Expert Advice on Storing an Unused Freezer
An unused freezer can be both a blessing and a challenge--whether you're upgrading appliances, preparing for a long vacation, or just freeing up space. To benefit from your investment and prolong the appliance's lifespan, you must store it correctly. This expert guide covers all aspects of storing an unused freezer, so you'll avoid unnecessary repairs, inefficiency, or health risks when you need to bring it back into service.
Why Proper Freezer Storage Matters
Freezers are built to last, but improper storage can lead to mold buildup, component failure, or even permanent damage. Whether you have an upright or chest model, following best practices ensures your appliance will work efficiently for years to come. Improper storage may turn a functional freezer into a potential hazard or write-off.
The Risks of Storing a Freezer Incorrectly
- Mold and unpleasant odors from trapped moisture or leftover food residue
- Rusting of internal or external parts due to lingering humidity
- Electrical and mechanical damage from pests, temperature fluctuations, or water leaks
- Inefficiency and higher energy consumption when returned to service
Let's dive into a step-by-step process, based on expert advice, for safely storing an unused freezer.
Step-by-Step Guide: How to Store an Unused Freezer
1. Unplug and Defrost Your Freezer
Unplugging your freezer is the first essential step. Turn off the appliance, remove the plug from the wall, and open the door to let the interior warm up. For self-defrosting models, this is simple; for manual-defrost versions, allow sufficient time for all ice to melt. Place towels or a shallow tray at the base to collect water from melting ice.
- Remove all food: Empty out every item, even those in the back corners and drawers.
- Dispose of any perishables: Use, donate, or throw away anything that won't keep.
2. Deep Clean and Dry the Interior
A spotless freezer is essential before storage to prevent mold, mildew, and unpleasant smells. Use mild soap, warm water, and a clean cloth or sponge. For stubborn stains or odors, try a paste of baking soda and water or a solution of vinegar and water.
- Clean all shelves and drawers: Remove, wash, dry, and replace them before storage.
- Wipe the door gasket: Gently clean the rubber seal, as mold can easily develop here.
- Dry thoroughly: After cleaning, leave the door open for several hours.
Tip: A moisture absorber or a box of baking soda inside the freezer can help keep it fresh during storage.
3. Secure and Protect Power Cords
Coil the power cord neatly and secure it to the back of the freezer with a twist tie or plastic strap. This prevents tripping hazards and protects the cord from bending or damage. If storing for the long term, consider wrapping the plug in a small plastic bag to keep dust and moisture out.
4. Choose the Right Storage Location
Where you store your unused freezer can make or break its longevity. Freezers aren't designed to handle every climate or surface. The ideal location keeps the appliance safe from environmental risks, pests, and physical damage.
- Indoors is best: A climate-controlled garage, utility room, basement, or spare room is ideal.
- Keep away from direct sunlight: Excessive heat can warp plastic parts, fade finishes, or cause gaskets to deteriorate.
- Avoid damp or humid areas: High moisture leads to rust, corrosion, and mold. If only a shed or basement is available, use a dehumidifier.
- Elevate the freezer: If storing in a basement or anywhere prone to flooding, place the freezer on wooden blocks or a sturdy pallet.
- Allow airflow: Position the appliance at least a few inches from walls and never wrap it in plastic, as this can trap moisture.
5. Prop the Door Open Slightly
Never store a freezer with the door fully closed. Even after cleaning and drying, residual moisture can create a perfect environment for mold and mildew. Use a small wedge, towel, or even the freezer's own ice scraper to prop the door open about an inch. This allows air to circulate and keeps the interior fresh.
6. Cover the Freezer (But Not Tightly)
Protect the exterior from dust and debris with a breathable cover. Use a cotton sheet or purpose-made appliance cover--never plastic, which can trap moisture and promote rust or mold formation.
7. Periodically Inspect the Freezer
Even in long-term storage, routine checks are essential:
- Look for signs of moisture or mold: Wipe dry if needed and leave door propped open.
- Check for pests: Ensure rodents or insects haven't moved in.
- Routinely air out: Every few months, open the door wide for a couple of hours and replace the baking soda.
Special Tips for Storing Freezers in Cold or Hot Climates
Temperature extremes can damage your unused freezer. If you must store it in a garage, shed, or outdoor location, consider the following:
- In winter: Freezing temperatures can cause oil in the compressor to thicken or refrigerant to separate. Move the freezer inside, if possible. At minimum, avoid sudden temperature changes that could crack internal parts.
- In summer/heat: High temperatures degrade gaskets and speed rust. Store in the coolest, shaded area available. Never store in direct sunlight.
- Humidity control: Use a desiccant, silica gel, or a dedicated dehumidifier if moisture is a problem.
Short-Term Versus Long-Term Freezer Storage
How you store your frozen appliance also depends on the expected length of storage. Here's what the experts recommend:
Short-Term Storage (Under 1 Month)
- Defrost and clean thoroughly
- Keep in a temperate indoor area
- Door may stay slightly ajar, but not wide open
- No need for extensive covering, just protection from dust
Long-Term Storage (More than 1 Month)
- Deep clean, sanitize, and dry completely
- Use baking soda (or a commercial odor absorber) inside
- Elevate to prevent water damage
- Regularly check inside for pests or mold
- Replace moisture absorbers periodically
Prepping the Freezer for Use After Storage
After months or years in storage, it's not enough to just plug in your freezer and start using it. Give it a careful inspection and action plan:
- Examine for damage: Check gaskets, electrical cords, and the interior for cracks, pests, or moisture.
- Clean thoroughly: Wipe out the interior, refresh with new baking soda, and clean all surfaces.
- Allow to settle: If the freezer has been tilted or moved, let it sit upright for at least 4 hours (upright model) or 8-24 hours (chest freezer) before restarting. This protects the compressor and refrigerant system.
- Start up empty: Run the freezer empty for a few hours to ensure it achieves the correct temperature before adding food.
Expert Answers to Common Freezer Storage Questions
Can you store an unplugged freezer outside?
It's strongly discouraged. Outdoor conditions expose your freezer to moisture, pests, temperature swings, and UV rays. If you must, elevate it off the ground, use a breathable cover, routinely air it out, and bring it inside at the earliest chance.
What is the best position to store a freezer?
Keep the freezer upright at all times. Storing it on its side or back can affect the oil in the compressor and lead to a system failure. If it must be shifted, wait the recommended time before plugging it back in--usually 24 hours to allow fluids to settle.
Is it OK to store items inside the unused freezer?
While it might be tempting to use the empty cavern as extra storage, experts caution against filling your stored freezer with anything--especially food or perishables. Moisture or residue from the items can attract mold or pests. If you must use the space, limit it to clean, dry, sealed plastic bins and never overfill--the door must remain slightly open for airflow.
Should you clean the coils before storage?
Yes. Remove dust and debris from the compressor and coils at the back or base of the freezer. This prevents buildup, extends the life of the unit, and ensures efficient cooling when returned to service.
How do I keep pests out of my stored freezer?
- Clean all food residue before storage
- Seal gaps with steel wool or caulk if stored in a garage/shed
- Check inside and outside periodically for nests or droppings
Freezer Storage Mistakes to Avoid
- Skipping defrosting and cleaning: Leading to foul odors and mold
- Storing with the door or lid tightly shut: Encourages moisture and mildew buildup
- Using a plastic/vinyl cover: Traps humidity and speeds up corrosion
- Placing in a location with drastic temperature swings: Risk of damage or performing poorly upon reuse
- Storing on its side or upside-down: Likely destroys the compressor, costing more to repair than replace
Conclusion: Prolong Your Freezer's Lifespan with Proper Storage
