Zodiac – Low Pressure Switch for Heat Pump PX50 (WH000430)

This is the genuine Zodiac replacement low pressure switch for the PX50 pool heat pump (model WH000430). The low pressure switch is a critical refrigerant-circuit safety component that monitors the suction-side pressure of the compressor and triggers a protective shutdown if pressure falls below a safe threshold, preventing compressor damage and costly failures.

So funktioniert es

In a pool heat pump’s refrigeration cycle, the low pressure switch sits on the low-pressure (suction) side of the compressor. If refrigerant pressure drops abnormally — due to a refrigerant leak, a blocked evaporator, or restricted airflow — the switch opens the safety circuit and stops the unit before internal damage can occur. Replacing a faulty switch restores this essential layer of protection and gets your heat pump running reliably again.

Kompatibilität

This part is designed and approved exclusively for the Zodiac PX50 heat pump, parent model reference WH000430. It corresponds to position 49 in the official Fluidra exploded-view diagram. Always verify your full model reference before ordering to ensure a correct fit.

Warum Echtheit zählt

As an official Fluidra/Zodiac spare part, this switch is manufactured to the exact pressure ratings and electrical specifications required by the PX50. Using a non-genuine substitute risks incorrect cut-out thresholds, voided warranties, and potential compressor failure — making like-for-like replacement with a genuine part the only advisable option.
