1, yes, the circuit control system is basically normal. Observe whether the LCD screen is normal;
2. When there is an abnormality, it is mostly because the control circuit board fails, and it is impossible to start the work program normally and perform the task;
3. If the screen display is normal, it's mostly the stirring motor, or there is something wrong with its driving circuit, so the motor can't run;
4. If it is judged that there is a motor problem, an experienced person can disassemble the casing (the new machine is not guaranteed after disassembly), find the bidirectional thyristor device on the circuit board, short-circuit it 1 and pin 2, and press the "Start" key, so that the motor rotation will be damaged. Otherwise, it is mostly a motor fault;
5, the new machine, it is best to send it to the warranty point for repair, so as not to make the problem bigger.
