The Best Ways to Defrost a Badly Iced Upright Freezer
Even the best upright freezers are in need of defrosting at some point. Because few homeowners will want to take the freezer outdoors for defrosting, it is necessary to tackle the challenge of keeping the floor of your house dry while removing ice build-up that prevents the freezer from performing at an optimum level.
Start by placing all of your frozen food in a cooler with ice packs, unplug it and then try one of these techniques.
Hot Water Balloons
Several medical hot water balloons can be used to thaw a freezer. When filled with hot water, these balloons can emit heat for several hours before needing to be refilled. Start by unplugging the freezer and placing a plastic tray underneath it. If a large enough plastic tray is not available, consider using heavy duty garbage bags instead. Lay towels onto the floor and use two to three garbage bags, one inside the other, to create a water catcher. Place the garbage bags on top of the towels, open, as if you were going to put the freezer in the garbage bags. Roll the freezer onto the bags and pull them up along the sides. Using several, heavy duty bags together will create an impermeable barrier for the water. Fill the water balloons with hot water and place inside the freezer with the door open.
Hair dryers are a useful tool when defrosting a badly iced upright freezer. After the freezer is empty and the appropriate water catcher has been put in place, it is time to use the hair dryer to slowly thaw the ice. While this process can be quicker than using other methods, it has many more risks. To start, keep the plugged in hair dryer away from any water to avoid electrocution. Always stand several inches away from the freezer while using a hair dryer for defrosting. Keep blow dryer on medium heat to avoid melting the internal plastic of the freezer. This process can also be tiring because it is necessary keep the hair dryer moving back and forth and up and down on the ice.
Hot Water in a Pot
Filling a large household pot with boiling water will also defrost an upright freezer. Do not boil the water in the pan and then place it in the freezer. The heat from the pan could melt plastic insulation or the plastic coating on the shelves of the freezer. Set up the necessary water catcher at the base of the freezer and then place the boiling water inside the freezer. The downfall to this option is that the cold freezer will cool down the boiling water quickly and it will need to be refilled frequently until the freezer is fully defrosted.
