Shutoff Messages

Over the past several weeks, I’ve received an email from Nest on 3 days, stating that I have a “potentially urgent” heating system issue. Specifically, my heating system failed to heat my home, as indicated by the fact that it “should” have become warmer while the heat was on for several hours overnight; instead, the temperature in the house dropped several degrees. The suggested causes are an open window or door, or a faulty flame sensor or fan (whatever that means). 

Today, no email; instead, there are only messages on the Nest app: the first is time-stamped at 7:40 a.m., and states that it was “below your safety temperature” (“below 4 degrees,” which has to mean 4 degrees below the setting, because the outdoor temperature was >20 degrees). Then, there’s a message at 9:25 a.m., stating that the temperature is “back to normal”. Finally, the third message is also sent at 9:25 a.m., but it’s the same as the first, i.e., it’s “4 below,” which is below my safety temperature.

The big problem is that I’m away for an extended period, so it’s challenging to get an HVAC contractor in. However, in late October, before leaving, I had an HVAC inspection and service, and everything checked out. 

So how do these sporadic email messages, as well as today’s simultaneous but contradictory app messages, make any sense? Does anyone have any thoughts, explanation, etc.? Thanks in advance.

I realize this is the community support, and not corporate support, but…hello? No one has any ideas?

I don't have an answer, but have been Googling the exact same scenario.  We have a cabin that we're not at much in the winter.  I keep getting the "It was below 4 degrees" message a couple times a day.  Like you've said, it's over 4 degrees outside, so I know it's not really that temp.  Hoping it just means it's below set temp - 4 degrees.  Would like to figure out why it's waiting so long to kick on as I really don't want frozen pipes...

Hello folks,


I'm sorry for the late reply. I understand your concerns regarding the notifications and messages you have received about your heating system. I understand the frustration and inconvenience this situation has caused, especially while you are away for an extended period.

The Thermostat Safety Temperatures article might help to ensure that your pipes won't freeze or your home won't overheat. In the meantime, I suggest checking the physical conditions of your residence remotely, if possible, to rule out any potential issues like open windows or doors. Additionally, if you have any trusted contacts nearby, they may be able to assist in verifying the status of your heating system.

Let us know if you have more questions.

Best Regards,
Mark
