Can you measure the size of the mosfet?

I am not sure if they are mosfet, because the part number does not match other mosfet part numbers from that company. They use "N" between the numbers instead of "R".

If those are mosfet they are probably 600V 16A. Maybe you can replace with one with the same or greater parameters and check if its work.

An example: STW25NM60ND
