Nest Thermostat Blows warm air during day, cools great at night

rangellalo1 — Wed, 07 Jun 2023 02:17:48 GMT

During the day, the AC blows warm air as if the fan was blowing but not the compressor. The thermostat says 2 hours+. At night, around 8 pm, it starts blowing cold air. When I change the time on the thermostat, the AC blows cold air until the thermostat syncs up via the wifi. Every time I change the time to evening time the ac cools.

Any ideas?

This sounds like you have a Cool Schedule that is active. Check the cool schedule.

Thanks. I have deleted the entire cooling schedule and reset. But the same. I’ll recheck and see.

Go into your Thermostat setting in the App, and turn off Auto schedule, As well.

@rangellalo1 , out of curiosity, what is the white wire in the * connector controlling?

OK, let me see if I understand your original message. You say that during the day, the Blower Fan comes on, but the outdoor compressor does not turn on?

I am not sure. I know that everything was working fine until a few weeks ago when some chipmunks ate through the wires. The AC tech repaired the wires, and all was good. This happened a second time, and he repaired them again. Then I started having the issues.

Do yourself a favor, have a new thermostat cable pulled though and conduit till it get inside your home. That will keep the critters away.
