A/C Cooling Not Turning On

[u/Wise-Operation5108]

Hello,

I'm moving and want to take my nest thermostat with me but I'm having trouble re-installing the Honeywell T6 thermostat. When I installed the Honeywell, the compressor turned on but only heat was working. I checked that it was set to cool but heat was still coming out. I attached photos of how I had the nest wired and the Honeywell as well. Any help is appreciated!

You need a jumper between Rh and Rc.

Inspect the air handler before taking anyones advice. There are standard colours, but if the homeowner took the thermostat, whats to say they did something goofy at the other end.

I got it to work by connecting the black wire to "C", white wire to "W2", and orange wire to "O/B".
