I have had my Nest Thermostat since last winter. Last winter I had no issues after installing a common wire. I had no issues until about a month ago. My nest is heating the house fine. The problem is if i set it at 70 it shuts off once it gets to 70 like it should. Then a short time later, my furnace will come on for like 5-10 seconds then shut back off. I’m not sure why it’s coming on for this short period of time when it’s not necessary.
