Jacuzzi & Sundance Spas

Jacuzzi and Sundance temperature sensors are used in Jacuzzi and Sundance spa
control systems to measure water temperature and regulate normal heating
operation. These sensors provide real-time temperature feedback to the control
board so the heater can cycle on and off to maintain the selected water
temperature.

Temperature sensors do not generate heat and do not cause overheating. Their role
is to accurately report water temperature to the control system. When a
temperature sensor fails it may send incorrect readings or stop communicating
with the control board.

Common symptoms of a faulty Jacuzzi or Sundance temperature sensor include
incorrect water temperature displayed on the topside heater not turning on water
heating too hot or too cold error codes related to temperature sensing or unstable
heating operation. Sensor drift corrosion scale buildup or moisture intrusion can
affect accuracy over time.

Jacuzzi and Sundance temperature sensors vary by resistance value connector type
cable length mounting style and system generation and must be matched correctly
to the exact Jacuzzi or Sundance control system. Sensors that appear similar may
not be interchangeable.

Temperature sensors are often confused with hi-limit sensors. While both monitor
temperature they serve different purposes. Temperature sensors regulate normal
heating operation while hi-limit sensors act as a safety shutoff to stop continued
overheating.

Installing the wrong temperature sensor can result in inaccurate readings heater
problems system errors or improper operation.

Before ordering identify the Jacuzzi or Sundance spa model control system name
and existing temperature sensor part number. Many systems require proprietary
sensors for proper operation.

If you are unsure which Jacuzzi or Sundance temperature sensor is correct for
your spa do not guess. Text clear photos of the existing sensor control box and
wiring connections and we will help confirm the correct replacement before you
order.
