There are no lights on the heatlink ive checked and voltage is going to it. Nothing happens when i try to reset the heat link. I can see this is a common problem. Could someone send a replacement heat link?</P> Mon, 20 Dec 2021 17:22:56 GMT https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-3rd-Gen-Heat-Link-no-lights-even-though-voltage-is-present/m-p/67129#M15254 luigibeats 2021-12-20T17:22:56Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Nest-3rd-Gen-Heat-Link-no-lights-even-though-voltage-is-present/m-p/67200#M15265 <P>I'm having the same issue.
