Zodiac – Fan Motor Control Board for PX50 Heat Pump (WH000437)

This is the genuine Zodiac replacement fan motor control board (PC board) for the Zodiac PX50 Full Inverter pool heat pump, model reference WH000437. It is the dedicated electronic board that drives and regulates the variable-speed DC fan motor, enabling the PX50’s intelligent speed control across its full 10-speed range. Sourced directly from Fluidra and listed as position 61 in the official exploded-view diagram.

Kompatibilität

This board is designed exclusively for the Zodiac PX50 heat pump, model WH000437. The PX50 range supports pools from 35 m³ to 150 m³ with heating outputs between 6.3 kW and 24 kW. Always cross-reference your heat pump’s model label and the Fluidra exploded-view diagram (position 61) before ordering to ensure an exact match.

Warum Echtheit wichtig ist

The Zodiac PX50 relies on Full Inverter technology, where the fan motor board continuously modulates fan speed across Boost, Smart, and Ecosilence operating modes to balance performance, energy use, and noise. A genuine Zodiac board is engineered to communicate correctly with the main control unit and inverter compressor, maintaining precise speed regulation. An aftermarket substitute risks disrupting this calibration, potentially triggering fault codes or reducing efficiency.

Installation

Replacement of the fan motor control board involves working inside the heat pump’s electrical enclosure and handling inverter-rated components. This work should be carried out by a qualified HVAC/R or pool heating technician familiar with Zodiac PX50 service procedures. Disconnect and isolate all power supplies before starting, and refer to the official Fluidra service documentation for the WH000437.
