waterway executive 56 pump low speed issues

[wompi2305]

I have a spa builders ap1400 #2 hot tub with a waterway executive 56 side discharge pump that is having problems with the low speed coming on with the circulation timer. The pump works fine if started in high speed and then drop down to low speed but will not start on its own in low speed. I got this spot used so I'm not sure if the capacitor on the motor is correct or if the capacitor is wired wrong with both feet sharing the same run capacitor 55 microfarad. Both high and low speeds are on the same terminal and the common is on the opposite side. I've read some of these forums which state the capacitor is engaged with a centrifugal switch. I am familiar with motors having spent years in the field as a HVAC technician. Do spa pumps have a run capacitor on the side of them or start capacitor? Could I be losing voltage across the timer and that could be causing the problem? Any help could be appreciated

If it will start in high and then run when switched to low it is the start capacitor.

My executive 56 waterway pump has 2 capacitors.  It won't run on low speed ,only runs on high speed. What could be the issue

Bad relay on the board, bad motor. Test voltage to the pump at the high and low connections on the circuit board (so black to white and red to white with pump disconnected) and verify that you have good voltage to the pump. If not, pull the circuit board and check the back for burns. If so, it's in the motor or cord.
