Hi-limit sensors are safety components that help protect heaters and spa systems from unsafe temperature conditions.

The Hydro-Quip Gecko Y Series Hi Limit Sensor (34-0203Y-36-K) is a replacement sensor for compatible Gecko Y Series equipment used in Hydro-Quip spa control and heater applications.

This sensor may be needed when a spa shows high-limit errors, heating interruptions, sensor faults, or inconsistent temperature safety readings after other causes have been checked.

Replacing a faulty hi-limit sensor helps restore safe heating logic and allows the control system to monitor temperature conditions more reliably.
