After a microwave oven is turned off, it typically cools down relatively quickly. The duration for which it stays hot can vary depending on factors such as the specific model, the amount of food that was heated, and the insulation of the microwave. In general, a microwave oven will begin to cool down immediately after being switched off and should reach a safe, cool temperature within a few minutes.
However, it's important to note that certain parts of the microwave, such as the interior walls and the turntable, can retain heat for a bit longer than the rest of the appliance. This residual heat is normal and should dissipate within a short period.
To avoid any potential burns or accidents, it's advisable to use caution when removing items from the microwave after cooking. Use oven mitts or protective gloves and be mindful of the residual heat that may be present. Additionally, always follow the manufacturer's instructions and safety guidelines provided with your microwave oven to ensure safe operation and handling.
