Description
The Swimables Hi Limit Switch SW-41-063 is a vital safety device that monitors water temperature and automatically shuts down the heat exchanger the moment readings climb above the safe threshold of 135°F. A failed high limit switch typically triggers an HLS error code on your heater’s display, signaling that immediate replacement is needed. Because this switch is a one-time-use safety component, it cannot be reset and must be swapped out with a new unit. The SW-41-063 is engineered for broad compatibility across most Pentair MasterTemp and Sta-Rite Max-E-Therm Natural Gas swimming pool heaters.
