when I came home tonight after being on vacation the outside compressor for my air conditoner was buzzing the fan was not running and the house was around 90 degrees inside I turned of the air conditoner but it is going to be hot tomorrow. any thoughts. 

[looking for an answer]

I checked the unit today the model# is 38ck04835 and the serial# is 4894E09359 I moved the fan blade by hand and it turned very easily could the fan motor be burnt out.

It could be a bad:

CAP CAPACITOR (DUAL RUN) 

80 MFD + 5 MFD at 370 volts

HC93CA081

If you have a single CAP at either rating, you could try it in the repespective circuit.

Sorry but I have no caps of that type. However I have not attempted repair of my A/C unit ever where is this cap located is it in the outside compressor or is it in the inside unit?  How would I be able to check the cap with an voltmeter/ohmmeter.

[looking for an answer]

bad news sports fans the capictor is good the fan is burt out and the compressor is on its last legs. The technican I had check it suggested I replace the system.  does anyone have a suggestion, and why do the A/C companys keep the price of their systems a secret?

 

[RegUS_PatOff]

I'd still try a Cap if you can find someone that has one .....

OR try taking the CAP to another HVAC store for testing ..

I bought a new capictor and replaced it, The unit still did not work.

If anyone is keeping prices to himself, find another technician.

How did this technician decide the unit is on it's last legs.

Did he "Meg-Ohm" the compressor ? Use any type of test equipment ?

Too many "Salesmechanics" lately. JMHO

It was not the tech keeping the prices to himself.  He used a tester to check  the unit and he used an ohm meter with an amp clamp on it to check the fan. Check out any AC replacement site they do not list the prices of their systems they only list how much you can save and how much rebates are. The tech was quoting me 3k to 4k depending on the system, I like to comparsion shop.

I replaced the compressor fan AC is working fine.

I think my Bryant (Carrier) A/C has been reading these messages ...

Today, I noticed the Condenser Fan not working.

Capacitor tested OK, but recommends replacement when replacing Motor.

Motor doesn't turn easily

Looks like a FASCO D917 may work for you also.

Check this one out: http://www.famousparts.com/dfatoencofan.html

I've used FamousParts and have had good service from them.

Attached is the Fasco Motor catalog page that has D917 specs.

I carry two low cost "universal" condenser fan motors on my truck . They are called RESCUE by Emerson. Wholesale supply house cost is about $65 .

http://www.johnstonesupply.com/corp/OnlineCatalog/ProductDetails/tabid/1780/Default.aspx?Product_Code=S81-133

The rescue motors are good for any HP between 1/3 hp and 1/6 hp. One motor is 825 RPM(part #5464) and the other is 1075 RPM(part#5462)

These motors are great because they can be used for most condensers. They have all the mounting holes and studs and you ever will need. They work with RHeem/rhudd side tap mount , Trane and carrier stud bottom mount, top stud mount, belly band mount , and probably a few other mounting

possiblities I havent found yet.

The downfall is they are a standard 48y frame, so if your OEM motor is shorter than a standard 48y frame , It may not fit in the space available.

original GE Condenser Fan Motor

How long do A/C systems last ? (Wisconsin weather)

19 yr old Bryant 10.0 EER Copeland Scroll Compressor

Condenser has some rust

Evaporator Coils have rust

[ACtechGUY]

COOL!!! Like your fan.

Now, how long do a/c's last????????? Anywhere from 10 years to 40 years. How is that for not answering the question?

Really, If you have a (WOW!!) First generation scroll compressor that is still running, you are doing very well.

You are really on borrowed time at this point. The compressor could fail at any time , or it may last another 15 years. You never know when a compressor will go. Most of the time there is no indication of a problem until the compressor dies.

Don't worry about the rust in the evaporator until a refrigerant leak develops. And it will leak someday. Carrier(and many others) has a real problem with leaks where the rusted steel comes in contact with the copper u-bends.

OK, thanks, I'll do the new Condenser Fan and have whatever (each) part replaced when it dies ...
