Zodiac - Gas Suction Temperature Sensor for Pool Heat Pumps - 75311R0074

Zodiac – Gas Suction Temperature Sensor for Pool Heat Pumps

This is the genuine Zodiac replacement gas suction temperature sensor (part 75311R0074), designed for use in Zodiac pool heat pumps. It monitors the refrigerant temperature on the suction side of the compressor, providing the control board with the data it needs to protect the unit and regulate heating output efficiently.

A faulty or failed suction temperature sensor can cause your heat pump to display error codes, shut down unexpectedly, or run inefficiently — replacing it with the correct OEM part restores accurate readings and reliable operation.

Compatibility

This sensor is a direct replacement part for Zodiac pool heat pumps covered by Fluidra exploded views 77251, 77253, 77255, WH000584 (PX25 TD9), WH000586 (PX25 TD12), WH000594, and WH000596. Always verify your model and exploded view reference before ordering to ensure correct fitment.

Why genuine matters

As an original Zodiac spare part manufactured to factory tolerances, this sensor delivers the precise resistance-to-temperature characteristics that the heat pump’s PCB expects. Aftermarket substitutes may produce inaccurate readings, triggering false fault codes or leaving the compressor unprotected.

Installation

Replacement of the gas suction temperature sensor involves working within the refrigerant circuit enclosure of the heat pump. This work should be carried out by a qualified pool heating technician or F-Gas registered engineer. Ensure the unit is fully powered down and isolated before beginning any service work.
