Hayward Temperature Sensor

This sensor is designed as a genuine replacement part for specific Hayward models. Please verify your salt system's model number against the HPX2000-3242 specification to ensure compatibility before purchasing.

Salt chlorination systems rely on accurate water temperature readings to determine when to generate chlorine. If the sensor fails or provides incorrect data, the system may stop producing chlorine or operate inefficiently, potentially leading to water quality issues.

Common signs of a failing sensor include erratic temperature readings on your control panel, error codes related to the salt cell, or the system failing to generate chlorine despite the water being at the correct temperature. If your system displays a temperature that is clearly inaccurate, the sensor is likely the culprit.

Yes, this is generally considered a straightforward replacement for those comfortable with basic pool equipment maintenance. You will need to turn off power to the pool equipment and ensure the plumbing is isolated before installation to prevent water loss.

Typically, this sensor is plug-and-play and does not require manual calibration. Once installed and connected to your Hayward control board, the system should automatically recognize the new sensor and begin displaying accurate temperature readings.
