What is a Refrigerator Garage Kit?

A refrigerator garage kit is a simple accessory designed to help a standard refrigerator operate efficiently in the colder temperatures commonly found in garages, ensuring proper function throughout the year.

For many homeowners, the garage is not just a place to park cars; it's also a secondary storage space for overflow items, including an extra refrigerator for drinks, excess groceries, or holiday cooking. However, standard refrigerators often struggle to maintain proper temperatures in the fluctuating conditions of a garage, especially in colder climates. Refrigerator garage kits address this problem by ensuring that these appliances function efficiently year-round, despite the challenging environment.


  • Refrigerator garage kits help maintain safe and consistent temperatures in garage-stored refrigerators, especially in cold climates.
  • Installing a garage kit can enhance the energy efficiency and longevity of your refrigerator by stabilizing its operating conditions.
  • Professional installation of a garage kit is recommended to ensure optimal performance and compliance with safety standards.

How Refrigerator Garage Kits Work

Refrigerator garage kits are accessories that help with the optimal functionality of refrigerators stored in garages, particularly in climates that experience extreme temperatures. These kits modify the refrigerator's built-in thermostat system, which can be fooled by ambient garage temperatures into underperforming. By ensuring that the refrigerator operates its cooling cycle sufficiently, garage kits help keep your stored food at safe temperatures, even when external conditions are less than ideal.

Adapting to Cold

When temperatures drop, a refrigerator's thermostat may interpret the cool environment as a cue to lessen or cease its cooling efforts. This misreading can jeopardize food safety by allowing temperatures inside the fridge to rise above safe levels. A garage kit addresses this issue effectively by:

  • Ensuring continuous operation of the cooling cycle during cold weather.
  • Preventing the thermostat from misinterpreting external cold as an internal cue.
  • Maintaining consistent internal temperatures to keep food fresh.


The primary components of a refrigerator garage kit are a heating coil and a secondary thermostat. Together, these elements deceive the refrigerator's main thermostat into activating the cooling cycle more frequently, thus countering the cold conditions of a garage. This setup includes:

  • A heating coil that attaches near the refrigerator's thermostat.
  • A secondary thermostat that monitors and controls the heating coil's temperature.
  • Necessary wiring and connectors to integrate seamlessly with existing refrigerator systems.

Why You Might Need a Garage Kit

Garage kits are not universal necessities for all refrigerators; however, they become indispensable for units positioned in unconditioned spaces such as garages, particularly in areas with colder climates. These kits play a pivotal role in maintaining the refrigerator's efficiency and effectiveness in adverse environmental conditions.

Temperature Regulation

A primary benefit of installing a garage kit is the assurance of consistent, safe food storage temperatures. Without this adjustment, the refrigerator might not activate its cooling cycle as needed, leading to potential food spoilage or freezer burn. Key advantages of temperature regulation include:

  • Maintaining optimal internal temperatures to prevent food from becoming unsafe.
  • Ensuring that the cooling cycle activates even when external temperatures drop significantly.
  • Reducing the risk of food spoilage and freezer burn, which are common in fluctuating temperatures.

Energy Efficiency

A garage kit enhances the refrigerator's operational efficiency by aligning the cooling cycle more closely with the actual needs of the appliance, despite external temperatures. This can reduce energy consumption by:

  • Minimizing the frequency of unnecessary cooling cycles in cold conditions.
  • Reducing the overall energy required to maintain safe internal temperatures.
  • Ensuring that energy expenditure is optimized, resulting in lower utility bills.


By maintaining more stable internal temperatures, a garage kit indirectly contributes to the longevity of the refrigerator. Consistent temperatures help reduce the stress on mechanical components, leading to:

  • Less frequent cycling of the compressor, which can extend its operational life.
  • Reduced wear and tear on internal components from fluctuating temperatures.
  • Increased overall lifespan of the refrigerator, ensuring better performance over time.

Installing a Refrigerator Garage Kit

Installing a refrigerator garage kit can be a straightforward task for the DIY-savvy homeowner, but it's crucial to understand the process thoroughly. This understanding helps you decide whether to undertake the installation yourself or to enlist the services of a professional.

Compatibility Check

Before beginning the installation process, the first and most crucial step is to verify that the garage kit is compatible with your specific refrigerator model. This step ensures that the kit will function as expected and prevents potential damage to your appliance. Important aspects of the compatibility check include:

  • Checking the refrigerator model against the kit's supported models.
  • Consulting with the manufacturer or a professional to confirm compatibility.
  • Ensuring that all required components are included in the kit.

Installation Process

The installation process for a garage kit typically involves mechanical and electrical work, which might be manageable for those with some technical skills. Key steps include:

  • Positioning the heating coil in proximity to the refrigerator's thermostat to effectively influence its readings.
  • Carefully following the detailed instructions provided by the manufacturer to ensure correct installation.
  • Connecting wires and components securely to avoid any operational issues.

Given the technical aspects of installing a garage kit, hiring a professional may be advisable. A qualified technician can ensure that the kit is installed correctly and functioning as intended, providing peace of mind. Reasons to consider professional installation include:

  • Guaranteeing that the installation complies with safety standards.
  • Avoiding common mistakes that can occur during DIY installations.
  • Ensuring that the warranty of your refrigerator is not voided by improper installation.

Maximizing the Efficiency of Your Garage Refrigerator

To ensure your garage refrigerator operates at peak efficiency, simply installing a garage kit is not enough. Adopting additional practices can improve performance and energy conservation, helping maintain optimal conditions for food preservation throughout the year.

Proper Placement

Correctly positioning your refrigerator within the garage is crucial for minimizing exposure to environmental factors that can strain the appliance's efficiency. Effective placement involves:

  • Locating the refrigerator in a shaded area away from direct sunlight which can increase the internal temperature.
  • Avoiding proximity to heat sources such as machinery or vents that can disrupt its cooling efficiency.
  • Ensuring there is adequate airflow around the appliance to prevent overheating and help maintain consistent internal temperatures.

Regular Maintenance

Routine upkeep is essential to sustain the refrigerator's performance and efficiency. Regular maintenance tasks include:

  • Cleaning the condenser coils periodically to ensure they are free of dust and debris which can impede heat exchange.
  • Checking and maintaining the garage kit components, such as the thermostat and heating coil, to ensure they are functioning properly.
  • Regularly monitoring the internal temperature to verify that it stays within safe food storage limits.


Enhancing the insulation around your garage refrigerator or within the garage itself can reduce the influence of external temperature fluctuations. Strategies for effective insulation include:

  • Installing insulation panels around the refrigerator to stabilize internal temperatures.
  • Considering broader garage insulation projects that help maintain a more consistent ambient temperature.
  • Sealing any gaps or leaks in the garage that may introduce cold drafts or heat influxes.
