A bad switch can cause nuisance shutdowns or leave the heater without the temperature protection it was built to have.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrequent high limit shutdowns during heating\u003c\/li\u003e\n\u003cli\u003eHeater stops on temperature safety for no clear reason\u003c\/li\u003e\n\u003cli\u003eFaulty switch causes nuisance trips or inconsistent operation\u003c\/li\u003e\n\u003cli\u003eNeed to fix a Raypak heater with temperature safety control problems\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It shuts the heater down at the rated temperature threshold to help prevent overheating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Used on select Raypak pool heaters.
