It supports both 18V and 21V power systems, making it a versatile replacement part for these popular electric wrenches.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the control board do in a brushless electric wrench?\u003c\/h4\u003e\n\u003cp\u003eA: The control board acts as the brain of the brushless motor system. It regulates the drive voltage, manages the speed-control switch input, and coordinates the motor's electronic commutation — replacing traditional carbon brushes for more efficient and longer-lasting operation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I know if my control board needs to be replaced?\u003c\/h4\u003e\n\u003cp\u003eA: Common signs that a control board may need replacement include the tool failing to start, inconsistent speed response, or a persistent buzzing alarm when the trigger is pressed. Always follow the installation steps in order to rule out assembly issues before concluding the board itself is faulty.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is any special tool required for installation?\u003c\/h4\u003e\n\u003cp\u003eA: Standard screwdrivers suitable for your Dayi wrench model are typically all that's needed.
