A/C comps. rarely go bad. However, when the A/C is on and you're sure the pump is turning, (look at the pump and be sure the center where the belt goes around it is spinning too) if it's making a grinding noise or freezes up it's bad.

P.S. : The temperature when changed on the main panel will directly change the pressure of your compressor which will affect the room temperature.
