Common faults and maintenance methods of induction cookers

If the entire induction cooker does not react and there is no phenomenon of a bomber, even if the fuse on the top cover of the induction cooker is not burned out, it can be preliminarily determined that the power management chip is broken. If the power management chip of the electromagnetic furnace maintenance is broken, and there is no 18V voltage required for the fan drive and 5V voltage required for the panel CPU, the phenomenon of the overall machine not working will occur. Replace the power management chip.
If you encounter the situation of opening the induction cooker for safety during the maintenance process of the induction cooker, first remove the wire of the furnace coil, reinstall the fuse, and then measure the voltage of the rectifier output. If there is a voltage of 310V, it proves that the power tube GBT is broken, and the voltage is replaced with a component of the same specification. As long as the component replacement method or the electromagnetic furnace maintenance tester inspection method is used to identify the fault point and repair it, the problem can be solved.
In the maintenance analysis of the induction cooker, the focus is on checking whether there is a short circuit or open circuit in the temperature detection thermistor next to the power pipe. When there is a short circuit or open circuit, the voltage will be unstable, and the internal circuit will automatically close due to its protective function. Check if the connection plug of the temperature detection thermistor of the pot has poor contact. If there is a problem with poor contact, it can be solved by re welding.
Check if the resistance value of the temperature detection circuit of the power tube increases and if there is any maintenance phenomenon of an open circuit electromagnetic furnace. When there is an abnormality in the resistance, a voltage abnormality will occur, and the internal circuit will work, outputting a closed signal. Due to the poor CPU performance of the induction cooker, the internal circuit may malfunction and may also cause the induction cooker to alarm or automatically shut down.
