The first reason is that the cavity of microwave oven is too dirty. There are a lot of cooking oil stains and food residues around the cavity, which will absorb microwaves, resulting in uneven energy absorption of microwave ovens, leading to overheating and burning food in some places. The solution to this problem is to clean the inner cavity and surrounding of the microwave oven frequently.
The second reason is the power supply problem. If the power supply voltage is unstable, the energy output of the microwave oven may be insufficient or too strong, resulting in food burning. To this end, we can use a stable power cord to ensure the normal work of the microwave oven.
The third reason is the improper time setting. When using the microwave oven, we need to set the time according to the different weights and materials of food. If the start-up time of microwave oven exceeds the time required for food, it will cause food to overheat and burn. The best way to solve this problem is to know the weight, material and time of food before it enters the microwave oven.
The fourth reason is that the microwave oven or food paper has not been removed. Paper can absorb microwaves, but at the same time, it will produce an effect similar to a high-temperature oven, making food easy to burn in a short time. Therefore, the paper should be removed before using the microwave oven.
Finally, when we find burnt food in the microwave oven, we can steam it with lemonade or white vinegar for 2-3 minutes and dry it with paper towels to remove the bacteria and odor hidden in the microwave oven and on the turntable, so as to ensure the safety and convenience of use. Generally speaking, as long as you master some basic knowledge and pay attention to details, you can avoid the failure of microwave cooking and ensure a better quality of life.
