I have a TAZ 6, which has been running great for over a year. The thermister went out, I replaced it, then noticed that the heat brake fan was not spinning. Ordered a replacement, and the new one is not spinning.
Red wire went towards the label like it was when I removed the pin from the harness connector.
The printer consistently jams after several minutes of running, but everything seems to work (bed leveling, extruder, heated bed, display), just not this fan.
