HOW TO DIY Repair.  Quick video describing the issue with M18 tools and possibly M12 tools where the tool suddenly stops working.  In most cases the entire electronics assembly is a single replaceable component.  Common problem is sudden loss of speed, erratic speed, slowing down and speeding up, dead, broken.  Inspect your anvils and rotor before ordering parts to make sure it is just the trigger switch, battery connector, LED, stator, circuit board, wiring, speed selector assembly.  

I think it is a heat issue as the tool ages.  I had two go down with the same issue at just about 5 years old which is also the warranty period.  This is a good solution for expensive M18 tools.  For cheap tools, just go to the pawn shop to get a replacement.
