Description
This Motor Start Capacitor is designed for use with 115V spa and hot tub pump motors across multiple brands.
Specifications: 161-193 MFD, 115v, dimensions 1-7/16" diameter x 2-3/4" height
Troubleshooting tip: If your pump powers on but only hums without starting, the start capacitor may need replacement. You can test this by manually rotating the rear shaft with a screwdriver or switching to high speed momentarily—if the motor runs afterward on low speed, the capacitor is likely failing.
Important: A failing capacitor is typically a symptom of a larger motor issue rather than the root cause. While replacement may restore operation temporarily (often for days to weeks), the underlying problem may persist and cause repeated failures.
To select the correct replacement, match both the microfarad rating stamped on your existing capacitor and verify the physical dimensions.
