The 12' Cable J-400 Sensor 6600-181 is a genuine Jacuzzi temperature sensor designed for J-400 series spas manufactured from 2010 to present. This OEM replacement part features a 12-foot cable length, providing the reach needed for proper installation in your spa's control system. Temperature sensors are critical components that monitor water temperature and communicate with your spa's control board to maintain optimal heating performance.
When your J-400 spa displays error codes like HH, ICE, or OH, a faulty temperature sensor is often the culprit. At Bubbles Supply, we guarantee this sensor will fit your J-400 series spa exactly as intended, backed by our 1-year warranty and same-day shipping on in-stock items. Proper sensor placement and secure cable connections are essential during installation—ensure the sensor tip is positioned correctly in the heater assembly for accurate temperature readings.
