I have a GE AEM24DT Air conditioning unit which I use to cool a cheese aging room. To make the air conditioner run cooler, it is controlled by a coolbot, which was designed to do just that. I have the system set to keep the room at 52 Fahrenheit and it works great. (The coolbot is designed to keep a room as low as 34 F using only a air conditioner.) However, I would like the fan to shut off when the compressor in the air conditioner is off. I would like to cut down on the airflow in the cheese aging room. Anybody out there who could help me with this?
Thank you very much.

The fan appears to be speed controlled via the 3 wires , BL,YW,BK.
You could use a 3 pole, mains coil relay to switch these 3 lines.
Connect the relay coil across the BL, YW wires connected to the compressor.

When the compressor is OFF the 3 pole relay contacts will be Open.

Choose a relay to suit your local mains voltage.
