Description
The Jandy High Limit Switch Harness R0457400 is an authentic OEM wiring assembly designed for Jandy LXi and LRZE pool and spa heaters. This harness forms the electrical bridge between the high limit switches and the main control board, carrying the critical safety signals that trigger an automatic shutdown when water temperature exceeds safe operating limits. Without a functioning harness, the heater’s overheat protection cannot communicate properly, putting expensive components at risk. Built to Jandy’s factory-grade quality standards, this harness delivers long-lasting signal integrity and installs quickly as a direct replacement in all supported models.
