Most refrigerator-freezers and many standalone freezers feature automatic defrost, but for long-term food storage, manual defrost freezers can be the best option.
So when the ice crystals lining the walls of your manual defrost freezer stacks a quarter to a half-inch, it’s time to defrost.
Don’t lose your cool. It’s easier than you think, using these 10 steps adapted from Frigidaire.
Freezer Defrosting Instructions
1. Unplug your freezer. This keeps you from being electrocuted.
2. Open the freezer door and keep it open throughout the process.
3. Remove food into a cooler
4. On upright freezers with a defrost drain, remove the drain plug on the inside floor of the freezer by pulling straight out. To access external drain tube on models with a base panel, first remove the two screws from the base panel. Locate the drain tube near the left center under the freezer. Place a shallow pan under the drain tube. Defrost water will drain out. Check pan occasionally so water does not overflow.
A half-inch garden hose adapter can be used to drain the freezer directly into a floor drain. If your model is not equipped with an adapter, one can be purchased at most hardware stores. Replace the drain plug when defrosting and cleaning are completed. If the drain is left open, warm air may enter freezer.
5. On chest freezers with a defrost drain, place a shallow pan or the Divider/Drain Pan beneath the drain outlet. Pull out the drain plug inside the freezer, and pull off the outside defrost drain plug. Defrost water will drain out. Check pan occasionally so water does not overflow. Replace the drain plugs when defrosting is completed.
If you don’t have a defrost drain, line the freezer bottom with towels to catch
the frost. The frost will loosen and fall. Remove towels and/or newspapers.
6. If the frost is soft, remove it by using a plastic scraper.
7. If the frost is hard, fill deep pans with hot water and place them on the freezer bottom. Close the freezer door. Frost should soften in about 15 minutes, after which you can refer to No. 6. Repeat if necessary.
8. After defrosting, wash inside surfaces and removable parts of the freezer with a solution of two tablespoons of baking soda in one quart warm water. Rinse and dry. Wring excess water out of the sponge or cloth when cleaning in the area of the controls, or any electrical parts. Never use metallic scouring pads, brushes, abrasive cleaners, nor alkaline solutions on any surface.
9. Replace drain plug and food.
10. Close freezer door.
