ac unit- ac won't turn off unless unplugged

Well, that's basically it...I've had the ac running for a few hours, and when I press the "Fan only" button, the ac still runs. When I hit the "OFF" button, the fan turns off, and the ac still hums, so I have to unplug the whole thing...

Its Whirlpool wall unit. Any ideas why this would happen?

It`s your selector switch. I`ve had to replace dozens of them. Write down the model# and serial# number & how many buttons it has. Your local supply house can either get an exact replacement or a universal switch that will work.
