Official Power sander parts

Is your power sander operating intermittently, or has it completely stopped working? Assessing its condition prior to the failure is the place to begin the repair process. Was it running too hot before it failed? Did it not turn on after being unused for some time? Thinking through the events leading up to the failure can point you to which part or parts need to be replaced. Power sanders spin at high speeds, and depending on how you use your tool, various issues can occur over time.

Five sander issues that can be easily fixed

  1. Sander doesn’t turn on—Faulty switches and power cables can be the issue when a power sander doesn’t turn on. Fortunately, these items can be replaced. It’s also a good idea to check to make sure the electrical outlet you’re using has the right amount of voltage to support the tool.
  2. Tool is too hot—When you use a power tool for a long period of time, the tool can overheat and appear to fail. Turn it off and let it cool down before attempting to use the tool again. If the problem persists, then the brushes may be worn and need to be replaced. Check the condition of the holder brush to determine whether it needs replacement.
  3. Sander isn’t spinning at the proper speed—The tool may need to be cleaned, or the power cord might be damaged and need to be replaced.
  4. Sparks are occurring during use—If you see sparks and smoke coming from the tool, these signal an internal problem with the sander. It’s likely that the motor brushes or the armature needs to be replaced.
  5. Sander is sluggish—A power sander that labors to perform may need a thorough cleaning. Use canned air to blow away debris in switch levers and ventilation screens. Never clean the tool by pushing sharp or pointed items into openings along the body.

Common parts that can be replaced on a power sander

  • Armature—The armature spins the drive shaft. Most armatures will also include an armature bearing, a fan and a commutator end bearing.
  • Brush holder—The brush holder has wiring that connects the brushes to the switch assembly.
  • Switch assembly—Switches and power buttons allow you to adjust the speed of the tool as you work.
  • Pad bearing—The pad bearing allows the sanding pad to spin freely. If you can’t spin the pad with the tool turned off, then check the condition of the pad bearing.
  • Power supply cord—A frayed power supply cord should be replaced right away.
