Stage 1 Cooling Disappeared

[tjs198]

I have a 2 stage heat pump with electric coil backup heat.  Installed nest 3rd Gen tstat yesterday, everything seemed fine.  Today, stage 1 Cooling seems to have disappeared.  Unit only cools with stage 2 and even under settings - equipment - test: stage 1 Cooling test dissappeared (was there yesterday).  Any ideas?

Hi tjs198,

Thanks for posting in the Google Nest Community forum. Could you please send us the photo of your Nest Learning Thermostat wiring? It will help us to move forward. 

Also, check if your yellow wire is connected directly to your system's control board. You can also try to reinsert your AC wire to your thermostat. Ensure that your power breaker is off before touching the wires. 

Best,

Jenelyn
