    Why Is There Ice Build Up In My Wine Fridge? (How To Fix)

    Why Is There Ice Build Up In My Wine Cooler

    Ice build up in a wine fridge is a common problem. Ice can form in wine coolers when moist air enters the appliance in the cooling cycle. Moisture can enter the wine fridge, condense and cause the back wall of the fridge to freeze causing an ice build up. 

    In the worst case scenario, if the ice in the wine fridge if left for a long time this can cause your wine to freeze along with the freezing bottles!

    Why Does My Wine Fridge Keep Icing Up? 

    Most of the time any ice forming will melt away when the temperature inside the wine cooler is stable and the cooling system switches off.

    Listen to this post here:

    Then the ice will gradually melt and in the majority of wine fridges an in built tray will safely capture any water which will slowing evaporate once the humidity in the wine cooler is at 50-80%.

    Using a wine fridge allows your wine collection to benefit from stable conditions with accurate temperature, no vibration and they are odourless inside due to charcoal filters used. But ice build up at the rear of a wine cabinet can cause appliance to stop working.

    Here are 3 reasons why you have ice build up in your wine fridge or beverage cooler...

    Ice In a Wine Fridge

    1. Faulty Wine Fridge Door Seal

    Faulty seals on the door of your wine fridge could be letting moist air into the interior of your wine fridge. This moist air can build up and condense on the back of the wine cabinet. Couple this moist air with the controlled temperatures found within wine fridges and you have the recipe for ice to begin to form.  

    Naturally, a faulty door seal can contribute to the amount of moist air entering your wine fridge but is not the only reason why the door might not be closing properly. 

    2. Exceeding Maximum Capacity  

    Ensure that you store the correct amount of wine bottles in your cooler to make sure that the door can close properly.  

    If you find you have excess wine and nowhere to store it, consider investing in aageing wine cabinet that can hold a more significant number of bottles or storing them in a wine cooler than is in your garage or basement.  

    3. Opening And Closing The Wine Fridge Door

    Opening and closing the wine cooler door can contribute to a build up of ice. Just like a faulty door seal mentioned previously, opening the wine fridge door for long periods of time allows excess moist air to enter the wine cooler. When 

    Minimising the amount that you open and close the door will reduce the chance of ice build up. When you first install a wine fridge you will likely open and close the door frequently whilst loading wine bottles into the fridge. 

    This allow moist air from outside the cooler to become trapped inside the appliance when the door is closed - raising the humidity inside the appliance.

    Do Wine Coolers Need Defrosting?

    If your wine / beverage cooler is operating correctly you will not need to manually defrost the appliance as your wine cooler won't freeze in the first place. 

    If ice builds up in the appliance and doesn't disappear in 24-48 hours it's likely there is a problem with excess moisture entering the unit.

    How Do You Get Ice Out Of A Wine Fridge? (Defrost)

    If you need to remove ice from your wine cooler (defrost it essentially) it's important to minimise the risk of permanent damage to the appliance due to water ingress in the electrical components.

    • First you should empty the fridge
    • Then switch off the power
    • And finally start removing the ice, frost and water with a towel
