My nest thermostat has been working fine for almost 1.5 years but suddenly stop heating. In some occasion I am able to get the heat working by turning the dial all the way down or off and then after sometime turning the heat back on up. I set the temperature to 71 degrees, thermostat changes color to orange, start heating and after some minutes stops heating.
Nothing in the wiring or configuration has changed.
My product is Google Nest Learning Thermostat.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
