AC won't turn on but furnace blower will

I need a hand diagnosing the issue causing my AC not to turn on. My AC won't turn on but the furnace blower is running. I have a Carrier furnace and an Optima 2-s AC

I've checked that the thermostat is turned to cool and set to a low temp. I've checked all the breakers and service shut offs. The power on the furnace control board is 26VAC between COM and Y. So I have a feeling it is something within the AC unit itself.

It looks like thermostat is telling the furnace to cool so it relays the message to the air conditioner but it is not turning on. What should I check next?

Open the panel to your camera and inspect for a swollen capacitor...
