I have a RUUD UAKA-048JAS and the fan has stopped turning. I can get it started by turning it but it eventually stops. Originally, I thought that the fan motor needs to be replaced, but after reading other posts, I realize it could be the capacitor.
It looks like the model number on the fan motor is 51-21853-03. I'm not sure about the capacitor. My plan is to replace both the fan and the capacitor ...
