Defrost turns on when in the cooling mode

I have a 3-ton Bryant 664A, and the system seems to reverse when it is supposed to be cooling. It will start out cooling well (intake is about 86 degrees, output is about 79 degrees), then I hear the system reverse, and the output is hotter than the intake (by a few degrees).
