Nest not turning heat on. 3rd Gen nest runninbg firmware version

[Tenna1dt]

3rd Gen nest running firmware version 6.2-22 will not turn furnace on.  Set at 69, house is 59.  Running fine some days, but randomly works, then doesn't. Factory reset (as recommended by Nest Support) didn't work.  Getting standard "2+ hours" message.  Seems like quite a few customers are experiencing same issue but the concern has yet to be resolved.  Should I replace with an Ecobee?

I am experiencing a the same problem.  In the northeast where I live this is a real issue.

Hi everyone,

Thank you for reaching out and we're sorry for the delay.

Let's try the following for us to further isolate the issue:

• Restart your Nest thermostat.
• Remove the thermostat from the base. Check all the wires are properly inserted.
• Check your HVAC filters and drip pans for clogs.
• After a restart, go to settings > equipment > select the right heat type and source based on your HVAC system.

Let us know how it goes by replying to this thread.

Regards,

Ryan

I have a similar issue. When I use the Gen3, no heat (blower turns on, shows orange/heating on the display). Swap back the Gen2, everything works fine.
