I am at a complete loss as to what to do here. I have a Nest Learning Thermostat that has been in my home and functioning properly for the past 3 years. Out of no where today I got an E105 error and the A/C will not come on and the heat is blowing non-stop. I have attached pictures so you can see what I am seeing here. I have rewired all wires and made sure they are sitting in there spots snuggly. Has anyone else had this issue and what was the fix to make it all work normally again?
Thank you in advance
