Hi Everyone. This is my first time posting here. I hope someone can help me out. I have a 20V DCW210 Random Orbit Sander. A couple weeks ago, the sander stopped regulating its speed when off the work piece, and then had no torque when it engaged the work piece. I discovered that my belt (#DWB-N430442) had snapped. So, thinking that would cure everything, I ordered a new one and installed it. That did fix the issue of the pad continuing to spin when I turned off the tool, but the pad still spins right away when I turn the tool on, and it still has no torque when engaged with the workpiece. Help!
