Condensor fan motor runs slow on RUUD


Its a 5kcp39fgn223as G.E. brand in a RUUD unit.
If it runs slow is the start capacitor stiil good and there is another large
cap too connected to it. If its running slow do you think the motor is just
gone. Its around 20 years old.

Do people ever rebuild these, wonder about that.

The startup that has been replaced some years back.
Its a long round one. The other large one never seems to give
trouble.
I will have to look for one on the net, will check the value of it.
No play in bearing.
Turns real smooth with no play.
Maybe replace the startuo with a
Supco hard start capacitor SPP6 SPP-6 I think that is what was put in it can't read writing on it.
The Run capacitor I don't think has ever been replaced but it looks ok and not swelled up etc.

So you think the old motor is on its last leg. Can these be rebuilt?
Brushes cleaned up etc. People must have done that in the past
before people replaced them.

Will have to get my meter out and see if I have voltage at the run cap
and at the hard start cap. I have replaced the hardstart, they seem to go. The other large cap I have never rplaced and it has never blown or
bulged up, looks real clean.
The old motor might have given up but no smell of burning etc from it.
The old ones I bet are built better then the new ones from CHINA.
