OEM Jandy High Limit Switch Set R0457200 includes two precision-engineered switches that safeguard Jandy LXi pool and spa heaters from overheating. These temperature-sensitive switches shut down the heater when water temps rise beyond acceptable limits, preventing internal damage and maintaining user safety. Designed for direct compatibility with LXi models, this set provides added reliability with dual-switch redundancy. Ideal for proactive maintenance or replacing failed components, it restores the heater’s thermal protection system to OEM factory performance.
