Marine Air diagnostic help needed.

[partgypsy]

I have circa 1977 Marine Air split units. Everything works except the compressor does not kick in. One or more of the wires at the control unit (3 rotary knobs) seems to be disconnected. Is there a diagram available?

The other unit works fine except the fan at the evaporator rattles something awful. If it's a bearing, should I just install a new fan and if so, where can they be found?

Thanks

You need to contact the Marine Air manufacturer, now Dometic, or get a service tech to come and look at it.

If everything else runs I would look at the start capacitor on the Marine -Air unit. It's a cheap part and a common failure.
