    What This High-Limit Sensor Does

    The high-limit sensor is a critical safety component that protects your spa’s heater from overheating. It monitors the heater temperature and shuts the system down if unsafe temperatures are detected.

    If your spa shows heater error codes or frequent overheating shutdowns, this sensor may need to be inspected or replaced.


    Troubleshooting Tip Before Replacing

    Before installing a new sensor, check the existing sensor and surrounding heater well for:

    • Calcium buildup
    • Debris
    • Scale or mineral deposits

    These issues can cause false temperature readings, and in many cases a simple cleaning can restore proper operation.
