Air conditioner condenser fan replacement

Does anyone know off hand what fan motor I need to buy for my old luxair ac unit? Replaced the start cap and it ran for 2 days then off. I checked fan resistance and all leads read open. I have a partial ge number, but the bracket was mounted over the plate and part is missing. Model number is so washed out I can't read it.

Number is 9kc 9gge410s. Looks like 3 wire, 3 1/4 inch long 1/2" shaft.

Thanks!

You will need more information.

Do you have a model number for the condenser?
Does the condenser nomenclature give you any information about the fan motor?
Can you read the horsepower rpm and frame size on the motor?

Unfortunately the tag on the side is unreadable.

The motor is 1/4 hp 208-230v 1.3a

I do have a mfg. # the one I can I can read is 024-19891-0000 but the that is on the motor

How does your motor mount to the unit?

Most just use the 4 bolts sticking out of the end of the motor but some have a welded mounting bracket.

Do you know the RPM.

They usually run around 800 rpm or around 1100rpm.


If you are just using the 4 bolts sticking out of the end of the motor, this motor and a 5 microfarad run cap should work.

4 wire universal motors wire up a little differently.

It's 1075 rpm, it mounts with a clamp arrangement onto a frame. The stud one won't work.

I will have to measure and see if it's the same size frame and maybe I could just use it.

Thanks for the replys!

The motor that I posted will cost a fraction of the OEM motor but it will be longer. The shaft may also need to be cut ( although I haven't had to cut one in years).

A universal motor will have a drain plug. The plug should be in the drain hole that ends up on top of the motor. I have seen homeowners leave the plug on the bottom hole and partially fill the motor with rain water in less than one year. The motors shorted out.




A universal motor will be reversible. The air should discharge out of the top of the condenser.

Thank you very much for the link and the advice! I ordered the motor you recommended and will let you know how it works out!

Thanks for the tip about the drain plug(s) I will remove them if they are in there. Or should I just leave them both in if they are plugged?

My thinking says leave the top one in but remove the bottom one?

As for the drain plugs, you're correct. Leave the top one in and remove the bottom one.
