A typical, standard refrigerator is not designed to work in a garage or outside the area that isn’t environmentally controlled for a garage you need the best garage refrigerator or need to install garage refrigerator kit in your standard refrigerator.  Following these instructions on how to install a garage refrigerator kit to a standard model refrigerator will ensure that you can undertake this easy job yourself, at your refrigerator works

How your refrigerator works:

Your refrigerator monitors the outside temperature and uses that guide to control the freezer temperature.  The excess air from the freezer is then blown into the fridge area to maintain your food at the correct temperature.

Usually, there is also a thermostat in the refrigerator section which monitors the temperature – and the evaporator is located in the freezer section.  That leaves both sections of the unit operating slightly independently of each other, but both dependent upon the outside temperature wherever the unit is placed.

In a temperature controlled indoor area which is maintained at a more or less consistent temperature, this works very well.  If you take that model refrigerator into an uncontrolled environment, then for any standard model without a garage refrigerator kit fitted, you face problems – not to mention excessive electricity bills.

In winter then your refrigerator will think that it is cold enough, if it’s below freezing in your outhouse then the refrigerator will not work at all, and all of your freezer contents will thaw, not good for anybody.

In Summer, if your location gets hot, then the refrigerator will be working constantly in order to reduce the internal temperature appropriately.

What a Garage Refrigerator Kit Does

A garage refrigerator kit is a very small, easily installed heating coil which you fit around the thermostat.  This warms the air and so the refrigerator does not respond to the air temperature of the garage.  It means that in the cooler months your refrigerator will continue to run, and your food will remain safe.
