How do I replace the control board?
1. For safe operation, unplug the power cord.
2. Remove glue. To remove the glue block that fixes the board, you can buy 75% medical alcohol from the pharmacy and apply it on the glue block. The glue block will soften after one minute and you can use tweezers to remove the glue block.
3. Unscrew the four screws on the four corners of the old control board.
4. Remove the wires on the old control board one by one in order of position, and connect them to the same positions on the new control board one by one. Pay attention to the position and order of the wires and do not insert them incorrectly.
5. Re-fix the four corners of the new control board with screws. Be careful not to tighten a single screw first. Fix the four screws first and then tighten them together. The specific line changing process is shown in the video.
