At this point there could be a couple different things causing your condenser to continue to run. Most likely a stuck or shorted contactor is the culprit. The contactor when energized is what powers your condensing unit to run. If they become stuck or shorted closed, they will cause your condensing unit to continue to run when they are not susposed to. A couple other things that could be causing this are a shorted thermostat wire or bad thermostat. The breaker to your condensing unit or package unit should be turned off and a service technician should be called to troubleshoot your system.
