I replace my Thermostat, when try to test fan On function, the fan is not working? How can I check/test the fan unit, and verify if the fan or the thermostat is bad?

The G wire terminal and Green wire are what controls the fan. Check wiring to be sure all is correct. Post brand and Exact model number.
