My heat works perfectly, but the AC does not kick on at the unit outside. The maintenance tech here confirmed the AC works properly as he forced it to turn on outside and it worked perfectly. It seems my wiring for the AC is wrong somehow and I’m pulling my hair trying to figure out what is wrong. Any experts able to share their thoughts on what my might be wrong?
Fuse on control panel is good, AC unit works when turned on manually from the unit, no tripped breakers.
Pictures attached to show my wiring. All wires going into the C-wire Adapter are coming from the Thermostat except for the red Y wire, which is coming from the AC unit outside. The white wire coming from outside is attached to the C portion on the control panel and The green wire from outside is unused.
The cable from the Thermostat also has a blue and brown wire that are both unused and not attached to either the thermostat nor the control panel or adapter.
I tried swapping the red Y wire from outside and put it on the control panel instead and moved the yellow Y wire from the Thermostat onto the C-Adapter, but then the thermostat would not turn on altogether, so I put it back how it was.
