What Is The Dewalt Miter Saw Reset Button?

The Dewalt miter saw reset button is a built-in safety feature typically found on Dewalt’s corded electric miter saws. Its main function is to protect the motor from potential damage caused by electrical overload, overheating, or a short circuit. When the saw encounters such issues, the reset button trips—cutting off power to prevent further risk. Resetting the button restores functionality after addressing the underlying problem.

Where Is The Reset Button Located On Dewalt Miter Saws?

The reset button is usually a small, round, or rectangular button or switch. Most commonly, it’s located near the base of the motor housing, on the side or rear of the saw. Sometimes, models may place it under a protective cover to prevent accidental presses. Wireless, battery-powered, and entry-level miter saws often do not have a physical reset button and use other forms of electrical protection.

How To Identify The Reset Button

  • Look for a red, yellow, or black button labeled “RESET.”
  • Check the sides or rear beneath the saw’s handle or motor.
  • Consult your Dewalt user manual for the exact reset location for your model.

Which Dewalt Miter Saw Models Have A Reset Button?

Not every Dewalt miter saw model features a physical reset button. Generally, corded 12-inch and some heavy-duty sliding compound miter saws include this protection. Examples include the Dewalt DWS779 and DWS780. Older corded saws and saws designed for high-output jobs are more likely to have reset switches, while newer battery-powered FlexVolt or other cordless models rely on advanced circuit protection inside the battery pack or charger unit.

Typical Dewalt Miter Saw Models With Reset Button

  • Dewalt DWS779 12-Inch Sliding Compound Miter Saw
  • Dewalt DWS780 12-Inch Double Bevel Sliding Compound Miter Saw
  • Dewalt DW715 12-Inch Single-Bevel Compound Miter Saw

Refer to your user manual or product label if you are unsure whether your model includes the reset feature.

Why Does The Reset Button Trip On Dewalt Miter Saws?

The Dewalt miter saw reset button trips automatically as a protective measure. The button will disengage power from the tool to avoid hazardous situations. Here are the primary reasons this occurs:

  • Overload: Pushing the saw motor beyond its rated limits or cutting very dense material can overload the system.
  • Overheating: Extended or heavy-duty operation causes the motor to overheat, triggering the reset mechanism.
  • Electrical Short: Wiring faults, loose connections, or exposed wires may short the circuit.
  • Dull or Misaligned Blade: A blade that is not sharp or correctly aligned causes extra resistance, increasing motor strain.
  • Faulty Extension Cords: Using cords longer or thinner than recommended can cause voltage drops and contribute to overloads.

Safety Precautions Before Pressing The Reset Button

Before resetting, it’s crucial to ensure safety for both the operator and the tool. The following steps outline best practices before pressing the Dewalt miter saw reset button:

  • Turn Off And Unplug: Fully power down and disconnect the miter saw from the electrical outlet.
  • Cool Down: Wait several minutes to allow the motor and internal components to cool.
  • Inspect For Damage: Examine the saw for visible issues such as frayed wires, scorch marks, or foreign objects near the blade.
  • Check Blade Condition: Make sure the blade is sharp, properly mounted, and not jammed by debris.
  • Protective Gear: Always wear eye protection and avoid loose clothing or jewelry when troubleshooting or resetting the tool.

How To Properly Use The Dewalt Miter Saw Reset Button

Once safety checks are complete and any hazards identified, use the reset button to restore saw function as follows:

  1. With the saw unplugged, press and hold or firmly press the reset button. You should feel or hear a small click.
  2. Plug the saw back in and set the power switch to the ON position.
  3. Observe the saw: If it powers up and works normally, the problem is likely resolved. If it trips again, further troubleshooting is needed before repeating the process.

When To Avoid Resetting

  • If you smell burning plastic or see smoke, unplug immediately and do not press reset.
  • If wires are exposed or insulation is melted, seek professional repair.
  • A reset button that won’t stay engaged is a sign of internal motor failure or a wiring fault.

Troubleshooting Repeated Reset Button Trips On Dewalt Miter Saws

If your reset button continues to trip after following the prescribed steps, it means a recurring fault exists. Examine the following common causes and troubleshooting tips:

Check Power Supply And Extension Cord

  • Voltage should be consistent with the saw’s requirement (often 120V in the US).
  • Use only heavy-duty extension cords, minimum 12-gauge for up to 50 feet and 10-gauge for longer distances.
  • Inspect extension cords for wear, cuts, and proper grounding.

Blade Condition And Alignment

  • Replace dull or chipped blades.
  • Check mounting bolts are secure and the blade is properly aligned with the fence and miter slots.

Clean Motor Vents And Housing

  • Dust or debris can block cooling vents, causing overheating. Regularly use compressed air to clean the motor vents and under the blade guard.

Check For Obstructions

  • Foreign objects or offcuts may jam the mechanism. Always remove material scraps from the cutting area between uses.

Inspect For Internal Electrical Problems

  • If none of the above address the issue, internal wiring, brushes, or switches may need replacement. These jobs are best left to a certified repair shop or Dewalt service center.

Best Maintenance Practices To Prevent Reset Button Issues

Preventive maintenance keeps your Dewalt miter saw running and reduces stress on the reset button circuit. Consider implementing the following routine practices:

  • Blade Care: Frequently sharpen or replace saw blades. Matching the blade to the material type lowers motor strain.
  • Worksite Cleanliness: Use shop-vacuum systems with dust extraction on every cut, and brush away wood chips after use.
  • Electrical Checks: Periodically inspect all cords, switches, and plug connections for wear, cracks, or exposed copper.
  • Routine Testing: Run the saw briefly at the start of each day, without cutting, to verify normal sound and operation.
  • Motor Cooling: If using the saw continuously, pause every 20–30 minutes to let the motor cool before proceeding.
  • Proper Storage: Store the miter saw in a dry, well-ventilated location when not in use to protect sensitive electronic and moving parts.

When Should You Consult A Technician Or Dewalt Service?

Sometimes, professional help is necessary if the Dewalt miter saw reset button frequently trips or fails to restore function. Contact Dewalt service or a qualified technician under these scenarios:

  • Repeated Resets: The saw cannot operate for more than a few minutes after a reset.
  • Electric Odor or Smoke: Signs of burning, melted casing, or smoke from vents demand immediate attention.
  • Physical Damage: Switches, reset buttons, or wires appear damaged or hang loose from the tool.
  • No Power At All: Saw doesn’t work, even after a reset and different extension cord/outlet has been tried.

For warranty repairs, always have your purchase proof and serial numbers ready. Dewalt provides nationwide service centers and a US-based customer support line for guidance.

Frequently Asked Questions About The Dewalt Miter Saw Reset Button
