Hello again, The unit may be very low on refrigerant and cycling on its low pressure cut out switch. If you can send me a clear, well focused, close up photo of the wiring diagram glued to the inside of the units control box cover.. and a photo of the printed circuit card that shows where the thermostat wires connect I can help you by marking it up with trouble shooting instructions.Use the paper clip icon above to attach those. Tell me please if the outside unit runs in the winter for heatingas well as in the summer for cooling or not. .
