In this video we teach you how to fix Nest Thermostat low battery issues and Nest Thermostat low power issues. There are several things that could cause your Nest Thermostat to have a low battery. Typically Nest low batteries are caused by your HVAC system not putting out enough power, or by an issue with your HVAC system that has cut off the power supply to the Nest Thermostat. A Nest low power issue can also be caused if your Nest has sat in the box for an extended period of time.

To fix Nest Low battery or Nest Low Power issues there are a few common ways to fix the low power issue.
1. The easiest method to fix a nest low power issue is to try charging the Nest using the built in charging port on the back side of the Nest. This will typically work for a Nest Thermostat that has sat in a box to long or the power to your HVAC system has been turned off for an extended period of time.
2. If charging the Nest doesn't work you can then connect a common wire to your HVAC system. Some thermostat wires will have an extra wire run with the thermostat wire that you can connect to the C terminal on the HVAC system and the C terminal on the Nest Thermostat. If you don't have an extra wire you with the thermostat wiring you can add another wire connected from the C terminal on the HVAC system to the Nest Thermostat.
3. If adding a common wire doesn't work your HVAC system is either not compatible or is not putting out enough power to power the Nest Thermostat and a common wire transformer might be needed.

The Nest is disgraceful trash. Even when functioning, the UI and "learning" is brain-dead and incompetent. Even worse, it's an entire computing device that you're supposed to THROW AWAY WHEN THE BATTERY DIES. Unfuckingbelievable. I have a powered (C-wire) thermostat connection, and I had to trash the Nest because the battery died and the aftermarket batteries all have hideous reviews.

Most easiest video I've found to follow for the Nest thermostats. Much clearer than trying to get results from the Nest help line, I did the settings check and found these readings...6.5 and 40I , indicating as you said the battery(s) were low. I did find a USB charger that had the correct end on it and the batteries are charging as I type. let them run for an hour or two and see if that fixes the immediate problem. Thanks for the great video...a grateful friend.... Don

I was having problems through the app while away. The temps have been from low 20’s to single digits (and even a few minus degree days) so I decided to stay with my bf and save my fuel. I check my Nest app regularly when I’m not home to make sure everything is ok @ home. Several times I’ve had one (of 2) thermostats show “offline” in the app. Researched the issue & determined that it was likely a low battery. Thanks for the well done video explanation on how to charge the existing battery. I almost bought a new one on Amazon! Good thing I read reviews & one person said better off recharging rather than replacing. I would have taken my unit apart trying to figure this out. THANK YOU 🙏🏻

@adamre09 Ай бұрын

Having the same issue… power outage triggered both Nest thermostats to start having battery issue. I can charge via phone cable and that will work for a few hours, then the battery dies again. These worked together fine for 5 years and all the sudden BOTH stop working at the exact same time. Idk what the issue is. Voltage and Lin seem fine.

@f.c.9132 7 ай бұрын

Learned tons from your video man! Thank you! Realized I only have a RH and W1 wires connected, no C. Keep losing power and the lin is at 20 which tells me I will likely need a (C) wire if it keeps happening since I have no G. Had no clue what any of this was! So thanks!

Your advice to connect the Nest to a charger while it's off the base was excellent! It's charging right now. I'm troubleshooting why the Nest is dead. I did verify the 24 volts is NOT present at the base. But if I can verify the system works otherwise, then I'll resolve the issue with the 24 volts. How can I determine which generation my Nest is? I think it's Gen II. I want to change the battery simply because the thermostat is more than 5 years old. But, before I buy a new battery, I want to be sure I get the correct one.

The room is rarely used, so I’ve had the system in that room set to OFF. Is this ‘OFF SETTING’ possibly leading to the 2 ‘AAA’ batteries draining, because the thermostat isn’t getting power from the hvac unit?

This video single handedly helped me fix my mother's Nest Learning 2nd gen thermostat when nothing in Google's Nest Troubleshooting site, Nest ProTech Diag pdf, Nest Community forums, or any other Google Search return could. The Event: Heating for past few winter months (NO A/C usage since October 2022). Beautiful day in East Texas, mom turns Nest "Off". Next day, 80°F+ and 95% humidity, mom turns on A/C, and leaves to run a few errands. On arrival home she realizes that it's 78°F in the house. Air Handler blowing air, air not cooled. She calls me, the dutiful son. Nest Learning 2nd Gen display in error mode with message E30 - "No Power Detected for Y1 wire". Y1 is the Air Condenser unit outside of home. In Tech Info menu, it also says that "WiFi Disconnected". Can't get out of error mode other than to view "Wiring Diagram" and the various "Tech Info" submenus. I remove display unit to check wiring, all are fully seated. Wires are Y1 (A/C Condenser), G (Ground), Rc (Cooling Power), W1 (Furnace/Air Handler), Rh (Heating Power). I go outside and manually inspect A/C and it's independent breaker, not on breaker good, flip breaker, still nothing. Go inside reinstall display unit, same message error mode, can't get out of error mode. Left. Today the A/C came on by itself and started blowing cold air. No more error mode. Settings display "No Wifi Connected" and several functions auto disabled. Removed display unit and then it showed "low battery". I think the turning the nest "Off" for a full day drained the battery enough that it just couldn't function and was drawing it's power from the Y1 A/C or W1 Heater, but since we were trying to run the A/C and not the heater it couldn't charge itself to switch the A/C on and since we have no C wire it can't charge itself when neither HVAC systems are running maybe?

I could not find anything about this online 2 years ago and their customer service just send me a new one which plug in and "solved" the issue(only because it's not that hot outside anymore, it's stealing power from the coil again).

I'm getting a E73 code on my Nest 3rd Gen, I blew compressed air through the condensate out line so that seems to be clear. I also checked the voltage on the nest and it said 3.07v which I guess is low. The thermostat wire is brand new, replaced it from furnace to Nest when we installed the nest a couple of months ago.I removed the condensate pump and made sure its empty, later today I will try cleaning it with white vinegar so make sure that there's no slime buildup although I cleaned it a few months ago. Sometimes the furnace will kick on and run for 5 minutes and then kick off and the E73 code shows up again. The thermostat wire is a 5-wire one, Blue is hooked to the "C" terminal, the red wire is hooked to the "Rh" and the other wires, yellow to "Y1" and green to "G" and white to "W". I did the jumper (W1 connected to RC) and the furnace went right on. My furnace has an external bare transformer and is there a way to check if the transformer is flaky?
