The best way to store a microwave is to keep it in a dry, climate-controlled area on a sturdy, flat surface with at least 3 inches of clearance on all sides for ventilation. If you must store it long-term, clean it thoroughly first, leave the door slightly ajar, and cover it loosely with a breathable cloth to prevent dust buildup and moisture trapping.

Quick Answer

Store a microwave in a dry, ventilated space, cleaned and door ajar, covered with a breathable cloth. Avoid extreme temperatures and stacking heavy items on top.

  • Location: Store in a dry, indoor area with stable temperature between 50°F and 85°F.
  • Ventilation: Leave at least 3 inches of space around all vents to prevent overheating.
  • Door Position: Prop the door open slightly (use a rolled towel) to prevent mold and odors.
  • Covering: Use a cotton sheet or cloth; never plastic wrap or airtight covers.
  • Stacking: Do not stack anything heavy on top of the microwave; it can damage the casing and internal components.

1. Clean and Dry Your Microwave Thoroughly

Before storing, give your microwave a deep clean. Wipe down the interior with a mixture of equal parts water and white vinegar to remove food residue and odors. Pay special attention to the turntable, roller ring, and door seals. Rinse with a damp cloth and dry completely with a soft towel. Any leftover moisture can lead to mold growth during storage. For the exterior, use a mild all-purpose cleaner or soapy water, then dry thoroughly. Remove any removable parts like the glass turntable and wash them separately in warm soapy water; let them air dry completely before placing them back inside.

2. Choose the Right Storage Location

Select a spot that is dry, cool, and away from direct sunlight or extreme temperature changes. Ideal locations include a pantry shelf, a garage cabinet (if climate-controlled), or a spare closet. Avoid storing in areas prone to humidity like basements or attics, as moisture can damage internal electronics. Ensure the surface is level and sturdy enough to support the microwave’s weight (typically 30-50 lbs). Do not place it on top of other appliances that generate heat, such as a refrigerator or toaster oven.

3. Prepare the Microwave for Storage

  1. Remove the power cord and wrap it loosely around the microwave or secure it with a twist tie; do not kink or bend sharply.
  2. Prop the door open slightly using a rolled-up dish towel or a piece of cardboard to allow air circulation and prevent seal deformation.
  3. If you have the original packaging, use the foam inserts and box for maximum protection. Otherwise, wrap the microwave in a moving blanket or thick layer of bubble wrap, securing with tape.
  4. Place a layer of cardboard or a soft cloth inside the cavity to prevent the glass tray from shifting and chipping.
  5. Label the box or stored area as “Microwave – Fragile” for clarity.

4. Cover the Microwave Properly

Use a breathable cover like a cotton sheet, muslin cloth, or a dedicated appliance cover with ventilation holes. Avoid plastic bags, vinyl covers, or airtight wraps because they trap moisture and promote condensation, which can lead to rust or electrical damage. If stacking is unavoidable, place the microwave on top of sturdier items (never underneath) and ensure nothing presses against the door or vents. For long-term storage, check on the microwave every few months to air it out and look for any signs of moisture or pests.

5. When You Take It Out of Storage

Before plugging in, inspect the microwave for any visible damage, especially the power cord and plug. Remove the cover and let the microwave sit at room temperature for at least 2 hours if it was stored in a cold area; this prevents condensation inside the electronics. Wipe down the interior with a dry cloth, replace the turntable, and run a test with a cup of water for 1 minute to ensure everything works. If you notice any unusual smells or sounds, unplug and consult the manual or a professional.

Pro Tips

  • Place a small box of baking soda inside the microwave to absorb odors during storage.
  • If storing for more than six months, remove the glass turntable and wrap it separately in bubble wrap to prevent breakage.
  • Use a furniture dolly to move a heavy microwave; lifting incorrectly can damage the magnetron.
  • Keep the user manual and any accessories (like the rotating ring) taped to the top of the microwave so they’re not lost.

Common Mistakes to Avoid

  • Storing a microwave upside down or on its side can cause internal components to shift or break.
  • Wrapping the microwave in plastic wrap or a non-breathable cover traps moisture and leads to rust.
  • Leaving the door closed tightly during storage encourages mold growth and degrades the door seal.
  • Stacking heavy items like books or boxes on top of the microwave can crack the control panel or damage the door hinges.

FAQ

Can I store a microwave in the garage?

Yes, but only if the garage is climate-controlled and stays between 50°F and 85°F. Extreme heat or cold can damage the electronics and shorten the microwave’s lifespan.

Should I remove the glass turntable before storing?

Yes, it’s a good idea. Remove the turntable and wrap it separately to prevent it from shifting and cracking inside the microwave during movement.

How long can a microwave be safely stored?

A microwave can be stored for years if kept in a dry, stable environment. However, check it every six months for signs of moisture, rust, or pests, and run a short test before regular use.

Is it safe to store a microwave on its side?

No. Always store a microwave upright. Storing it on its side can cause the magnetron tube to shift or break, and may also damage the door alignment.

The Bottom Line

Storing a microwave correctly preserves its performance and extends its life. By keeping it clean, dry, and ventilated, you can avoid costly repairs or replacements. When you’re ready to use it again, a quick inspection and test will ensure it’s safe and ready to heat your meals.
