Zodiac - Evaporator Coil Temperature Sensor for Pool Heat Pumps - 75311R0133

Zodiac – Evaporator Coil Temperature Sensor for Pool Heat Pumps

This is a genuine Zodiac OEM evaporator coil temperature sensor, designed to monitor the refrigerant-side coil temperature inside Zodiac pool heat pumps. It feeds real-time temperature data to the heat pump’s control board, enabling accurate regulation of the refrigerant cycle, efficient defrost management, and protection against coil icing or overheating.

Compatibility

This sensor is a direct replacement part for Zodiac pool heat pumps covered by Fluidra exploded views 77251, WH000582, and WH000592 — including models in the Zodiac Z250iQ (PX25) Wi-Fi series. Always cross-reference your unit’s exploded view diagram or serial number before ordering to confirm fitment.

Why genuine matters

As an original Zodiac spare part, this sensor is built to the exact resistance and tolerance specifications required by the heat pump’s control electronics. An incorrect or aftermarket sensor can cause false readings, nuisance faults, or unprotected coil-freeze events — all of which can lead to compressor damage. Using a genuine part ensures the unit continues to operate within its designed parameters.

Installation

Replacement of the evaporator coil temperature sensor involves accessing the internal refrigerant circuit area of the heat pump and disconnecting the wiring harness connector. While the sensor itself does not require refrigerant handling, working safely inside a heat pump cabinet is best left to a qualified pool heating technician or HVAC engineer.
