Expert:  Daniel Plourde replied 6 months ago.

hi i am dan and i can help you with this. i have seen this problem many times the most common problem is when there is a power outage or surge the capacitor in the outdoor unit will usually blow. if you turn the power off to the outdoor unit and open the electrical panel we can check that.
