It operated absolutely fine, however in the last two months it has intermittently stopped switching the heating off. I reset it and it started working, taking more and more resets. Now however even when I reset it, it continues to heat the house even when it is beyond the temperature or the thermostat is switched to off.</P> Sun, 16 Mar 2025 12:35:34 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-has-stopped-turning-heating-off/m-p/702017#M133551 Mikemont17 2025-03-16T12:35:34Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-has-stopped-turning-heating-off/m-p/705653#M133605 <P>Hi&nbsp;<a href="https://www.googlenestcommunity.com/t5/user/viewprofilepage/user-id/693378">@Mikemont17</a>,</P> <P>&nbsp;</P> <P>Thank you for posting in the community.
