I have an, I believed 2000, Carrier air condition that just died yesterday night. I believed it still receives power because I can hear a low noise coming from the a/c but the fan on the a/c is not running. Any help?
The model is: 38TR030300
Any help is much appreciated.

oh gosh have you ever come to the right place everyone here is really helpful. First thing before you do anything else with the unit trying to start take a small stick and give the fan blade a push in the direction that it normally runs (note the air comes up so push it in the direction so that the air would be pushed up) report back your results ASAP also while pushing on the blade please note any stiffness or resistance to turning, the blade should move very easily

The low noise may be the contactor. Check your circuit breaker and/or fuses.

Many thanks for all your suggestion. I tried and the fan does turn easily but nothing happened other than the low humming noise. I did try the circuit breaker too..switch on and off again. I at least thought it could be the condenser fan motor so I took it out. It was very hot eventhough it has been died for 2 days now. So that lead me to believed that it could be the fan motor.
At this moment I am looking to replace the fan motor. The Model number is 5KCP39EG, RPM: 1100, Euip. MFRS: HC39GE23RA.
The only useful page I found regarding the model I have is this page (http://americanhvacparts.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=MOT39GE237A&Category_Code=m-230-1phcm). One thing is that the price is quite expensive. So my next question is that, what about the "Replaces Motor Part Numbers" section on that page? Will those part nubmers work for my fan motor?

Just make sure you get the same Hp and RPM and that it turns the same way. Also get a new capacitor with it. Dont know if you can by at them . But try Grainger and Johnstone supply.

Don't mean to start a debate but I would look at amperage rating more than hp. Many manufacturers have their motors built special and if you go by hp alone you may get too weak of a motor.

Again, many thanks for all your suggestion. Is the one listed in my post above works? Will someone show me what a capacitator looks like or where it is located on the A/C?
Is there a way to test if it is if the fan motor has failed or not? I just want to make sure that the fan motor I'm replacing is fact the cause of this problem. I heard that once I purchased the part, I can not return and it cost around $200. I just want to make sure that it is so I don't waste my $200.

definitly buy the capacitor and replace it before spending 200 bones on a fan motor (man that sounds steep to me) a capacitor should be less than 25 bones even if it is dual capacitor. here is a site that explains about how they work i think it has pics also http://www.yorkcapacitor.com/products-motor%20run.html

Thank you so much! I was not only going to buy the fan motor. I almost lost $1,500 for a totally new A/C unit. Luckily there is a guy who offers to come over and help me diagnoze, and guess what? You guys are absolutely right! It was the capacitor. I replaced the capacitor for $22 and it work just fine.
Again, thank you so much!
