Error name: Chamber cooling fan error

Error code: #31839 (CORE One)

How to fix it?

Start by visually inspecting the fans. 

• Ensure the printer is cold and off.
• Locate the chamber cooling fans on the rear of the printer, from the inside.
  
• Check for debris, look for any dust buildup or foreign objects that might be obstructing the fan blades.
• Inspect wiring and connectors, make sure the fan cable is securely connected and shows no signs of damage.
  • Uncover the xBuddy and the xBuddy extension boards by removing six M3x4rT screws. The chamber fans are connected to the FAN1 and FAN2 connectors on the xBuddy extension board.  
    

• • To gain access to the rest of the fan cables, remove the rear sheet metal cover by removing two M3x4rT from inside the printer, and sliding the cover out. 
    

• • You can gain access to each fan by removing the fan-grid. For this, loosen four M3x30 screws to release the fan grid. 
    

Once the checks are complete, you can attempt to test the fan from the printer menu by navigating to LCD Menu -> Control -> Calibrations & Tests -> Fan Test. 

If the fan still does not operate, it may need to be replaced. Do not hesitate to contact our technical support for further assistance.
