Shop fridge. Beer fridge. Snack fridge. Whatever you call it, a refrigerator in the garage provides extra space and convenience. But most garages aren’t climate controlled, meaning sweltering summers pose a few problems for ideal operations. High temperatures add stress to the machine by forcing the motor to run constantly, especially if your garage exceeds 110 degrees. At best, energy bills will spike. At worst, the motor could burn out from overuse, leading to food spoilage.
Keep It Full
In a hot garage, the refrigerator will battle against the ambient temperature to keep your goodies cold. Help it out by keeping it well stocked. If you don’t need the whole refrigerator, consider filling space with gallons of water. They will remain cool and help the refrigerator maintain its temperature when the door is opened on a hot day. In an empty refrigerator, warm air rushes in and cold air rushes out every time the door opens. Water -- or anything else you keep in the fridge -- will leave less room for warm air, allowing the inside air to return to appropriate temperatures far faster when the door is closed.
Take Charge
Kitchens specifically wired for refrigerators are guaranteed to have proper hookups. Garages are not. Ensure the refrigerator is equipped with a 115 volt, 60 Hz, AC-only electric outlet. Without the correct type of electrical hookup, the refrigerator will not receive enough power. It might not be able to run its motor properly, leading to further strain on the condenser and inability to produce enough cold air. If you don't have the proper hookup or if you are unsure, consult an electrician to set up the proper wiring.
Cool It
GE recommends refrigerators be placed only in rooms where the temperature range stays between 60 and 110 degrees Fahrenheit. In warmer conditions, the refrigerator will not stop running and risks burning out because of overuse. If your garage regularly exceeds 110 degrees, it's not the ideal location for a refrigerator. If you want to place a refrigerator in a very warm garage, consider ways to keep the temperature down. Insulation, supplemental air conditioning, fans and vents will help with cooling. Check all doors and windows for leaks and add weather stripping if necessary to keep heat out as much as possible. Cover windows to minimize heat from the sun. Remove or unplug any additional appliances not in use.
Be Careful What You Store
Even if you follow the proper precautions, placing a refrigerator in a room with extreme temperatures carries increased risk of operational failure. Thus garage refrigerators work well for storing extra beverages, pantry goods or other things that won’t perish if the machine can't handle the heat. Avoid storing highly perishable items during warmer months.
Warning
Some manufacturer warranties could be voided if the machine is placed in a garage at risk for extreme temperatures. Proving whether the temperature has remained in the acceptable range for repair claims is difficult, so if warranty coverage is a concern, ensure your machine doesn't have such a clause. Follow all manufacturer specifications for installation and clearance around the appliance.
