OK but the circuit Dougy83 is proposing is for a DC motor.Dougy83
Please describe 1, 2, 3, 4 in attached jpg. I apologize, trying to understand.
I looked into using a garage door opener with a micromatic delay on relay and the cost for the two is about $200. I received a bin of garage door motors for free and hoped to make the circuit board less expensive since I have access to the electronic components.
Your AC is going to need a start cap and special switching to work.
Start buy looking up some of the garage door opener wiring diagrams online to see how they are hooked up.
How many wires do your motors have coming out of them?
