After I disconnect compressor wire,unit operation only indoor but unit still trip at ELCB...

Just a few more details if you can. Be as specific as possible. Got the fact the breaker is tripping. Let us know what you have done us until now.

Now I just disconect waterpump wire,compressor wire at indoor and now running only indoor... but still trip at ELCB

I`m from WV.. I`ve never seen s split system ac with a waterpump,, must be a groundwater system,, help him thermalmedics

Sorry, I'm stumped too. Maybe a swamp cooler n a/c combo jober.

Going to need a lot more detail and written in clear English (not that I should complain).
