Err: PRINT FAN ERROR

Updated 6 months ago ​by Tomáš Chvalina

PRINT FAN ERROR error message occurs when the extruder fan does not receive any RPM (Revolutions per Minute) readings, in other words, there is something preventing it from spinning.  

Troubleshooting

  1. Visually inspect the print fan and make sure there is no debris preventing it from spinning.
  2. Bigger parts can be cleared with tweezers, dust can be cleared with a computer cleaner spray (hold the fan with your hand while blowing at it, otherwise, you might damage the blades).
  3. If you have replaced one of the fans with a replacement part not supporting RPM sensing, then you can turn off the monitoring in the LCD Menu - Settings - Check fans.
  4. If the print fan just stopped working completely, it must be replaced. You can purchase a new one at our e-shop or contact the support.
