Know before you buy
This sensor is designed as a direct replacement for standard Balboa systems using a 2-pin connector. We recommend checking your current sensor's connector type and bulb diameter to ensure it matches the 3/8-inch specification before purchasing.
This component serves a dual purpose: it monitors water temperature for regulation and acts as a high-limit safety switch. It is essential for preventing the heater from overheating the water, which protects both your equipment and the spa shell.
Yes, the 96-inch cable is standard for most residential spa configurations, allowing for routing from the control box to the heater manifold. If your current sensor cable is significantly shorter, this length will provide ample room for a clean, non-kinked installation.
Common signs of a failing sensor include erratic temperature readings on your topside display, the system failing to heat, or persistent 'OH' (Overheat) error codes. If your system is displaying these errors despite the water being at a normal temperature, the sensor is likely faulty.
Installation is straightforward and typically requires only basic hand tools to access the control box. Since it uses a standard 2-pin connector, it is a plug-and-play replacement that does not require specialized electrical training.
