Try to disconnect the supply from circuit breaker for 10sec. and "on" again, if it doesn't work you need at qualified technician for that problem.

The things that you can check yourself are
is the indoor unit level?
Are the filters clean?
The area the water is draining to free of obstruction?
Is the drain actually draining?
----Get a cup of water and pour it over the indoor coil (please make sure the power is off first please) If the water does drain then it is prolly a bigger problem.
Prolly your unit is short of gas and need a refrigeration tech out to check. That it isnt ice-ing up but you would notice the performance drop.
Hope this helps

OK, now we need to let the comopressor cool down if it is hot. Once it is cool, (that could take a while if it is so hot it tripped out on internal overload.) check for continuity between the compressor leads. If they show continuity between them hook the wires back up and turn it on, Check the amp draw at start up, and check the voltage to the compressor.
The compressor is bad If....
1) there is no continuity between the compressor leads.
2) if you have an amp draw but the compressor is still not pumping refridgerant.
If you do niot have voltage going to the compressor, then we will need to trace down the cuase for loss of power.
