the sensor, connector, or wiring level before the code will clear and stay clear.

If only the thermistor needs to be replaced, parts and labor typically cost in the range of $75 to $200 depending on the service provider and part availability. If the control board is at fault, repair costs can range from $200 to $400 or more. Reconnecting a loose plug, if that is all that is needed, may cost nothing beyond a service call fee.

Start by checking that the thermistor plug is firmly connected to the control board. If the plug is secure, use a multimeter to test the thermistor for resistance. A thermistor reading open circuit means it needs to be replaced. Also inspect the wiring harness between the sensor and the board for any breaks or corrosion.

Continuing to run the refrigerator with an active Slow Flash error is not recommended for food safety. Without a functioning temperature sensor, the control board cannot accurately regulate the cooling cycle, and cabinet temperatures may drift above safe levels. Food spoilage is a real risk until the sensor issue is resolved.
