Induction cooker safety tube is good, but the reason is not powered on, the reason is generally that the switching power supply is easier to break (the power supply with the power transformer is less bad).
The common reasons and maintenance methods are as follows:
1, most of it is due to the switching power supply IC damage, induction cooker power supply IC there are many places can not buy, then you can also use the power transformer instead of the switching power supply (general switching power supply only two sets of voltage output, one DC 15V ~ 18V, another DC 10V ~ 12V, and then into 5V for the CPU), that is, the original IC removed without use, Find a transformer with appropriate power (choose a transformer with two sets of AC output, one set of about 8V and the other set of 13V ~ 15v), and add two bridge piles.
2, with the switch tube, the switch tube damage is easy to buy.
3. One of the two pulse rectifier diodes of the switching power supply is damaged.
4, there are also many machines due to the motherboard or panel moisture, leakage caused by cleaning, dry.
The induction cooker is not powered on because the 15A inside the machine is burned off. It cannot be replaced immediately. It is also necessary to further check the circuit, is caused by the obvious short circuit, the general IGBT is definitely the breakdown of the power is not powered on because the internal fuse is burned, causing the fuse to burn the reason is the power tube short circuit. Or silicon bridge breakdown. First insurance burn le... The second rectifier bridge broke down the associated triode breakdown... The induction cooker has broken down
Supor induction cooker insurance, if it is normal, but there is no electricity, it may be because the charging line is wrong.
