      If the motor of your Wen sander isn't working, it could be due to loose wires in the main plug or a faulty switch. Stop using the tool and contact customer service at 1-(800) 232-1195, M-F 8-5 CST for assistance. Another potential cause is worn brushes. Check and replace the brushes if needed.

      Chris McgeeAug 5, 2025
      If your Wen sander motor is getting excessively hot, it might be due to foreign substances inside the motor. Unplug the unit and inspect for any foreign substances, removing them if found. Another possible cause is applying too high of a load. In this case, let the unit rest for a few minutes and use less pressure during sanding.

      If you're experiencing unusual noises during Wen sander operation and the motor isn't working properly, the switch contact may have failed. Stop using the tool and contact customer service at 1-(800) 232-1195, M-F 8-5 CST for assistance. Alternatively, components may have jammed. Unplug the tool and check that components can move normally. If they cannot, stop using the tool and contact customer service. Finally, too high of a load may have been applied. Use less pressure during sanding operations.

      Frequent sparks on the commutator of your Wen sander may indicate a short circuit in the motor (armature). In this case, have the armature replaced. It could also mean that the carbon brushes are worn out or jammed. Replace the carbon brushes.
