I have a condenser fan motor that has died on my home air conditioning
system. Does anyone know how I can find what a compatible motor would
be for the one that I'm replacing? Here are the specs:

Emerson Model K55HXPRR-5274
1/4 HP
Pt No. 024-25119-000
Volt 208-230
H2 50/60 AMP 1.6 PH 1
R.P.M. 850
Frame 48Y

And recommendations on where to order such a part would be welcomed!

Thanks!
