It’s set to 68 but my house was 59. &nbsp;This has been an on and off issue since we started the furnace. I need to manually turn off the furnace and switch it back on and then the house starts to heat. &nbsp;I’m just about ready to trash the nest and move to another model, any suggestions?</P> Fri, 14 Jan 2022 13:11:29 GMT Shermanov 2022-01-14T13:11:29Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Heat-won-t-turn-on-again/m-p/83410#M18595 <P>Woke up again to a freezing house. &nbsp;It’s like my thermostat has a mind of its own.
