The Ender 3 V4 toolhead board (often referred to as the extruder daughterboard or print head PCB) serves as the central wiring hub for your printer's hotend components, consolidating connections for the thermistor, heater cartridge, part cooling fan, and hotend fan into a single compact board. If you're experiencing intermittent temperature readings, fan failures, or physical damage to the board, replacing it is a straightforward repair. This guide provides step-by-step instructions for safely removing the old toolhead board and installing a new genuine Creality replacement, including proper cable routing and connection verification.
