May show that the oil on the surface of the board is caused by more or a component foot rust. Wash the display board with washing board water, no washing board water can also be washed with alcohol, but the effect of alcohol washing is not as good as that of washing board water.
The display is locked, this lock may be intelligent mode open, some holiday mode, these are not responsive, but canAdjust the temperature. You can try to hold down the artificial intelligence function key for a long time to unlock, the specific method is as follows: press the "Kinetic energy" key 3, select "Lock", and then press the "Setting" key 4 to confirm, then a horizontal line will appear below "lock", indicating that it has entered the locked state.
Power problem First, you need to determine if you have enough power to run the induction cooker. If the outlet works, but the stove doesn't light, you can try to test whether the outlet can provide power properly with another appliance. If the outlet is out of power, you will need to replace the power supply or repair the outlet. Power chip The power chip of the induction cooker is the control of the induction cooker, you can re-insert the connection pin, or solder the connection point to ensure that the chip is well connected to the motherboard. Check power cables and capacitors Check power cables and capacitors for faults, and if power cables or capacitors are damaged, they should be replaced to ensure that the chip will work properly. Replace the chip If the chip is damaged, replace the chip.
2, check whether the power chip is damaged: Before repairing the power chip, first check whether the power chip is damaged. You can use a multimeter to test the chip induction cooker tm1668 chip has procedures resistance value, if the resistance value is significantly high or low, it indicates that the chip has been damaged. Replace the power chip: If the power chip is damaged, it needs to be replaced. First, remove the induction cooker panel and find the location of the chip.
3, after confirming the chip damage, we need to buy a chip of the same model. Induction cooker tm1668 chip program You can buy on the Internet or local electrical repair shop. After receiving the new chip, place the induction cooker on a clean and flat work surface. screwdriverThe old chip is removed from the circuit board, and the new chip is removed. Make sure to install the new chip properly and connect it to the wires on the circuit board. After making sure that the connection is correct, close the shell of the induction cooker.
1, induction cooker control chip can be programmed. Smart home appliances need to be programmed, the so-called microcomputer control is programmed into the chip, non-intelligent is generally an electromagnetic switch.
2, according to the Douding network query, induction cooker MCU programThe reading and writing method can be realized in the following ways: Through serial communication: the single chip microcomputer can communicate with the computer through the serial port, the program is sent to the single chip microcomputer through the serial port for writing, or the program in the single chip microcomputer is read out. This requires the use of corresponding serial communication protocols and programming methods.
3, induction cooker chip S3F9454BZZ-DK94 are added to the secret, take a new chip with 809 can be written, but to source. Induction cooker cpu program has not yet said that they can "write code" internal errors are useless. Blank film is also useless, only the manufacturer to provide useful.
