Zodiac - Compressor Suction Gas Temperature Sensor for Pool Heat Pumps - 75311R0522

Zodiac – Compressor Suction Gas Temperature Sensor for Pool Heat Pumps

This is a genuine Zodiac OEM replacement compressor suction gas temperature sensor (part no. 75311R0522), designed for use in Zodiac pool heat pumps. It monitors the refrigerant gas temperature at the compressor suction point, providing the control board with critical data to regulate the refrigeration cycle safely and efficiently.

A faulty or disconnected suction gas temperature sensor will trigger a fault code on the heat pump display and can prevent the unit from operating correctly. Replacing it with a genuine Zodiac part restores accurate refrigerant circuit monitoring and protects the compressor from running under unsafe conditions.

Compatibility

This sensor is a direct OEM replacement for the following Zodiac/Fluidra heat pump models and assemblies (Fluidra exploded views): 77252, 77254, WH000583, WH000585, WH000593, and WH000595 — covering Zodiac PX25 and Z250iQ series heat pumps among others. Always cross-reference your unit’s exploded view or service manual before ordering to confirm fitment.

Why genuine matters

Using a genuine Zodiac part ensures the sensor meets the original electrical and thermal specification required by the heat pump’s control board. Aftermarket sensors with incorrect resistance curves can cause misreadings, nuisance fault codes, or inadequate compressor protection — risks that a genuine OEM component eliminates.

Installation

Replacement of refrigeration circuit sensors involves working in proximity to the compressor and refrigerant pipework, which can reach high temperatures and pressures. This work should be carried out by a qualified pool heating technician or refrigeration engineer. Ensure the heat pump is fully powered off and allowed to cool before beginning any sensor replacement.
