Zodiac R0457400 High Limit Wire Harness Switch Assembly Replacement for Select Zodiac Jandy Legacy and LXi Pool and Spa Heaters

Confirm it is a harness assembly

This listing identifies the item as a high-limit wire harness switch assembly replacement for select Zodiac Jandy Legacy and LXi pool and spa heaters. The important distinction is that this is an assembly with wiring, not just a standalone limit switch.

• Look at the failed component: if it includes a harness, connector, or mounting bracket, compare those details before ordering.
• Match the old part number R0457400; other high-limit switches may look similar but not have the same harness termination.
• If your heater uses only a limit switch without a matching harness, this assembly may not be the right replacement.
• Do not splice a replacement harness unless the connector, wire length, and mounting all match.
• A wrong harness can leave poor contacts or unsafe operation.
• Electrical diagnosis and installation should be done by a qualified technician.
