A refrigerator is a staple appliance in nearly every household. When it’s humming away, keeping our food fresh, we barely give it a second thought. But what happens when life throws you a curveball? Maybe you’re moving, renovating, or dealing with a second fridge you no longer need. The question arises: how long can a refrigerator sit unused without causing damage or creating a health hazard? The answer isn’t as straightforward as you might think.
Understanding the Risks of Leaving a Refrigerator Unused
Leaving a refrigerator dormant for an extended period presents a few potential problems. These issues range from unpleasant odors to actual damage to the appliance itself and even health risks associated with mold and mildew growth.
Mold and Mildew: The Unseen Threat
The primary concern with an unused refrigerator is the growth of mold and mildew. These fungi thrive in dark, damp environments, and a closed refrigerator is the perfect breeding ground, even if you think you’ve cleaned it thoroughly.
Moisture, even trace amounts left from condensation or residual food particles, can fuel mold and mildew growth. These organisms can produce unpleasant odors that are difficult to eliminate and, in some cases, can trigger allergic reactions or respiratory problems.
Furthermore, some types of mold produce mycotoxins, which are toxic substances that can pose a serious health risk. While not all molds are dangerous, it’s best to prevent their growth altogether.
Odor Buildup: A Stale Situation
Even if mold doesn’t take hold, an unused refrigerator can develop a stale, unpleasant odor. This is due to the breakdown of residual food particles and the accumulation of stagnant air. Once this odor sets in, it can be incredibly difficult to remove, even with thorough cleaning.
The materials used in the refrigerator’s construction, such as plastic and rubber, can absorb these odors, making them persistent.
Mechanical Issues: Potential Damage
While less immediate than mold or odors, leaving a refrigerator unused can potentially lead to mechanical issues down the line. The refrigerant, for example, may settle, and the compressor might experience problems when you try to restart the appliance after a long period of inactivity.
Gaskets and seals can dry out and crack, reducing their effectiveness when the refrigerator is put back into service. This can lead to energy inefficiency and temperature control problems.
Preparing Your Refrigerator for Storage: A Step-by-Step Guide
Proper preparation is crucial to minimizing the risks associated with leaving a refrigerator unused. Taking the time to follow these steps will significantly increase the chances of the refrigerator remaining in good condition during storage and being easily revived when you need it again.
Step 1: Emptying the Refrigerator Completely
This may seem obvious, but it’s the most critical step. Ensure that all food items, including condiments, drinks, and ice, are removed from the refrigerator and freezer compartments. Even seemingly harmless items can decompose and cause significant problems.
Check every shelf, drawer, and door compartment to ensure nothing is left behind. Dispose of any expired or spoiled items properly.
Step 2: Thorough Cleaning Inside and Out
Once empty, give the refrigerator a thorough cleaning. Use warm water and a mild detergent to wipe down all interior surfaces, including shelves, drawers, walls, and door seals. Pay particular attention to any spills or food residue.
For stubborn stains or odors, you can use a solution of baking soda and water. Baking soda is a natural deodorizer and can help to absorb unpleasant smells.
Don’t forget to clean the exterior of the refrigerator as well. Wipe down the doors, sides, and top to remove any dust or dirt.
Step 3: Defrosting the Freezer Compartment
If your refrigerator has a freezer compartment, it’s essential to defrost it completely before storing the appliance. Allowing ice to melt naturally can take time, but it’s the most effective method. You can speed up the process by placing bowls of hot water inside the freezer.
Once the ice has melted, wipe down the freezer compartment thoroughly to remove any remaining moisture.
Step 4: Drying Everything Completely
This is a critical step often overlooked. Mold and mildew thrive in damp environments, so it’s essential to ensure that the refrigerator is completely dry before storing it.
Use clean towels to dry all interior surfaces, paying particular attention to corners and crevices. Leave the doors open for several hours, or even a day, to allow air to circulate and dry any remaining moisture. You can also use a fan to speed up the drying process.
Step 5: Addressing Odor Control
Even after cleaning, some residual odors may remain. To combat this, place an open box of baking soda inside the refrigerator. Baking soda is an excellent odor absorber and will help to keep the appliance smelling fresh.

Activated charcoal is another excellent choice, known for its high absorption capacity. You can find activated charcoal in various forms, such as granules or filters.
Another surprisingly effective odor absorber is coffee grounds. Dried, unused coffee grounds work best, as they won’t introduce any additional moisture. Place them in an open container inside the refrigerator to soak up any lingering smells. You can also use citrus peels, such as orange or lemon peels, to add a fresh scent while absorbing odors. Replace the peels regularly to maintain their effectiveness. Any of these options can help keep your refrigerator smelling fresh and clean during storage.
How often should I check on a refrigerator that’s in storage?
While the ideal frequency of checking on a stored refrigerator depends on the length of storage and the initial preparation, a good rule of thumb is to inspect it every few months. This allows you to identify and address any potential issues before they escalate. Look for signs of mold or mildew growth, condensation, or any unusual odors. Addressing these problems promptly can prevent long-term damage.
During your check-ups, it’s also a good idea to ensure the door is still propped open and that your odor absorber is still effective. If you notice any significant moisture buildup, wipe it down with a clean cloth and consider replacing your odor absorber. These regular inspections are a small investment of time that can save you significant effort and expense in the long run, ensuring your refrigerator remains in good condition while it’s not in use.
What should I do before using a refrigerator that has been in storage for a long time?
Before you start using a refrigerator that has been in storage, give it a thorough cleaning, even if it appeared clean when you last stored it. Dust and debris can accumulate over time, and any lingering moisture could have contributed to mold or mildew growth. Use a solution of warm water and mild dish soap to clean all interior surfaces, including shelves, drawers, and walls. Rinse thoroughly with clean water and dry everything completely.
Once the refrigerator is clean and dry, plug it in and allow it to run for several hours before adding any food. This allows the compressor and cooling system to stabilize. Check that the temperature is reaching the desired level. If you detect any unusual noises or odors during this initial operation, consult a qualified appliance repair technician before loading it with food.
