Keeping appliances going in a garage can be difficult. Garage temperature can fluctuate drastically, from extreme heat and humidity to extreme cold. In some climates, where winters are longer and more intense than the summer months, the extreme cold may keep your garage refrigerator from running properly. If this happens, your food may freeze and items like bottles of soda may explode and cause a big mess. Luckily, you can take steps to keep your refrigerator going in the garage during colder times of the year.
Monitor the temperature of your garage for several days before you put food in the refrigerator. Different garages have different levels of insulation, and you'll need to know how your garage responds to the cold, since many refrigerators will only work properly if the garage temperature doesn't drop below 12.8 degrees Celsius. If it does drop below 12.8 degrees Celsius, you may have a problem keeping your refrigerator functioning properly unless additional steps are taken. Determine the temperature outside when the garage dips below 12.8 degrees C so that you're aware of the difference between the temperature inside and outside the garage.
Place a small space heater near the refrigerator when the temperature drops below 12.8 degrees Celsius. Don't worry about the garage getting too hot. Your refrigerator will function as long as the temperature doesn't near 37.8 degrees Celsius. Understand that this isn't a long term solution and should only be used occasionally.
Purchase a refrigerator that is designed for cold environments. These types of refrigerators can be purchased at retail stores and online stores. They are designed to keep the inside of the refrigerator a consistent temperature, regardless of how cold the environment gets. This is the best solution if your garage frequently drops below 12.8 degrees Celsius.
