Have you installed, purchased, changed anything just befroe the problem? There are a lot of reasons for this, and a common one is DECT phones, new router, any metal work etc., even microwaves.</P> Tue, 07 May 2024 09:52:08 GMT Frustratedddd 2024-05-07T09:52:08Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-thermostat-lights-orange-to-heat-but-doesn-t-turn-on-boiler/m-p/617812#M119583 <P>I’ve had this issue for a week or so now whereby I noticed the boiler just isn’t turning on in the morning despite the schedule not changing. The thermostat lights up orange as if it’s heating, but no boiler activity. I’ve tried restarting (not resetting) the heat link and that does get it working immediately, however after a few hours it stops working again. Any help or advice appreciated!</P> Sun, 05 May 2024 06:45:15 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-thermostat-lights-orange-to-heat-but-doesn-t-turn-on-boiler/m-p/617812#M119583 Willritchie11 2024-05-05T06:45:15Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-thermostat-lights-orange-to-heat-but-doesn-t-turn-on-boiler/m-p/618143#M119643 <P>Sounds like interference from something.
