1. First, open the Jiuyang soymilk machine. We can see that there are three metal fittings under the nose, one is connected with the cutter head and the other is a curved heating pipe. The long metal tube probe next to the heating tube is the temperature sensor we are looking for.

2. Secondly, to remove the temperature sensor, you need to open the nose. After opening it, you will find that the temperature sensor is connected to a wire of the bracket, which is directly connected to the temperature sensor and the circuit board that controls it. It forms a loop with the zero line of the heating pipe of the soymilk machine. We just need to remove the wire connecting the temperature sensor from the computer board.

3. Finally, buy the same type of temperature sensor and put it back into the head of the soymilk machine according to the disassembly method.
