Hi Guys, This may be a long shot but I am looking for a carrier zephyr 200 1989 model control panel wiring diagram or service manual if there is one...
This unit came to me today not working it is mounted on a trailer and works off 240v single phase.
I don't have power to the controller (display) but I have power to the relay module from the transformer. tis an old one. So before I start tracing the wiring physically I thought I'd ask the oracle's.
