Repair Amana central air unit

Hi,
I have an Amana erh030-w01b (I can't find any reference to this unit anywhere. It's at least 9 years old. Exactly how old .... I don't know.) which only hums when I turn it on (via the thermostat). The fan can be moved easily, so I don't think the motor is burned out. Any help, wrt to fixing this unit, would be appreciated.
Thanks,
..... john

Do some Internet searches; then call a Tech.

Hi All,
I just discovered that I had the model number of the unit wrong. It should have been ERHQ30-W01B.
Still looking for help on how to fix this thing.

check the breaker and outdoor disconnect for power and make sure they are on.

Hi hvactechfw,
If the unit hums, doesn't that mean it's receiving power?
Hi clocert,
The unit fan, outside, is the one that doesn't work. It turns by hand, but not when I turn the air on. I can hear the furnace fan, it turns on. I'm not sure where the hum is coming from. I'll have another look. Is the compessor working? I don't know. How would I determine that?
Thanks,
...... john

you would know if the compressor was on by the sound it makes. it could be the compressor that is humming. but anyway, if you can start your fan with a stick than your capacitor is bad

the hum may be coming from the contactor. Check what I told you to because they are easy, simple checks and then we will go from there.

Hi,
Turns out that I had missed it. I thought that a hum coming from the unit meant that I had power..... not so, as I'm sure you know. I checked my breaker box, and discovered that the contractor who finished our basement had tripped the air conditioner breaker. When I reset that, all worked fine.
Sorry about putting you guys to all this work.
Thanks again,
.... john
