/1. First, tear off the nameplate at the bottom of the rice cooker. If there is a screw hole, turn it clockwise with a Torx screwdriver and set it aside. Then you can take off the cover of the rice cooker. If there are wires connected, you need to remember the connection position of the wires and then remove them one by one. If you can't figure out these lines, you can watch the instructional video. 2. After the cover of the rice cooker is removed, you can see that there is a key board, that is, a control panel at the joint between the cover and the internal machine. You can tap the key board on the cover plate from the gap with a flat screwdriver, being careful not to break the key, and then remove the connection point. 3. After disassembly, overhaul the circuit board and the key control panel, and gently brush the key joint with a small dry brush. This place is the easiest place, so don't damage the circuit components, just repair the fault point. Install according to the photos taken before, and don't press the wrong line. If there are instructions, you can refer to the above disassembly and installation methods.
