I have a folger tech i3 prusa 3d printer, and it was working properly until after a print, then I started to get the hot end temperature readings for bto the hot end and the heated bed. So when I heated the bed nothing would happen. But when I heated the hot end both temperature readings started to rise. The thermistors are in good shape and after switching connections I realized that the T1 connection on my 2560 board is the one misfunctioning. I have been messing with the firmware configuration.h file but I can't get itbto work. Any suggestions?

Go to pins h file and switch the pins from T2 to become the new T1, unless you are using dual extruder.

Do you think you could show me where in the code that is located? I took a look at it but I could barely understand it.

in latest marlin [github.com]

ie in the file pins_RAMPS_14.h

#define TEMP_0_PIN 13 // ANALOG NUMBERING
#define TEMP_1_PIN 15 // ANALOG NUMBERING

and a bit lower down

#define TEMP_BED_PIN 14 // ANALOG NUMBERING

t0 is pin 13
t1 is pin 14
t2 is pin 15

Just swap these as needed..

ie to swap t1 and t2 change the following
#define TEMP_1_PIN 14 // ANALOG NUMBERING
#define TEMP_BED_PIN 15 // ANALOG NUMBERING
