On many units there is a built in time delay that does not allow the compressor to start iinstantly.

This delay allows the gas pressure to unload , so the starting amps do not go thru the roof.

I believe it might be a faulty High Pressure switch. Check the switch after the compressor has stopped. If it is open, The switch has tripped. The switch range should be marked on it. It would then be necessary to check the High side Pressure to determine if it is going off on high pressure or if the switch is faulty. When checking the high pressure it should be within the range of the High pressure switch.
Just My nickel..... (inflation you know.....)

I have a split system like this (Crusair) from 1982 or so. It was only giving heat so I disconnected the reversing valve till I got around to replacing this controller for about 80 bucks. My schematic was under the access panel. 30 years old and still chillin!

They are good units. And easy to work on and service.

Update for psneeld

I just checked my rotary dial for the thermostat that I mentioned earlier in the post and the access hole is in the REAR of the switch. Not the front see pic.

The forum at marine-ac.com has a good discussion of issues encountered with these older units...

The pullout from my old cruisair has this as well. Might have fixed my issue but I figured it was on borrowed time at 30 years old. Note Mine was pop riveted in and I have to pop rivet the new one in as well because when I tried to use screws the screw head interfered with the knob.
