How do I winterize my refrigerator or ice maker?


Before the weather gets cold, your ice maker and refrigerator should be prepared to handle the weather change. Failure to winterize will not immediately cause unit failure but may reduce the life expectancy of the internal components leading to a premature failure of the unit.

Please Note:  Operation of any appliance outside of its stated safe operating zone can lead to reduce performance or product failure.  Please refer to the operating temperature ranges found in your user manual or product specification documentation. For more information, please refer to the following article: Does the temperature of a room affect my refrigerator's ability to properly cool?

Winterization Procedure

In an ideal situation, the unit can be removed from its outdoor environment and stored in safe, climate controlled environment during the cold weather months.  Naturally, this is not always possible or reasonable and as such, the following steps may be taken to ensure proper maintenance of your unit.  


Power Off Unit

  • Ensure that the unit is turned off and unplugged. 
  • Ideally, turn off the power to the outlet if the circuit is not required during the winter season.  

Turn off Water / Drain Lines

  • For ice makers, shut off the water supply and drain the water lines.
  • For kegerators, drain beer lines completely.

Clean Exterior

  • Take off the front grill and use a vacuum cleaner to clean the area behind it. Use a soft bristle brush only being careful not to damage any components.  Reattach the grill when done.
  • Use a vacuum cleaner to clean the rear of the unit and compressor compartment.  Use a soft bristle brush only being careful not to damage any components.  
  • Wipe down all interior surfaces with antibacterial cleaner and follow with a clean rinse of water to remove any residual chemicals that could result in staining. Note: Do not use any abrasive cleaners or scouring pads.

Clean Interior


  • It is recommended that any glass shelving be cleaned, removed and stored inside your home.
  • For ice makers, empty the storage bin, clean it, and make sure the drain valve is closed.
  • For kegerators, remove CO2 tank and keg(s)
  • Completely empty the refrigerator and gently clean it with soap and water.
  • Ensure the interior of the unit is completely dry and free from moisture.

Final Preparation

  • Place an open box of baking soda in the refrigerator reduce the buildup of odors.
  • It is not recommended that you cover your ice maker or refrigerator. This can lead to an accumulation of moisture that can damage the unit.  

Periodic Check

  • Every 2-3 weeks, open the door to your appliance and check for moisture or ice buildup, moisture or mold growth.
  • Clean as needed.
  • Opening the units door will help reseal the door gasket to the unit in case freezing temps has reduce the effectiveness of the seal.  This will also provide fresh air to enter the unit reducing any possible odor buildup.
