Nest Thermostat Not Cooling

Community Member

They’ve checked the unit and system it is working properly.  No problem w freeon.  It’s only 3 years old.  The Nest continues to display in 2+hours.  
Checked the wires, reset the system back to factory setting, checked for updates. Any other suggestions.

Thanks for reaching out and for being a step ahead of us. Could you please take a photo of your Nest Thermostat wiring diagram by going to your thermostat Settings then Equipment? Also, provide your thermostat power readout.


You can follow this guide:


  1. Go to your thermostat Quick View menu.
  2. Go to Settings.
  3. Look for Technical Info.
  4. Select Power.

Please help! It randomly stopped cooling yesterday and it is too hot. It has been stuck on cooling for 2+ hours for over a day and it has just been getting hotter. 
Battery 3.886v

voc 34.38 v

vin 34.38 v

lin 200 mA (c)

Just to reiterate there is been no issues at all and the thermostat as well as the AC unit we’re both newly installed August 2022 and it does have the c wire installed

Hi Konnerrgarrett,


Thanks for letting us know. Based on the power readout you shared, they look perfectly fine. Please try to restart your thermostat by going to the Settings > Reset > Restart. After that, check your thermostat power readout to see if there will be any changes. If there is, check for any codes or messages. 


Checking your thermostat Energy History might help to see what your thermostat was doing previously. You can visit this support article on how to check Energy History in the thermostat or in the Nest app.


Also, see if the utility company installed an energy savings box on your HVAC system.


Best regards,

I have the same problem. Did you find a resolution?

Hello everyone,

I'm chiming in to ensure that everything is covered here.

I appreciate you looking into this, Jenelyn.

@Michelle888, thanks for posting on this thread, and I'm sorry to hear you're having the same issue. "In 2+ Hours" generally requires no action on your part as it's an estimate time to reach the desired temperature settings. If this message takes longer than expected, there could be a potential problem with the power itself. Does your Nest Thermostat have a C-wire installed? If there are none, please take a look at this article to learn more about how it works and how it helps your thermostat avoid power issues. This also applies to your Nest Thermostat, @BBM.


Let us know if you have more questions.

Best regards,

Thanks for the response. It does not have a c-wire. I didn’t install it though it was here when we bought the house.

I noticed it works in the mornings and usually evenings but not during the hottest parts of the day.. so is this a power issue?

Hey Michelle888,


Thanks for the update. Some utilities install boxes to cut off power during high demand (peak) times. Check for one of these boxes on your line.


Here’s how to see if you have an energy savings box:


  1. Check your meter (possibly near your air conditioner).
  2. Look for a small box with one or 2 lights on it (one light is red, the other is usually green).
  3. This box allows the utility company control to cycle your air conditioner off and on during certain peak times of the day.


I appreciate the help, Mark.
