Many outside AC units have just one capacitor that starts the compressor and the fan. Some units however have two. Just follow the wires from the motor to the capacitor, pull it and test it. Make sure you disconnect the power from the unit by pulling the fuse block first. If the capacitor is good the motor may have siezed up or burned out.

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.
1. common
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

Armstrong concept 1200-bad start/run capacitor?

Yes, most likely the start capacitor has failed & should be replaced. You have proven this by being able to hand-start the fan. Once replaced, the compressor should kick in & work fine.

On 12 year old AC fan works, but there is a periodic muted buzz but compressor doesn't engage.

The hum is generally attributed to the compressor trying to start- being intermittent suggests it is failing and going into a delay via an internal safety switch. Assuming this and the fan you speak of is the condenser fan there are 2 good diagnoses- either the run capacitor is bad or the compressor is locked up. I would change the capacitor and install a hard-start capacitor, if the problem persists it would most likely require a new compressor.

I have a 5,200 BTU Maytag window AC. The fan will not start when turned on. The motor hums but will not turn. I lubricated the bearing so it will turn very easy. Is there a starting capacitor for that...

The motor could have or not have a capacitor. You will be able to know if you can look at the wiring diagram which will be on the unit under the case, or disassembling the electrical compartement. The capacitor will more than likely be in the electrical compartment. It will look like a battery, and will probably be a 3 post capacitor. The fan will be connected to "common" and "fan".

To check the capacitor you will need an ohm meter. Unwire the capacitor on the fan and common terminals, marking where the wires go before you pull them off. Take the leads of the ohm meter, turn the meter to its highest ohm setting and touch the two posts with the leads. If the capacitor is good, the needle of the ohm meter will jump up, and then back down. If the ohm meter does nothing the capacitor is open, if the ohm meter needle jumps all the way over and doesn't come back down, it is shorted.

The compressor on my ac unit at home is not working. I can hear the motor on compressor running but the fan is not moving..ideas?

Replace the condenser fan and capacitor on the unit. The capacitor is the starting component for the fan.

I have an Armstrong Air Concept 1000 AC unit won't turn on

Neither of the above solutions are correct. You need to replace the capacitor 35/5 uhf 370 vac the cost should be $15 or less at a local HVAC retailer. Make sure you have the breakers off plus pull the contacts out which are inside the big box connected to your house. Make sure you pay attention to where the wires go. The red wire goes to common, the yellow to compressor (herm) brownish to the fan. The capacitor will be oval not round <!-- from fixya rte -->

Fan motor will not come on

That thing connected to the capacitor is a booster for the compressor .But if the outside fan doesn't work , the compressor will shutt off on overload because the high pressure in the condenser coil.
First try to replace the capacitor in the condensing unit (it's the only one that works for the compressor and the fan motor) ,but if the fan doesn't start, you need to replace the fan motor.
