Common Dewalt 20v Blower Issues
The Dewalt 20V blower is popular for yard work and cleaning tasks. Many users face common issues that affect its performance. Knowing these problems helps in quick troubleshooting and repair.
Below are the most frequent issues reported by users. Understanding these can save time and money.
Battery And Power Problems
The blower may not start or stops suddenly. Low battery charge often causes this. Faulty battery connections also lead to power loss. Sometimes, the battery fails to hold charge after repeated use. Checking the battery health and connections is key.
Motor Malfunctions
The motor might make strange noises or stop running. Overheating can cause motor failure. Dirt and debris inside the motor block its function. Regular cleaning and avoiding overload protect the motor. A worn-out motor needs professional repair.
Airflow Reduction
Low airflow reduces the blower’s efficiency. Clogged air vents or filters often cause this. Debris buildup inside the blower tube also blocks airflow. Cleaning these parts restores proper air movement. Check for cracks or damage in the blower tube.
Switch And Trigger Failures
The blower may not respond to the trigger or switch. Faulty wiring or worn-out switch parts cause this issue. Dust and moisture can damage internal switch components. Replacing the switch or cleaning contacts often fixes the problem.

Troubleshooting Battery And Charging
Battery and charging issues are common with the Dewalt 20V blower. These problems can stop your tool from working well. Understanding how to troubleshoot battery and charging troubles helps keep your blower ready to use.
Problems often start with the battery or charger. Knowing how to check and care for these parts saves time and money. Simple steps can fix many common issues without professional help.
Checking Battery Health
Start by inspecting the battery for damage. Look for cracks, leaks, or swelling. These signs mean the battery needs replacement. Clean the battery terminals with a dry cloth. Dirty contacts can block power flow. Use a multimeter to check battery voltage. Low voltage means the battery may be weak or dead. Try the battery in another tool. If it does not work, the battery is likely the problem.
Proper Charging Techniques
Use only the charger made for your Dewalt 20V battery. Plug the charger into a working outlet. Insert the battery firmly into the charger. Watch the charger’s light for status. A blinking light might show a charging error. Avoid charging the battery in very hot or cold places. Let the battery cool before charging if it feels hot. Remove the battery once fully charged to prevent overcharging.
Battery Replacement Tips
Replace the battery if it no longer holds a charge. Buy a battery that fits your Dewalt blower model. Check the battery’s voltage and capacity before purchase. Store new batteries in a cool, dry place. Dispose of old batteries properly at recycling centers. Keep spare batteries charged and ready for use. This ensures your blower runs without interruption.
Fixing Motor And Mechanical Issues
Fixing motor and mechanical issues in a Dewalt 20V blower is key to keeping it running well. Problems like weak airflow or strange noises often come from motor or mechanical faults. Understanding how to clean, check, and repair these parts saves time and money.
Cleaning And Maintenance
Start by cleaning the blower regularly. Dust and debris can block airways and cause motor strain. Use a soft brush or compressed air to remove dirt from vents and moving parts. Regular cleaning helps the motor run cooler and lasts longer. Always remove the battery before cleaning to stay safe.
Inspecting Brushes And Bearings
Brushes and bearings wear out over time. Check the carbon brushes for signs of damage or wear. Worn brushes can cause poor motor performance or failure. Bearings support the motor shaft and allow smooth rotation. Listen for grinding noises that may mean bad bearings. Replace worn brushes and bearings to restore proper function.
Repairing Motor Components
Sometimes motor parts break or get damaged. Check the armature and stator for burns or cracks. Damaged parts need replacement to avoid further issues. Use a multimeter to test electrical continuity in motor components. Fix loose connections or broken wires carefully. Proper repairs improve blower power and reliability.
Restoring Airflow Performance
Restoring the airflow performance of your Dewalt 20V blower is key for effective use. Over time, dust and debris can slow down the air output. This section guides you through simple steps to bring back strong airflow. Follow these tips to keep your blower running smoothly and efficiently.
Clearing Air Intake And Nozzle
Start by checking the air intake and nozzle for dirt or blockages. These parts often gather dust, which reduces airflow. Use a soft brush or cloth to clean these areas carefully. Avoid pushing dirt further inside the blower. Clear passageways help air move freely, improving blower power.
Removing Debris And Blockages
Debris inside the blower can cause serious airflow issues. Look inside the blower tube and fan area for stuck leaves or twigs. Use a small tool or compressed air to remove them. Keep the blower unplugged before cleaning to stay safe. Removing blockages restores full air pressure and efficiency.
Ensuring Proper Assembly
Check that all parts fit correctly after cleaning. Loose or misaligned parts reduce airflow and can damage the blower. Follow the user manual for correct assembly steps. Tighten screws and connect pieces securely. Proper assembly guarantees your blower works at its best performance.
Addressing Switch And Trigger Problems
Switch and trigger problems are common issues with the Dewalt 20V blower. These parts control the power flow and speed of the blower. Faulty switches or triggers can cause the blower to stop working or work irregularly. Fixing these problems quickly helps keep your blower running smoothly.
Testing Electrical Connections
Start by checking the electrical connections inside the blower. Loose or dirty wires can stop the blower from working. Use a screwdriver to open the blower casing carefully. Look for any disconnected or damaged wires near the switch and trigger. Use a multimeter to test if electricity flows through the switch. No flow means a problem in the connection or switch.
Replacing Faulty Switches
When testing shows the switch is bad, replace it. Purchase the correct replacement switch for the Dewalt 20V model. Remove the old switch by disconnecting its wires and unscrewing it. Connect the new switch wires exactly as the old one was. Tighten screws and close the casing before testing the blower. A new switch often solves power and trigger issues.
Preventing Future Failures
Keep the blower clean and dry to avoid switch problems. Dirt and moisture cause electrical parts to fail faster. Store the blower in a dry place and clean it regularly. Avoid dropping or hitting the blower to protect internal parts. Check switches and triggers for wear during regular maintenance. Small care steps extend the life of your Dewalt 20V blower.
