Hello all. I just purchased my home, so dont know a lot of history behind the AC unit. It is an American Standard Allegiance 10 and appears to be around 13 years old. When I turn the unit on at the thermostat, the blower kicks on, but not the outside unit. Ive done some troubleshooting and came to the conclusion that it is the main board that is not functioning correctly. I will go into details if necessary, but the basics are:
Capacitor is good,
Contactor is good, but not receiving the 24 volts to activate it,
Transformer between the board and the contactor is not receiving any voltage from the board when the unit is running... thus my conclusion that the board may be bad?
Can anyone give me some guidance on if I am correct in my thinking... and let me know of a way I can test the board? I dont want to purchase a non returnable part if thats not the problem. Thanks!
