How to Prevent Accidental Freezer Defrosting

Accidental freezer defrosting can cost you hundreds of dollars in lost frozen food. Potential problems are greater for freezers that are out of sight, as you may not notice the freezer defrosting until too late. However, you can prevent accidental freezer defrosting with a few simple steps.

Difficulty: Moderately Easy

Instructions

1. Maintain a constant power supply to the freezer. Make sure the plug and cord are out of the way so they won't be accidentally pulled out. You can also have a backup power supply, like a generator, on hand.

2. Cover any dials or switches with tape. Some freezers or refrigerators have a defrost switch or dial that will go if accidentally hit. By placing tape over the switch or otherwise making sure that it can't be accidentally engaged, you'll prevent a defrost when you don't want it.

3. Seal the lid of the freezer tightly each time you close it. For older, chest-style freezers that don't stay shut, place something heavy on top of the freezer to keep the lid down. If neccessary, replace the seals or latches and make sure your food isn't preventing the lid or door from shutting tightly.

4. Place a wireless thermostat in the freezer and keep the receiver in a conspicuous spot. This way, you can keep an eye on the temperature inside the freezer and make sure that it doesn't start to defrost.

5. Watch the freezer for signs of accidental freezer defrosting. Either keep the freezer somewhere that you pass by regularly during the day, or make a habit of checking for signs of defrost.
