I don't have a diagram, but maybe I can help you. You have 2 compressors, o.k. 2 stage system. A single phase contactor? do you mean a single pole, one side breaks, the other is always hot? Speaking of phases, is this a commercial unit with 3 phase? Also, Each compressor needs a separate contactor to carry the load. What is the question?

I'm not sure exactly what unit you have and what controls you have installed on the unit. But....there usually is a flash code schematic on the unit. Usually on the inside of the blower compartment cover. This should tell you what is wrong with the unit. It could have a low voltage short somewhere and is loosing the call for cool. So the answer can be a possible yes to your question but without knowing the flash code, it's hard to tell from my point of view. You might end up calling a service professional out to check it.

I believe this code is for the outdoor coil sensor not reading or out of range. Check the sensor in the outside unit to see if on of the wires broke or came off it should be located in the outside unit on one of the copper lines near the bottom. If you look through the grill on the outside unit you should see it.

Look on the back of the panel where the green light is located. You will need to remove the bottom panel of the furnace and on the back of the panel you removed there should be a breakdown of the codes as to what the flashing green lights mean. If the code list isn't there you should be able to obtain the code list online if not try to call a a/c company to see if they have a code list .
Good luck hope this helped you

5 flashing is ' compressor drive' and check the high pressure, condenser fan motor capacitor for proper running
