Description
The Jandy Exhaust Temperature Limit Switch R0329400 is a factory-original safety device engineered to track exhaust heat levels in Jandy LX and LT pool and spa heaters. When exhaust temperatures climb beyond safe operating thresholds, this switch triggers an automatic shutdown to protect the heater from thermal damage and potential component failure. Fitting models including the LX250, LX400, LT250, and LT400, it is constructed for lasting performance and precise OEM integration. Adding this part as part of your regular maintenance routine helps preserve equipment integrity and ensures your heater operates safely and reliably throughout every heating season.
