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
Thank you for identifying the manufacturing logo and the manufacturers logo identification website link I have an older version of this and not all of them are on it
