Why Defrost a Wine Fridge?

When wine coolers and wine cabinets are turned on for the first time, frost or ice buildup (usually in the form of ice crystals) commonly forms on the back wall.

When you first get the unit, the door will most likely be open frequently as you load new bottles of wine, remove packaging, and rearrange your shelving.

The wine cooler’s internal humidity may be influenced by humid air entering from outside the cabinet. Sensors ensure that the wine cooler does not overheat and that the humidity stays between 50 and 80%. If moist, cold air enters the wine cooler during the cooling cycle, it may freeze. When this happens, water molecules may condense and possibly freeze on the back wall.

Why does my wine cooler keep freezing

Wine bottles placed directly beneath cold airflow in a wine cellar will restrict airflow, causing a backup of the cooling unit and ice buildup.

You’ll need to defrost the unit to fix this. The first step is to unplug the wine fridge from the power source and leave it unplugged for at least 8 hours or overnight to allow the ice to melt. Make sure to follow the instructions listed further below.

When should you defrost your wine refrigerator?

If your wine cooler isn’t working properly, it should be defrosted. If the temperature is not as cold as it should be, the cooler may need to be defrosted.

Most of the time, your wine cooler will not need to be manually defrosted, but there may be times when it does. If the temperature is very low and/or the unit is located in a humid area, it is possible that it will freeze. This can happen if warm, humid air enters the unit faster than the cooling system can remove it. Limiting the number of times the door is opened and closed is a good idea.

The steps below will show you how to manually defrost your appliance.

How long does it take to defrost a wine cooler?

This is heavily dependent on the physical size of the wine fridge; large wine fridges will obviously take longer to defrost than small wine fridges. Because size is frequently correlated with bottle capacity, a 300 bottle wine fridge would take much longer to defrost than a 50 bottle wine fridge. Furthermore, the cooling type correlated well with the physical size, with thermoelectric wine coolers being only really suitable for smaller units, as opposed to a compressor wine cooler system.

The defrosting process can also be affected by the location of the wine cooler, as well as the humidity of the room, and so on.

How to Defrost a Wine Fridge?

  1. Empty the wine fridge of all bottles and properly store them.
  2. Unplug the power cord and turn the unit off.
  3. Allow the unit to fully warm inside by opening the door and waiting for it to reach room temperature. Using towels, pans, and basins, collect melted ice and water.
  4. Ascertain that all frost has melted. Depending on the humidity and temperature of the room where the unit is located, the time can range from 24 to 48 hours.
  5. You can clean the inside of the unit with a soft cloth and a mixture of lukewarm water and baking soda (2 tablespoons baking soda in 1 quart of water should suffice).
  6. Then, using a soft cloth, thoroughly dry it.
  7. Before connecting the power, make sure the unit is completely dry.
  8. Turn on the wine storage unit and experiment with different temperature settings.
  9. Allow the unit to cool to the desired temperature.
  10. Replace your wine collection in it.


    After you’ve completed the preceding steps, don’t forget to celebrate with a bottle of cabernet sauvignon, sauvignon blanc, or pinot noir!
