Heat won’t stay on at night

FreezingTnxNest — Sun, 12 Dec 2021 08:46:49 GMT

I’ve had this thermostat for about 2 month now. I don’t have it on “learning” because it wasnt learning, I don’t have the schedule set up either bc this thing just does whatever the heck it wants to do. I literally have to reset it daily. I wake up freezing every morning bc it won’t keep the heat on unless it’s a 75* day, it’ll blow all day and cooperate to my adjustments. When the 32* nighttime comes, it says it’ll be over 2 hours to heat my house (even when Ive had it set on 72) the temperature just drops, instead of heats. Every time I have tested the heat it does not work, but the heat will work all day long, when the night time comes it’ll come on for less than a minute and then shut back off till about 9 AM the next day or so. I have reset, restarted and removed this thing so many times, I have rewired it, that’s not the issue, I’ve checked the furnace, That’s not the issue either. I have had zero issues with my heating and air until I put this nest thermostat on. What is the problem? Ive done all the troubleshooting every single night for the past two months, it’s getting really irritating freezing every night and messing w this stupid thing. I’m about to rip the **bleep** thing off and throw it back to the **bleep** Google company and go back to the 10 year old thermostat I had on here! @User123456 @Nest @googlenest

At the very least you need to set your minimum temp for eco mode. Smart schedule takes weeks to really start working and is wonky if your family has widely divergent schedules, or your tstat is in a location that doesn't see a lot of traffic. You will have to setup a schedule, it is how it was designed to operate.

I have had my two nest units for over a year and they have worked fine however now I am having the exact same issue with both not heating at night. It seems that the firmware/software upgrade to 6.2.22 may be the issue. I have tried everything to fix it. It is not a hardware issue as I have had the maintenance guy out to check both units and when he puts the old thermostats back on they work fine but when they switch back to the nest I am having this issue with not heating at night. It never seems to reach the temp it is set for. I have them set for 70° and although the thermostat stays orange as if it’s heating the temperature slowly drops and it says 2+ hours to reach 70°. And just continue drop during the night.

Was this ever resolved? I am having the same issue…

I have the same issue, it started on Wednesday, works fine day time but as soon as night gets by it stops heating

I am having this issue!? Please help

I am also having the same issue. I have had my AC company come out and look at it over 5 times already in last two years. Heat does NOT work at night - only during the day.

I have tried scheduled modes, manual modes, disabling Home/Away assist, and everything else I could think of.

I will keep an eye on this thread in case any can help 😔

I too had this issue and someone on another thread suggested to turn off the safety temperature settings and that has worked for me so far. I live in Georgia so that is not as big a deal for me as it would be for someone who lived in a much colder state.

I have also seen in other threads someone suggest that you simply remove the device from your account and then reset it completely, go through all of the settings to reconfigure it as if it were a new installation and finally added back to your account. That seemed to work for some others. If you have not tried either of those I would suggest giving those a try.

Apparently it seems to be some glitch with the software/firmware version 6.2–22 Good luck!

UPDATE 01/13/22 - Stopped working after a few days and went back to initial issue - unfortunately. Back to square one.

Same issue as others. Past few nights heat won’t come on. In the morning I power off/on the furnace and heat kicks on to my set temp.
-Hasn’t been fun considering the midwests current deep freeze…was -6 outside this morning

I was having the same issue. Just turned off the safety temperature settings and that appears to have fixed it.

does Google nest have a trouble ticket or complaint submission form? This is a major issue that I think could be a risk for litigation for google nest if not corrected.

Why has Google not addressed this yet? I live in upstate New York where it frequently gets into the single digits at night, and this is causing a real issue for sleep in my house. If it's not resolved soon, I'm going to be replacing my nest, and won't be going back to it given an obvious lack of support and problem addressing.

EDIT: I've pinged both the Google Nest Help Twitter account and the Made By Google Twitter account about this. Hopefully that gets some eyes on it.

I am having this same issue. We've had no problems with this Nest thermostat for years and suddenly the heat will randomly shut off and not reach the desired set point until I spin the dial back and forth. It's especially bad at night. As another poster mentioned, I'm in the midwest and these sub-zero temps cool our home very quickly. I have two young boys and we have to check them throughout the night to make sure they're properly covered.

I am running 6.2-22. I've reset, changed all settings, turned schedule off, etc. Nothing has worked.

This is a serious bug that Google should address immediately. How can a thermostat not keep a home at the desired temperature which is its only job? Fix please!

I'm having the same problem as well. I have disable all scheduling, all learning, all home/away assist, the only thing that makes sense is what the one user mentioned about people literally not moving in front of the actual thermostat. If I stay up late (it's right outside my office) and pass by it once in a while, I don't notice the problem, but when we all go to bed, it absolutely will not heat the house to the temperature I set it to. I also have 4 temp sensors all over the house, but setting it to those does not solve the problem either. About to put a metronome in front of the **bleep** thing so it senses movement all night and doesn't turn itself off. It's been -10 or lower at night, and this is a **bleep** thermostat, not an AI supercomputer trying to solve global warming. If we set the temperature high, heat the house!

I’m having a similar problem. The heat runs fine from 8pm-9am but during the day it shows orange as if it is heating but nothing is happening. I had reset the scheduling, ran a test (fan and cooling works fine) but no heat will come out during the day. Any advice would be helpful

Follow up to my post regarding heat shutting off during the night, had a HVAC tech out, he cleaned the flame sensor & my furnace has been working fine since. -He didn’t think the nest had anything to do with my issues.

Following - having the same issue. Works fine during the day but drops to 60 degrees at night.

Are you using a common wire?

Re: Heat won’t stay on at night

Nestusername — Sun, 30 Jan 2022 17:26:12 GMT

No I do not but I intentionally purchased the Nest Learning as it says it doesn’t require the C wire

Did you figure it out? My also has same problem, it shows heating on the display, but actually not. After switching back to my old one, heating is good. So there must be something wrong with the nest thermostat itself.

Having the same issue. Anyone know of a fix?
