AC not cooling

AC not cooling, looks like only the fan is turning on, heat works fine, any idea ?

I would say a couple of items.

  1. Make sure the cool.is set to AC and not ON

  2. Make sure your Freon is topped off on your AC unit. That bit me today.

On the air handler side, I only see wires from the C and Y terminals to the Wyze adapter. Before you connected the adapter, there should have been wires (probably white and red) connected to C and Y terminals that go out to your A/C unit.

Do you have pictures of the air handler unit before you connected the adapter? Are there by any chance a pair of red and white wires that are now unconnected close to that terminal?
