MKS BASE 1.4 Dead MOSFET and solutions

Dear all good day to you.

Today It seems i managed to cook the MOSFET controlling my part cooling fan through fault of my own.

The LED stays on permanently and the FAN is always on irrespective of the command I send.

I wanted to ask how, within the Marlin firmware, I am able to set the part cooling fan to output via E1, as this is spare on my board.

My board is a MKS BASE 1.4 with picture attached for reference.

Otherwise, based on the above information, would desouldering the MOSFET and soldering a fresh on cure my problem?

Many many thanks for your help

I would say that if you have the ability too replace the mosfet, that as a technician the mosfet replacement would most likely fix your controller cards fan circuit.
