Zodiac r0719402 Flue Sensor Kit Thermistor Jxiq Heater

Product Description

The ZODIAC r0719402 is a flue sensor kit and thermistor assembly designed for JXiQ series pool and spa heaters. It monitors exhaust gas temperatures inside the flue path and triggers automatic safety shutdowns when temperatures exceed safe operating limits. This OEM-spec component integrates directly with the JXiQ heater's onboard control board electronics. Licensed pool equipment technicians and HVAC service professionals install this part as a direct factory replacement to restore accurate flue temperature monitoring and protect the heat exchanger and other internal components from thermal overload conditions.

The r0719402 is purpose-built for the Jandy JXiQ series in the 200, 260, and 400 model variants. It is typically installed in residential and light-commercial pool and spa heating systems where the JXiQ heater provides gas-fired heating. A failed or out-of-range flue sensor will commonly cause nuisance lockouts, fault codes, or an inability to maintain a heating cycle. Replacing the sensor with this OEM kit restores normal control board communication and accurate exhaust temperature feedback.

Installation Notes

Installation should be performed by a licensed pool equipment technician or qualified service professional. Before servicing, shut off gas supply and disconnect electrical power to the heater at the circuit breaker. Allow the heater to cool fully before handling any flue or exhaust components. Follow applicable local codes and manufacturer service procedures when reconnecting the sensor to the control board harness.
