Should You Unplug a Garage Fridge in Winter? Pros and Cons Explained
Unplugging your garage refrigerator during the winter months can be a wise move to protect the appliance and save on energy costs.
Last winter, the refrigerator in my garage faced the brunt of the season’s chill, prompting me to disconnect it to prevent the unit from straining itself to maintain unnecessary temperatures when not in use.

The appliance relies on ambient temperature for its thermostat to function properly. Too cold an environment can cause the unit to shut off, as it mistakenly believes it’s already cool enough inside. This could lead to frozen pipes or a burned-out compressor when the weather warms up again.
Consider the contents of your fridge before making a decision.
If it’s stocked with perishable items, you’ll want to make sure the inside temperature isn’t subject to the external cold, which could lead the contents to freeze, spoiling your food.
However, if it’s empty or contains only items that won’t spoil in cooler temperatures, unplugging could extend the life of your fridge and reduce your energy bill.
Keep a thermometer inside to monitor the temperature if you decide to keep it plugged in, ensuring the internal environment remains consistent for food safety.
The Case for Unplugging
When winter rolls around, unplugging your garage fridge can be a savvy move for both your wallet and the appliance’s well-being.
Potential Energy Savings
Your garage refrigerator works overtime in the winter, striving to keep the interior warm enough for the thermostat to function properly. This contradictory action can lead to:
- Increased energy consumption: Extra effort means more electricity used.
- Higher energy costs: Higher energy use translates to a heftier electricity bill at the end of the month.

To drive home the point, here’s a quick glimpse at potential energy savings:
Temperature Range | Energy Use | Potential Savings |
---|---|---|
Moderate | Standard consumption | Minimal savings |
Very Cold | Increased consumption | Significant savings |
By pulling the plug, you’re poised to trim down on those energy costs and save some energy, contributing positively to your carbon footprint.
Preventing Mechanical Issues
Unplugging can prevent a slew of mechanical issues that are just waiting to happen in extreme cold:
- Compressor stress: The heart of your fridge, the compressor, may malfunction due to continuous operation in low temperatures.
- Coiled conundrums: The coils can succumb to the wear and tear of temperature fluctuations, potentially leading to rust and other malfunctions.
By choosing to unplug, you’re giving these critical components a well-deserved break, reducing the risk of untimely breakdowns and the associated repair costs.
Extending Appliance Lifespan
Maintenance and optimal performance are cornerstones of a long-lasting appliance. In a freezing garage, several factors can shorten your fridge’s lifespan:
- Freezer burnout: With a heater or temperature kit, you’re forcing the freezer to work against its natural design.
- Wear and Tear: Fluctuations in the temperature lead to continuous cycles of contraction and expansion, which can ultimately decrease the fridge’s efficiency and longevity.
The Case Against Unplugging
When deciding whether to keep your garage fridge plugged in during winter, consider how unplugging could affect your food preservation and daily convenience.

Food Preservation Concerns
Unplugging your garage fridge in colder months may seem thrifty, but it can lead to complications with food safety.
Perishable items like meat, dairy, and certain vegetables need a stable temperature to prevent food spoilage.
Even in winter, indoor garages can fluctuate in temperature, and without a functioning fridge, these perishables could enter the danger zone (above 40°F and below 140°F), where bacteria multiply rapidly. Here’s a brief table of temperature settings necessary for different food types:
Food Type | Refrigerator Temperature |
---|---|
Meat & Poultry | 32°F – 36°F |
Dairy Products | 34°F – 38°F |
Vegetables | 35°F – 40°F |
General Storage | 32°F – 40°F |
Maintaining these temperatures is crucial for food safety.
Convenience Factors
Your primary fridge is likely tailored for everyday use, but your garage fridge might hold overflow from shopping sprees or bulk preparations.
Unplugging it could leave you with a lack of storage space, leading to a cramped kitchen. Plus, the sheer convenience of having additional cold storage for beverages or marinating meats while prepping for a big meal can’t be overstated—think of it as your culinary wingman.
The Risk of Mold and Odors
Ambient humidity in your garage and the lingering moisture inside an unplugged fridge can create an ideal environment for mold and mildew.
If you do choose to unplug, you should ensure that the appliance is clean and dry. Even so, you might need to contend with odors that can develop from mold growth. Deploying a dehumidifier near your unplugged fridge can reduce this risk, but that’s another appliance to manage.
Troubleshooting Common Winter Fridge Issues
Keeping your garage fridge running efficiently during the winter requires attention to specific challenges posed by cold weather.

Maintaining Optimal Temperature
Your garage fridge needs to maintain a consistent temperature to keep food safe.
Most refrigerators are designed to operate in temperatures above 50°F. If your garage drops below this, consider a garage ready refrigerator which is designed to handle colder temperatures. You can also add an insulation blanket to standard units for better efficiency.
- Checklist for Temperature Maintenance:
- Verify your fridge has proper air circulation to avoid hot spots.
- Adjust the thermostat to compensate for the cooler environment.
- For models with two thermostats, ensure both are set correctly to maintain a consistent internal temperature.
Dealing with Freezing Temperatures
When the thermostat reads freezing temperatures, components and stored items are at risk.
If you’re facing temperatures that plummet below the unit’s safe operating range, consider adding a heating element or a heated insulated box around the fridge to prevent freezing issues.
- Action Steps in Freezing Conditions:
- Install a fridge-heating kit or use a small space heater to keep temperatures stable.
- Check for insulation flaws in your garage that may be fixed to create an enclosed, insulated space.
Preparing the Fridge for Unplug
In some cases, unplugging your fridge for the season might be the most energy-efficient move.
If your winter temperature frequently falls below 35°F, defrosting your unit and storing only non-perishable items could save on utility bills and prevent fridge damage.
- Quick Guide to Unplugging the Fridge:
- Clean the fridge thoroughly to prevent mold and smells.
- Leave the doors open slightly after unplugging to ensure air circulation and prevent odor buildup.
- Block any direct pathways to cold air to protect against freezing while it’s off.
Expert Opinions
Deciding whether to unplug your garage fridge in the winter involves consideration from several angles. Expert advice can help point you in the right direction.
Manufacturers: Some fridge manufacturers offer models with dual thermostats, specifically designed to handle external temperature fluctuations. These “garage-ready” refrigerators typically tolerate colder environments without the same risks ordinary fridges might face.
Appliance Experts: Professionals in appliance maintenance suggest that standard fridges may not operate effectively in extremely cold temperatures. The thermostat controls the compressor, so if your garage drops below the fridge thermostat’s lowest setting, it won’t trigger the compressor to maintain the appliance’s internal temperature.
Consideration | Expert Advice |
---|---|
Safety | Unplugging may prevent potential malfunctions due to freezing of internal parts. |
Energy Savings | An unused fridge in a cold garage may increase energy consumption unnecessarily. |
Experts also detail that malfunctions due to cold can include frozen water lines or compromised insulation and sealants. To sidestep these issues, unplugging the unit may be better if your garage temperature dips below 50 degrees Fahrenheit.
Your aim is to balance safety and efficiency. If your garage isn’t suitable for a regular fridge but you need that extra storage, look into a garage-ready refrigerator.
They’re built with these temperature variances in mind, promising both safe operation and peace of mind. If you’re dealing with an ordinary fridge, monitoring your garage’s temperature is key to deciding when to pull the plug.
