Learn Morerunaway condition. This first failure state is thus the short circuit of the P-N, base-collector junction. This transistor failure is often caused by bad capacitors. It is extremely common to find output filter capacitors that are swollen or leaking electrolytic material. Any capacitor that is swollen or leaking should be replaced.
Learn MoreHigh voltage, high amperage, and poor capacitor manufacturing are mostly to blame for run capacitor failure. We show all of this in action with a few field tests, including reading inrush amps on the start winding (0) and then the run winding (60). According to our results, the motor behavior on startup doesn''t affect the amount of …
Learn MoreYou can probably push it or the caps around it a bit to make the printing visible, at least enough to see whether it''s a Class X or Class Y capacitor. Generally, the former is designed to fail as a short. In typical use, that means failure blows a fuse. A Class Y capacitor is designed to fail open.
