I have a Nest learning thermostat that seems to be acting up and not shutting the heat off despite reaching the temperature set point. This issue happens randomly but always in the middle of the night which results in some unwelcomed sweaty wake ups. I usually just shut the furnace off and on again and it's fine but lately the issue has been happening more frequently and the on/off switch trick doesn't seem to fix it.
I've attached a few pics of the existing wiring on the Nest and my furnace (note the orange wire on the Nest is unconnected).
Any help would be greatly appreicated it!
