pool pump start and run capacitor

I have a waterway HI-FLO 48 Frame Pump. Part # PH2200-6RP. Model SD-20-2N11CD

The motor has 2 speed (low & high). It works fine at low position but it just hums at high position.

Does this sound like a capacitor issue?

If it is, does anyone know the correct start & run capacitor that this motor has and the cost?

I want to order the part first before i open up the motor. At least it is running on low position setting.

If it help, here is the motor info:

Type F/C = Century, Mexico

Motor Mod: C48AA70A79R, SER: 31913J2       HP 2.0 - .25 SPL

Volt: 115,  Amps: 13.5/4.7

PH = 1,  Code = E

RPM = 3450/1725,   FR = 48Y,  HZ = 60

AMB = 40 celcius,   Time rating = CONT

thanks in advance

Thank you for contacting Inyo. It does sound like one of the capacitors has gone bad. The run capacitor is part number 5270-08 and the start capacitor is part number 5270-10.
