Fan motor problem

[Eric Dale]

I am trying to locate a GE motor. I cant find it any where online. Can you please help me find this motor or one that is compatible with this motor.

Details:
GE motor
5kcp39fg p719 s
HP=1/3
V=208-230
A=3.20
RPM=1075
HZ=60
CPN=51-21789-01
CAP=7.50/370

 

[Eric Dale]

Could someone tell me what the P719 S means?

I would guess it could be a a date code. Try this search in your favorite search engine:
skcp39fg ge motor

 

[Eric Dale]

Do i need ALL the HP, V, A, RPM CAP and HZ to be the exact same with this one?

I think this is the replacement part:

Suggest that you take another look at the details of what the OP wanted. The picture of the one you recommended is 1/4 HP vs 1/3 HP on the original. Also, the rotation is opposite the original. The amperage does not match.

To the original poster - You can take your motor to any HVAC supply house and they can match it up for you quite easily. Don't forget to replace the capacitor when you replace the motor.

Charles , you’re right I did not look that close. On another site that Terry does not like mentioned on this web site, it said it was a replacement, so I didn’t look all that close. I did find exact matches on a site that sells used equipment but the links do not work on this site either.
The site I did provide the link for, has a number and he could call them to find out if they have the motor or a motor that will work. Here is their number:

Here are other links. I matched to 51-21789-01 ,another number on the label:

See if any of those links help.

What is wrong with your motor ?

For the price of the motor, You may want to have it rebuilt.

The Bearings are about all that go out.

Is your Run cap good ?

You may be better off, going by the model number for what it came out of.

It looks like them replacement motors come in 3, 4 and 5 speed. How many wires does your motor have ?

Do you have a model number for what it came out of ?


Good Luck.

Well the motor is 19 years old. Is time to get a new one. It won't run, is the problem.
The run capacitor is still good. I checked the voltage to it.
This motor has four wires( brown, orange, black, and yellow)
Does the shaft length(3.5) have be the same? What if I find one that is 6 inches long.

I started looking for 5kcp39fg and couldn't find anything that match. So I started looking up the con (51-21789-01) and finding matches except for shaft length.

What is it out of ? Air Conditioner ?

Hard to see from here.

The shaft Length does mater. Some of the motors are scored shaft, and you cut it off.

It is not what goes into the capacitor, It is the voltage that comes out of it, and the current, that is important.

If the fan spins by hand, the cap is most likely bad. Unless a winding (Not likely) or the safety device is open.


Good Luck.

When my fan was running it wasn't blowing really hard. Then on Tuesday it just stopped working. I was and to soon it by hand though.
The condenser fan came on when i pushed the contactor button in. To check the capacitor I switched the attic fan and codenser fan capacitor and the condenser fan came on fine. So both capacitors work. My attic fan won't run at all though. It's a package unit on my roof.

 

[DonL]

Both caps are the same Value ?

They need to be for that test.

Does the attic fan have a T-stat ?

How about a Model Number, so no guessing is needed ?

That motor you have is single speed, I would not pay $200 for one. CPN=51-21789-01

Good Luck.

 

[Eric Dale]

Yes they are the same

 

[DonL]

Yes they are the same

Did you get the polarity correct ? LOL, Trick Question.

I think we doubled.

I did a edit to add a link in my post.

 

[Eric Dale]

The details of the motor is listed in my first post. The serial number is 5kcp39fg. I have a rheem package unit.

 

[Eric Dale]

The shaft is 3.5 inches

http://keithspecialty.com/k/Rheem-51-23023-31.htmhtm will this one work?

 

[DonL]

will this one work?

It says it will replace 51-21789-01.
