Arrma kraton 4s motor fan not working

[Keenan Sykes]

Hi,
About two days ago i pluged the battery into my arrma kraton 4s turned on the radio and car and noticed that only the esc fan was running but the motor fan wasn't. I bought a new fan thinking it was that but it still doesn't work if anyone knows what is going on it will be very helpful.

Does the fan spin freely if you push it by hand? Have you checked that the fan is still plugged in correctly?

Changing the esc doesn't do anything for the motor fan as this usually get it's power from the receiver. Chances are your fan motor is just fried and you'll have to buy a new fan(they are inexpensive luckily).

But first check those things and let us know.

If you have replaced the fan and it still doesn't spin, try another channel on the receiver, if you know your steering servo works the fan should work on that channel aswell, if that still doesn't work then I honestly have no clue what's going on

Could be the servo extension lead as well.. the 4s line has one that follows the motor wires.. it's possible the motor or motor heatsink broke a wire.. worth a look..?
