The transformer was changed out on the air handler. The Trane air handler is a 4TEE3F1B1000A. I'm not convinced the transformer was wired properly based on past experiences with the contractor.

The wires from the air handler are:

Red
"second" red
white
Blue - which appears to be a ground

The wires from the transformer are:

White
Red
Black
Black with red stripe
Orange - which is not connected to anything

Can anyone tell me the correct wiring so I can check it. I appreciate any help, and thanks.

Is the unit running?

Replacing a transformer is HVAC 101, two wires for the primary side and two for the secondary. Would need to know where the wires come from and go to to answer your question.

Can you post a pic?
