Diagnostic/ Indoor fan not coming on. I arrived and inspected the indoor wiring. I found that I was not getting the correct low voltage signal from thermostat to allow the blower motor to turn on. I jumped G to Y and got the indoor fan to run whenever there is a call for cool at the condenser. The system is cooling properly at this time, and I will return to install a new thermostat and perform maintenance. Thank you for your business. Bainbridge GA
