CellarPro Runs Constantly



The cooling capacity of the cooling unit depends on the thermal load on the wine cellar, and the resulting BTU that is required to cool and maintain the cellar at the desired temperature. Our cooling capacities were calculated based on the following assumptions: R-11 Insulation and 85 degrees ambient temperature. If the ambient temperature outside your cellar is higher than 85 degrees, you will need more insulation and/or the cooling capacity of the cooling unit will decline.

CellarPro wine cooling units are designed to turn on when the air temperature in the cellar rises above the Minimum Set Point + Temperature Differential, and turn off when the air temperature falls below the Minimum Set Point. For example, if the Minimum Set Point is 58°F and the Temperature Differential is 4°F, the cooling unit will turn above 62°F and turn off below 58°F. 

When bottles are first loaded in the cellar, the cooling unit will run continuously (even up to a week) until the temperature inside the cellar falls below the Set Point. The cooling unit will cool a maximum of 30°F below the ambient temperature in the space outside the condenser coils. For example, when the ambient temperature in the space outside the condenser coils is 90°F, the cooling unit can't cool below 60°F inside the cellar.

Hot weather conditions, insufficient insulation, inadequate ventilation, missized cellar capacity and/or dirty condenser coils can all cause the cooling unit to run continuously.

If your CellarPro wine cooling unit runs constantly, try the following:

  • Clean the condenser coils
  • Check the ambient temperature in the space outside the condenser coils while the cooling unit is running, making sure that the difference between this temperature and the Minimum Set Point is no more than 30°F.
  • Increase the supply of cool air to the space outside the condenser coils, using a fan, ducting or an exhaust system to remove heat from the space.
  • Make sure that the cooling unit is NOT in Energy-Saver Mode
  • Raise the Minimum Set Point on the cooling unit
