Raypak 600890B High Limit Switch 140°F for Pool Heaters
If your heater shuts down on temperature safety, resets only after cooling, or trips high limit conditions even though flow seems normal, the high limit switch is one of the first safety parts to inspect. A bad switch can cause nuisance shutdowns or leave the heater without the temperature protection it was built to have.
This 140°F high limit switch monitors water temperature and opens the control circuit when the heater reaches the specified limit. When it fails, the heater may trip too soon, operate inconsistently, or lose a critical layer of overheat protection. Replacing it restores the temperature safety control that helps protect the heater during operation.
