My best has worked great for two years. I even replaced my hvac system about a year ago and it synced up and worked from day one. After heating my house for the first time this year I came home and the nest doesn’t even have heat mode. I’ve checked the wires and they look brand new. I factory reset the unit and still no heat mode?!?

Hi Mitchlesco,
Uh-oh! I'm sorry to hear that your thermostat has suddenly lost its heat mode. Please try to disconnect, then reconnect the W or W1 wire, and then check if the heat mode will get back on the thermostat mode lists.
Keep us posted.
Best,
Zoe
