Guest Azzhol_06@yahoo.com Posted June 9, 2014 Report Share Posted June 9, 2014 Trying to figure out this angle grinder. When you flip the switch it acts like it is locked up. Almost like the polarity in the motor is fighting itself. Has anyone had this problem before? Quote Link to comment Share on other sites More sharing options...
Anonymous Posted June 9, 2014 Report Share Posted June 9, 2014 After you unplug it can you spin the wheel by hand? Verify that the locking mechanism isnt depressed? Quote Link to comment Share on other sites More sharing options...
Guest Guest Posted June 10, 2014 Report Share Posted June 10, 2014 Yes I think I it is the variable speed controller. I cannot get and resistance when I try to check it no matter where I move the dial Quote Link to comment Share on other sites More sharing options...
Anonymous Posted June 10, 2014 Report Share Posted June 10, 2014 Not sure on that one. I know that you can check for continuity on potentiometers, but I dont know if that variable speed controller would actually be classified as a potentiometer or not. Best bet would be to check warranty before you tear it apart any further. Quote Link to comment Share on other sites More sharing options...
