DEWALT DCS7485 FLEXVOLT 60V MAX TABLE SAW General Troubleshooting

Switch Assembly

The switch on this unit is a magnetic safety switch that also serves as a primary circuit interrupter. Internal carbon buildup on the contacts or a weakened magnetic coil causes the switch to drop the connection under the high vibration and amperage draw of the table saw motor, resulting in a 'tripping' sensation. Replacing the assembly restores the integrity of the high-current path.

Motor Control Module (ESC)

The control module manages the three-phase power delivery to the brushless motor. If the internal MOSFETs (metal-oxide-semiconductor field-effect transistors) begin to fail or overheat, the module's firmware will trigger a 'hard stop' to protect the motor from a phase-short. This is perceived as a motor trip, especially when the blade hits the resistance of the workpiece.

Battery Terminal Block

High-vibration tools like table saws can cause the spring tension in the terminal interface to loosen over time. This creates high electrical resistance and localized heat at the battery connection, leading to a significant voltage drop. The saw's internal logic interprets this voltage sag as a depleted battery or a fault, immediately cutting power to the motor.
