DeWalt Tool Overheating / Inadequate Cooling

Vacuum body or handle becomes uncomfortably hot during normal use

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked cooling vents, Continuous high-load operation, Internal dust buildup around motor, Failing motor bearings increasing friction

Safety: Stop use and remove the battery. Allow the tool to cool completely.

Clean vents thoroughly: Use compressed air to blow dust out of all vents and around the motor housing.
Limit duty cycle: Use the vacuum in shorter bursts with rest periods, especially in hot environments.
Inspect motor: If the motor area is extremely hot compared to the rest of the tool, bearings or windings may be failing.
Resolution: Replace the motor assembly if overheating persists despite clean vents and moderate use.
