Does anyone know what the problem may be after I've replaced a bad capacitor, yet ac still is blowing hot air? Prior to turning on the ac, the room temperature was 83 degrees. Rather than cooling the room, after turning on the ac on with a new capacitor, the room temperature raised to 88 degrees in half hour. I let it run for 6 hours to give the capacitor a chance to start, but no luck. What to do?
