Hi-Limit Sensors

Hi-limit sensors provide an electronic safety cutoff that shuts down your spa's heater if water temperature approaches dangerous levels. These sensors work in concert with the control pack to protect both the equipment and bathers from overheating hazards. A failed hi-limit sensor often triggers persistent error codes or prevents the spa from heating at all. Spa Guy Parts carries hi-limit sensor replacements for major spa control platforms including Balboa, Gecko, and ACC. Free shipping over $75.
