Many printers, especially those in the Ender 3 series, have fans that help to keep the components from overheating.
Unfortunately, sometimes something could go wrong and your ender 3 part cooling fan might not be working properly.
Various solutions are available, and you can explore different methods in this article to fix this problem.
What happens if the Ender 3 part cooling fan stops working?
If your 3D Ender 3 printer’s part cooling fan stops working, it can have a major impact on the accuracy and detail of your 3D prints.
Without a functioning part cooling fan, your filament has less time to cool down before the next layer is extruded on top.
This leads to warping and misalignment of layers – an effect that becomes increasingly worse as the print progresses and you end up with an inaccurate and failed final product.
To ensure better performance, always make sure that your part cooling fans are running properly and replace them if necessary.
Steps to fix Ender 3-part cooling fan not working:
If your Ender 3-part cooling fan isn’t working, don’t panic – a few simple steps will quickly help you troubleshoot the issue and get it up and running again.
- First, make sure the fan is properly connected to the correct pins on your board.
- Check the wiring harness for any breaks or damage.
- If everything looks good but the fan still won’t power on, try swapping out any suspected failing components on your mainboard for new ones.
- Replace the PWN driver with a new one and check your mosfet for shorts or opens.
- Make sure to double-check all cabling connections when replacing parts and go slow – careful diagnostics are key!
When to replace Ender 3-part cooling fan?
Replacing the part cooling fan in your Ender 3 can be a last resort and tedious way to get it working again, these days.
After all the various troubleshooting steps have been exhausted, it may seem like an endless process with no end in sight.
However, by ensuring the correct replacement part is found and any new components are within spec of the original ones, you can be certain that you will finally have your Ender 3’s fan working as normal once again.
