Hey guys- Not sure if this is the right place but not sure where else to look. I have a job site fan with a three position rotary switch: low, med and high. When I have it on any speed but most noticeably on low the fan's RPM will all of a sudden climb but not as high as if it were set to 'med'. Is the switch bad somehow and allowing some current to pass? Motor dying? Any input would be great, Thanks.
