Fan never turns off on my Nest Thermostat. Even if I turn off the thermostat or take the thermostat off the wall. Any suggestions. BTW it does Cool and turns on/off compressor correctly/
Double check your wiring. Are you sure you have a wire properly connected to G? When the fan runs, if you switch off your furnace and back on, does the fan continue to run?
You need to check the wiring carefully. A short between the R and G wires will make the fan run continuously. Even with the thermostat removed.
Chris3, could you please also upload a picture of your wiring when you get a chance?
