How to Turn Your Mini Fridge Into a Wine Refrigerator

Last Updated: July 12, 2022

Wine refrigerators can be very expensive, with even the cheapest models running about two hundred dollars. So why buy one when you can convert your mini-fridge into a fully functioning wine refrigerator in just a few simple steps?

Method 1

Method 1 of 2:

Timer Method

1
Buy an appliance timer and thermometer. You can find an appliance timer in most hardware stores in the lighting section. Refrigerator thermometers are pretty easy to find. You can get them at pretty much any grocery store.
2
Set up the timer. Plug your mini-fridges power cord into the appliance timer. Then plug the appliance timer into the outlet.

3
Turn the power setting to the lowest possible and put the thermometer in the mini-fridge. Allow it to run, and take the temperature. Once it is below 55 degrees F (proper wine storage temp) then move on to the next step.
4
Set the appliance timer to raise the mini-fridge temperature to 55 degrees F (12.8 degrees C). Basically, the appliance timer can be set to intervals that will turn on and off power to the mini-fridge. This will effectively raise the temperature enough to make it a good place to store wine. Start with 2 hours on, 2 hours off intervals. If you start with this, and the temperature ends up above 56 degrees F, adjust the timer so that it has longer settings, like 2 1/2 hours on, 1 and 1/2 hours off. Likewise, if the temperature reads too low, adjust your timer so that it has longer off settings, 1 1/2 hours on and 2 1/2 hours off.

Thermostat Tinkering Method

1
Pull the control knob straight off the thermostat. You'll probably see a small screw next to the main control. That's the calibration screw.
2
Twist the calibration screw. Twisting it counterclockwise is likely to alter the temperature range so that the fridge doesn't get as cold, but the only way to make sure is to find out which direction turns the compressor on, then twist it in the opposite direction slightly past its original position.
3
Wait 12 to 24 hours, then take the temperature. Make incremental adjustments to the calibration screw until you get a good temperature for wine.

Question

What the temperature of a mini fridge be?

Community Answer

Keep the refrigerator temperature at or below 40° F (4° C). The freezer temperature should be 0° F (-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these temperatures and are generally inexpensive.

Warnings

It's recommended that you do this with a refrigerator that you don't depend on for any other purpose (food, beer, medication).

Wines that are stored for long periods of time in this type of wine fridge may be damaged by the vibrations from the compressor. (This is why wine fridges are more expensive - they isolate the vibrations from the compressor so the wine is not affected. However, for short-term storage, the effects should be negligible.)
