Two days ago my outdoor unit quit blowing cold air. The first thing i did was change the capacitor. Replaced it with the turbo200x uni-cap as this was the previous one installed. Got everything hooked up, cranked it up and found out the fan motor was bad. Went and picked up the motor and the guys in the shop gave me a single cap for just the motor. Fan is working fine now. The current problem is that compresser is just making a slight buzz. Found this out by unplugging the fan for a sec so i could hear the compressor. As long as the thermostat is on, the compresser is just buzzing. What is the deal here? Any help is greatly Appreciated .
