Fluidra - Motor Run Capacitor 3.5 µF / 440 V for MD5 AG Pump

Fluidra – Motor Run Capacitor 3.5 µF / 440 V for MD5 AG Pump

This is the genuine Fluidra replacement run capacitor for the MD5 AG (aluminium grey) pool pump motor, rated at 3.5 microfarads and 440 volts. The run capacitor stays active in the motor circuit throughout operation, maintaining the correct phase shift in the auxiliary winding to keep the motor running smoothly and efficiently. Replacing a faulty capacitor is one of the most common fixes when a pool pump motor hums but fails to start, or trips its breaker shortly after start-up.

Compatibility

This capacitor is a direct OEM replacement designed specifically for the Fluidra MD5 AG pool pump motor (aluminium grey housing). Always verify the µF and voltage rating on your existing capacitor before ordering, and cross-reference the assembly model to ensure a precise fit. It is not intended for other pump or motor families within the Fluidra range.

Why Genuine Matters

A genuine Fluidra capacitor is matched exactly to the electrical specification of the MD5 AG motor windings. Using an incorrect capacitance or voltage rating can reduce motor efficiency, cause premature winding failure, or create a safety hazard. Genuine parts carry the correct tolerances and are built to Fluidra’s quality standards, giving you confidence in both performance and longevity.

Installation

Always isolate mains power completely before opening the motor’s electrical end cover. Note that capacitors can retain a charge even after power is disconnected — discharge the old capacitor safely before handling. The capacitor connects directly to the motor’s auxiliary winding terminals; ensure the spade connectors seat firmly. Given the electrical nature of this repair, installation by a qualified technician is strongly recommended.
