If not check console for error messages - wrong wiring or pins can cause temperature failures that cut off the funczionality and you see it in log why it happens.
Last thing make sure you are not in dry run mode - that also disables all heater functions.
And only write in one categrory not in 6. Will delete the other entries.
Note that heater/sensor 1 is meant for bed and if the board has a dedicated pin for this it points to that pin so heater 2 will then be the one named 1 on board or named 2 if board starts counting with 1 and not with 0.
If you are using Repetier-Host disable easy mode. Then you should see which heater is causing the problem so you see which config options and pins to check.
Also in manual control you just send "M999" as command to restart (or press reset key on printer). Then it resets heater management until problem happens again. But you should only change wires when printer is not connected to anything for a minute.
Can you give me a full ready to upload code which I don't have to modify and just simply upload. If not then please give me a step by step detailed solution because I am kinda noob at it... Please help me!!!
I can say that you should use M119 in host to test if the switches are correctly assigned. So trigger one and send M119 while triggered and see if it shows to be triggered. If not they are configured wrong. But can't say how this is configured in marlin.
Some hotends have a cooling fan that cools the heat break so temperature does not creep up. This needs a fan input that is configured as extruder cooler. Firmware distinguishes between extruder cooler and filament cooler. Filament cooler get controlled by M106/M107 while extruder cooler gets activated automatically when extruder gets hot.
