Dewalt DCS391 Not Working (SOLVED)
Check the Battery Contacts
One of the most common issues causing a Dewalt DCS391 to malfunction is corroded battery contacts.
Corrosion can interrupt the flow of power from the battery to the saw, preventing it from turning on.
To troubleshoot this issue:
- Remove the Battery: Before inspecting the battery contacts, ensure the saw is turned off and remove the battery pack by pressing the release button on the back of the saw.
- Inspect the Contacts: Examine the battery contacts for any signs of corrosion. If you find any, gently clean them with a wire brush or a contact cleaner.
- Reconnect the Battery: After cleaning the contacts, insert the battery pack back into the saw until it clicks into place.
Check the Battery
If cleaning the battery contacts doesn’t resolve the issue, it’s essential to check the battery’s functionality.
A battery that’s not charged or is malfunctioning can prevent the saw from working correctly. Here’s how to test your battery:
Use a Multimeter: You can use a multimeter to measure the voltage of the battery. Make sure the battery is fully charged, and then connect the multimeter’s probes to the battery terminals.
A healthy Dewalt DCS391 battery should have a voltage close to its rated voltage (usually around 20 volts).

If your battery is indeed the issue, you can replace it following these simple steps:
- Purchase a Replacement Battery: Find a replacement battery that is compatible with the Dewalt DCS391. You can usually find these batteries online or at your local hardware store. Ensure it meets the specifications of your saw.
- Turn Off the Saw and Remove the Battery Pack: Before replacing the battery, turn off the saw and press the release button on the back of the saw to remove the old battery pack.
- Insert the New Battery Pack: Carefully insert the new battery pack into the saw until it clicks into place. Make sure it is securely attached.
- Charge the New Battery: Charge the new battery pack fully before using it for the first time. Follow the instructions provided with the battery pack or charger to ensure it’s charged correctly.
Take the Saw Apart
Sometimes, the problem may lie deeper within the saw’s components, such as the motor or electrical connections.
While taking apart your saw can be a complex task, it can help identify issues that are not apparent from the outside.
