Tried switching the heat pump to cool for the first time this season to find that the Nest thermostat activates Y1, G, but not O which is required to activate cooling mode on the heat pump. Nothing has been changed since last summer when the AC worked.
I tried resetting the thermostat and doing the setup again, and in test mode it(and normal cooling mode) it is only giving power to G and Y1 and not O/B.

Hi Demaize, thanks for the reply. That's how I currently have my thermostat wired. Again, nothing has changed for the past 1.5 years when heat and cooling worked appropriately.

Hi there,
Chiming in — could you please provide your Nest Thermostat power readout? It will help us to move forward. Also, do you see any messages or code on your thermostat screen?
I appreciate your help, @DMaize and Zoe.
Best,
