1. The coil plate of the induction cooker is generally not short-circuited, and it is a very thick wire composed of multiple enameled strands. The current here is very large, which is a high-frequency alternating current. Once short-circuited, the fuse will be burned out and the short-circuit point It can be seen with the naked eye, and it will be burnt into a carbon black shape. The black color of the coil plate is definitely not a short circuit, but is caused by the long-term high temperature of the insulating paint.
2. If the induction cooker has a power coil plate, it is generally normal. Disassemble the machine to check whether the coil plate terminal is well connected to the main board, and whether the lead wire and coil are broken, scratched, burnt or melted, etc. If all are normal, the coil plate is good. Due to long-term work, the paint film will age and change color, and it is normal for it to become dark and black.
The coil disc is made of multiple strands of mutually insulated enameled wire. Generally, there will be short circuits due to pinholes or wire scratches of the enameled film, and contact with metal. There will be click marks at the short circuit. In severe cases, the coil will be partially burnt and melted. It's easy to check.
Expansion information:
1. Ceramic plate dirt removal: Ceramic plate is one of the commonly used panels of induction cooker, which has the characteristics of convenient cleaning. If there is dirt on the ceramic plate, wipe it with a soft cloth dampened with water; if there is oil, wipe it with a soft cloth dipped in toothpaste, but it should be noted that before cleaning, remember to cut off the power to prevent burns. In addition, if the ceramic plate is discolored, wipe it with toothpaste or detergent to make it bright as new.
2. Yellowing and cleaning of the panel: If the induction cooker panel is a domestic panel, the panel will be slightly discolored after a long period of use, and it can be wiped with a toothbrush and toothpaste. In normal use, be careful not to burn it dry, so that the bottom of the pan will be scorched and the panel will also change color. In addition, do not put newspaper on the panel before turning it on.
3. Fan cleaning: The induction cooker will be equipped with a dissipating fan. If the fan is blocked by dust, use a soft brush to clean up the machine, but it will not be installed after the machine is disassembled, which will affect the later use of the induction cooker.
