High Limit Sensors
High limit sensors are a critical safety feature in every hot tub and spa, designed to shut down the heater if water temperature exceeds a safe threshold. A failed high limit sensor can cause nuisance shutdowns or, conversely, allow dangerous overheating. Replacing a faulty high limit sensor restores proper heater protection and reliable operation. At Spa Guy Parts, we stock high limit sensors for a wide range of spa heater assemblies and control systems. Shop now—free shipping over $75.
