If you're experiencing issues with your Ender 3 V3 SE due to a failed toolhead PCB, this original Creality replacement part will get your printer back up and running smoothly.
One of the most common reasons for replacing this PCB is the dreaded blob of death—a print failure where molten filament accumulates around the hotend, sometimes encasing components in plastic. If not caught early, it can lead to tricky cleanup operations. Worse, excessive heat and force during removal may cause connectors to detach from the PCB, making reattachment difficult or requiring delicate soldering or gluing.
Save time and hassle by simply replacing your board.
