The defrosting process for a fridge can vary depending on the size and model and the level of frost buildup inside.
In general, defrosting a refrigerator can take anywhere from several hours to a full day. Turning off the fridge and unplugging it before defrosting is important to prevent damage.
To speed up defrosting, you can place towels or a tray under the refrigerator to collect water, use a hair dryer on low heat to melt the ice or place bowls of hot water inside the refrigerator.
Once the defrosting process is complete, wipe down the interior with a clean, damp cloth and allow the fridge to dry completely before moving it.
