The cooler fan is the fan in charge of keeping the hotend area prior to the heater block cold to prevent the filament from melting before reaching the nozzle and clogging the hotend. Keeping the fan clean is vital to maintain the life of the fan and ensure good cooling of the hotend.
To clean the fan, do the following:
1. Turn off and unplug the printer
2. Using the pliers, remove any visible filament remain from the fan.
3. If the fan has dust you can use a vacuum cleaner or compressed air to remove it.
It is recommended to clean the cooler fans every 300 printing hours.
