Trance AC, inside blower works outside fan not!!

My outside fan quit working last night. I already replaced the capacitor and now I can hear the compressor click on and the fan humming but it will not turn on. It spins freely with the stick, but will not catch and run on it's own. Please help 85 degrees inside now and supposed to get to 100 today!

If the replacement capacitor is good and the capacitor & fan are wired correctly, perhaps the fan motor burned out. If you have a multimeter, you can check for voltage across the fan wires and (if the voltage is OK), you can turn off the power, disconnect the fan wires and check the resistance of the fan windings.

Thank you. I took a look at the wiring diagram and turned the capacitor around plugged it back in and "stick" started the fan. House is cooling now, we will see what happens once it turns off at the thermostat temp.

Ok I am back to needing help again. Finally reached my temperature and everything shut off. Lowered the t-stat and everything came back on but the fan. Had to stick start it again! Guess I'm gonna need that fan motor after all right??

Usually, if the fan will run with a "stick start", it's a sign that the fan capacitor is bad. If the motor windings or bearings were bad, it wouldn't run at all. I would suggest that you either bring the capacitor you purchased (I'm assuming it's new) back to where you bought it and ask them to either test or replace it, or purchase another one. I don't know if you purchased an US made capacitor or a Chinese one. I've heard that some of the Chinese caps are low quality, and it's not inconceivable that it could be defective.
