AC doesn’t stay on google nest thermostat

[Mtschuman]

 

Heat works fine. AC starts then stops before truly cooling. 4 wires to thermostat. Red to R, white to W, green to G, blue to Y on both the thermostat and furnace control board. I also noticed the nest thermostat was chattering in cool mode. 

Trane xr90 furnace and xb10 for cooling.

Any help would be appreciated.

Hi there,

Thanks for reaching out. A few questions: what type of Nest Thermostat do you have? You can visit this link to check what type of thermostat you have. Also, do you see any messages or code on your thermostat or in the app? 

Best,

Jenelyn
