hello guys
I am with problem management, 52-3 error appears indicating sensor malfunction YAM, the box that is adjacent and connected to the board of directors, I move the sensor and the display gives the SAS code buffer, the error 52-1, I am not wrong is the sensor itself (faulty), the motor direction is good! I've seen insulation, brushes, I'll test with direct current to see if they have any more. has anyone gone through this and can give me a hint
