PSH - Motor Run Capacitor 20 µF – Pack of 4 (Mini, ND.1, ND.2) - 4550310R

PSH – Motor Run Capacitor 20 µF – Pack of 4 (Mini, ND.1, ND.2)

This is the genuine PSH replacement run capacitor rated at 20 microfarads (µF/MF) for the PSH Mini, ND.1, and ND.2 single-phase pool pump motors. The run capacitor maintains the correct electrical output to the motor windings during operation, keeping the pump running smoothly and efficiently. Sold in a convenient pack of 4, it is the OEM part referenced as position 18 on the PSH exploded-view diagram.

Why the capacitor matters

The run capacitor remains in the motor circuit for the entire duration of pump operation, helping to sustain motor winding performance at speed. A failing capacitor can cause erratic shutdowns, tripped circuit breakers, or motor overheating. Replacing it promptly with a correctly rated genuine part protects the motor from further electrical damage and avoids the far greater cost of a full motor replacement.

Compatibility

This capacitor is designed and specified by PSH for use in their Mini, ND.1, and ND.2 pool pump models. Always match the exact microfarad (µF) rating of the original capacitor — substituting a different value can lead to poor motor performance or damage. If you are unsure which capacitor your pump requires, cross-reference the exploded-view diagram at position 18 or contact a qualified technician.

Installation

Always isolate the power supply at the circuit breaker before beginning work, and discharge any residual charge from the old capacitor before handling it. The capacitor is typically located under a cover on the motor housing, secured by screws. Reconnect terminals carefully and restore the cover before returning the pump to service. Professional installation is recommended if you are not familiar with pool pump motor electrics.
