Print cooling fan not turning on

Hi, I just assembled the MK2S kit but the front fan won't turn on during the self test.

I checked the polarity and it's all connected correctly. I also tried unplugging and reconnecting a couple of times but the fan still won't turn. The wires don't look damaged either. Anyone know what the issue could be?

Cheers.

Answer this question I have this problem too

Is this a good question?

Hi Nathaniel,

try to open the RAMBo enclosure and swap the fans. Run the self-test and see, which fan is working (note you've swapped them). If the front print fan isn't working even in the position of the hotend fan, then it is faulty. If the fan works, then the connector on the RAMBo board might be broken.
