AC Blower Does Not Come On

(Gunter TX)
Question: I have 2004 keystone ac stoped working found bad breaker and replaced still does not work,compressor comes on ,blower does not, so i replaced starting copassitor still nothing. could the problem be thermotsat?
Robbie: I would check and see if you have voltage to the motor. If you do then you need to replace the motor. If you do not have voltage then you need to go to the switch. If your AC unit is operated through a computer circuit board you need to check the connections to the fan at the board. They may be burnt and you'll need a new circuit board.
The start capacitor does not operate the motor but supplies the extra surge of voltage needed to start the compressor.
