This 7-foot cable hi-limit sensor (part #6600-110) is a genuine OEM replacement for Sundance Spas hot tubs. The sensor features a 1/4" temperature bulb connected to a 7-foot cable, designed to monitor water temperature and shut down the heater if unsafe conditions are detected. This critical safety component helps resolve HH (high limit), ICE (freeze protection), and OH (overheat) error codes that can leave your spa unusable.
As an exact OEM part, this hi-limit sensor delivers the precise fit and performance your Sundance spa was engineered for. You'll get our exact fit guarantee, same-day shipping on in-stock orders, and a full 1-year warranty for complete peace of mind. The sensor's 7-foot cable length provides the flexibility needed for proper installation in most Sundance spa configurations. Always verify your current sensor's cable length and bulb size before ordering to ensure proper fitment.
