Storing Your Freezer: Essential Steps for When It's Not in Use

Whether you're moving, remodeling your kitchen, or simply making space for a season, there are times when your freezer will need to be out of operation for an extended period. Many homeowners overlook the proper procedures for storing a freezer that's not in use, which can lead to costly damages, unpleasant odors, or diminished performance when it's time to plug it back in. In this comprehensive guide, you'll discover everything you need to know about how to store your freezer safely when it's not being used.

Why Proper Freezer Storage Is Important

Storing a freezer improperly can result in a range of issues, from mold growth and pest infestations to mechanical problems caused by moisture or dirt. Whether you own a chest freezer, upright freezer, or compact model, the principles for freezer storage are much the same. Taking the right steps will ensure your appliance is ready to use when you need it and maintains its efficiency and lifespan.

Essential Steps for Storing Your Freezer When Not in Use

1. Empty Your Freezer Completely

Before you start preparing your freezer for storage, remove all food items. This prevents spoilage, leakage, and foul odors. Take inventory and use or donate what's still good. If you must store frozen goods elsewhere, now is the time to transfer them.

• Check expiration dates and toss any expired items.
• Wipe down frozen packages before moving them to another appliance to avoid mess.

2. Unplug and Allow to Defrost

Unplugging the freezer is essential. Leave the door open and allow it to defrost naturally to prevent moisture buildup and mold. Plan ahead: depending on the model and the amount of ice buildup, this could take anywhere from a few hours to a full day.

• Place towels around the base to absorb dripping water.
• Avoid using sharp tools to chip away ice, as this can damage the interior lining.

3. Clean Thoroughly Inside and Out

With the interior at room temperature, use a mild soap or baking soda solution (one tablespoon baking soda to one quart of warm water) to clean all surfaces, including shelves and drawers. Be sure to rinse and dry completely. Do not leave any food residue or moisture behind.

• Wipe the gaskets and seams using a soft cloth to remove any grime.
• Clean exterior surfaces to remove dust or sticky spots.

4. Dry the Freezer Completely

Even a small amount of leftover moisture inside your freezer can lead to the development of mold and mildew during storage. Use a clean, dry cloth to wipe down every surface, paying special attention to corners and hidden crevices. Let the door remain open for several hours or overnight to ensure all moisture has evaporated.

• Pro tip: Place a fan nearby to speed up the drying process.

5. Secure or Remove Shelves and Drawers

Loose components, like shelves and drawers, can shift during storage or transport. Remove and wrap them separately or secure them inside the freezer using tape or straps. This step will prevent breakage and make reassembly easier once you're ready to use the freezer again.

6. Protect the Door Seal

The door seal, or gasket, is vital for your freezer's energy efficiency and performance. To keep it supple, apply a thin layer of petroleum jelly to the gasket. This helps prevent drying and warping during long-term storage.

7. Choose a Proper Storage Location

Where you store your unused freezer matters. If possible, store it in a dry, well-ventilated area that's not subject to extreme temperatures. Garages and basements can be good options as long as they're climate-controlled and low in humidity. Direct sunshine or damp corners are not recommended.

• Elevate the freezer using pallets or blocks to protect against unforeseen moisture or flooding.
• Keep it away from corrosive chemicals or dusty locations.

8. Leave the Door Ajar

Storing a freezer with the door closed creates a sealed environment where odors and mold can flourish. Instead, prop the door open with a wedge or block, or use a special "storage mode" latch if your model has one. This simple step allows for adequate air circulation and prevents musty smells.

• If worried about children or pets, use a rope or bungee cord to secure the door open, but out of reach.

9. Cover to Keep Dust Off

Covering your freezer with a breathable cloth sheet can protect its exterior from dust and scratches. Avoid airtight plastic wraps or tarps, as they can trap humidity and promote rust or mold.

10. Inspect Periodically

If you're storing your freezer for several months, check it occasionally. Look for signs of moisture, pests, or odor. This allows you to catch potential issues early and ensures your freezer remains in top condition.

Reactivating Your Stored Freezer: Steps to Take Before Use

When it's time to bring your stored freezer back into service, some preparation is necessary. Here's what you should do before plugging it back in:

1. Inspect for pests, debris, or dust inside and outside the freezer.
2. Wipe down all surfaces again to remove any accumulated dust or cobwebs.
3. Ensure all components (shelves, drawers, seals) are in good condition and reassemble as needed.
4. Check that the power cord and plug are intact with no signs of wear or damage.
5. Plug in the freezer, set the temperature, and allow it to reach the desired coldness before storing food.

Common Mistakes to Avoid When Storing a Freezer Temporarily

While storing your freezer might seem straightforward, many people make avoidable mistakes that could affect the lifespan or functionality of their appliance. Here are some key pitfalls to watch out for:

• Storing it in extreme heat or cold: Excessive temperatures can damage electronic parts or compromise seals.
• Sealing the door completely: No airflow invites mold and odors.
• Leaving food or moisture inside: This leads to rot, stench, and mold growth.
• Storing outdoors or in unprotected sheds: This exposes your freezer to elements, pests, and weather-related damage.
• Skipping periodic checks: Problems like rodents or water damage are easier to fix if spotted early.

Special Considerations for Chest Freezers, Upright Freezers, and Compact Models

Different types of freezers feature slightly different storage requirements:

Chest Freezers

• Ensure the lid is well-supported in an open-ajar position to prevent warping.
• Consider removing the baskets and storing them separately to avoid rust.

Upright Freezers

• Propping the door open is even more important for upright models, as mildew is more likely to form on vertical surfaces.
• Secure the door with a lock or strap if necessary for safety.

Compact and Mini Freezers

• Remove the unit's drip tray (if applicable), clean it, and store it separately to avoid mold.
• Because these models are portable, ensure they're not stacked under heavy items that could cause denting.

Bonus Tips for Long-Term Freezer Storage

• Use silica gel packs or a box of baking soda inside to absorb remaining moisture and odors.
• Label the freezer with a tag or tape indicating when it was last cleaned and stored. This is handy for longer-term storage.
• Keep the instruction manual inside a plastic bag taped to the back for easy reference in the future.

Frequently Asked Questions About Storing Your Freezer

How long can a freezer sit unused?

A properly prepared and stored freezer can safely sit unused for many months, even a year or more, without significant issues. The key is to prevent moisture and maintain airflow inside.

Should I plug in my freezer occasionally during storage?

Unless required by the manufacturer, there is no need to intermittently run the freezer while it is clean, dry, and empty. Keeping it unplugged saves energy and prevents unnecessary wear.

Can I store my freezer outside temporarily?

It is generally not recommended to store freezers outside due to the risk of weather exposure, temperature swings, and pests. Covered and insulated storage is best.

How should I prepare my freezer for a move?

Follow the cleaning and preparation steps above, ensure it's fully dry, and secure all loose parts. Allow it to sit upright for at least 24 hours after the move before plugging in, so the coolant settles.

Conclusion: Store Your Freezer with Care

Taking a little extra time to store your freezer properly pays off in ensuring that your appliance remains odor-free, efficient, and ready for use when you need it again. Remember the basics: empty, defrost, clean, dry, keep the door ajar, and store in a safe location. With these essential steps, you can prolong the life of your freezer, avoid potential headaches, and ensure that it functions just as well when brought back into service. Happy storing!
