In cooking, we often use microwave ovens, which can be used to make many delicacies, such as steaming fish, making cakes, steaming custards, etc. At the same time, microwave ovens can also quickly heat meals, which greatly Saved us cooking time. After long-term use of electrical appliances, some faults often occur. We need to consider and detect them from many aspects. What should I do if the microwave oven does not heat? Let’s learn with us what to do if the microwave oven does not heat!

What should I do if the microwave oven does not heat?

1. If it still does not work after it is powered on Heating, but its indicator light is on and the turntable is rotating, then its failure is mainly caused by the lack of microwave output of the microwave oven. If the furnace light can light up and the turntable rotates, it means that the circuit before the high-voltage transformer is working basically normally, and if the power control switch is also normal. Then its fault scope is in the high-voltage transformer T and its subsequent circuits. There are only two main reasons: the magnetron power supply circuit does not work and the magnetron has poor contact or damage.

2. When detecting, we need to distinguish it from non-startup faults. After disassembling the microwave oven, we should first rule out the possibility of an open circuit of the power control switch S5. Usually we can use a multimeter to measure it, or we can temporarily short-circuit both ends of the power control switch S5 and then test the machine to judge, and then check the components and parts of the high-voltage circuit. its connection end.

Microwave heating precautions

1. If you want to heat meat, we should not heat half-cooked meat products in the microwave. This is because the half-cooked meat is Bacteria will still grow in the food. When it is heated in a microwave oven again, it is impossible to kill all the bacteria due to the short time. If it is frozen meat food, we must defrost it in the microwave first and then reheat it into cooked food. In addition, meat that has been frozen in a microwave oven must be heated until it is fully cooked if it is then placed in the refrigerator.

2. When heating, the bottom of the furnace should be placed stably to avoid deformation when opening the door, which will affect the sealing of the microwave oven. The microwave oven should be used according to its instructions. If a fire occurs in the oven during use, we should avoid opening the door. We should turn off the power first and wait until the fire goes out before opening the door to cool down. Generally, we should not place the microwave oven close to heat sources, home appliances, sunlight and moisture. The power supply of the microwave oven should be equipped with a dedicated line and connected to the ground wire.
