My condenser fan runs and blows cool air but isnt cooling down the house. Any help.
Check the outdoor unit (condensing unit). Keep in mind, because the condenser fan is running it's not an indication that the compressor is working. On a split system,there's a dual capacitor that serves the fan and the compressor. The capacitor has three terminals.
2. fan = fan
3. Herm = compressor
This is a common problem; The outdoor fan (condenser fan) runs, but not the compressor (you have to know the sound of a running compressor or you'll mistake it for the sound of the fan) doesn't, because the compressor side of the capacitor is too weak to give it that needed phase angle that it requires to start. If you're referring to the outdoor fan spinning, but no cooling, I can bet the compressor isn't working and needs a new capacitor. Very common problem, I see it all the time. Before you change the capacitor, make sure that you cut the power to the unit, and then use an insulated tool such as a screwdriver and short the terminals together first. A capacitor holds a charge even after being de -energized.Buy the new one with the same exact rating written on it as the old one. Do not mix up the wires when replacing. Write it down or take a picture with your phone
