Hello, everyone

I am looking for the shematic for a/c outside unit it's a trane xe900 the shematic that I need its for the contactor . Please if anyone can tell me where to get it would be great I connected a line wrong and would like to make sure its connected right

There should be one on the back side of the access door on the unit. Every one has one.

Your right there should be one but there isn't one in back of the panel.
Thank you hvac1000 I have been trying to look for it online but maybe I am not looking for it in the right places

I do not have one in my books. Actually it is very simple. Low voltage to the coil. High voltage feed to the from disconnect to one side of the contactor and the other side goes to the compressor and fan.

One of these will work.

Hey hvac1000 thank you so much for your feed back I understand what your telling me yes its easy to follow but there is so many wires running to the contactor I have seen what's low and what's high but its just I want to make sure its correct this is unit is very old I just want to make sure but thank you so much for your quick respones
