A faulty limit can cause nuisance trips, but if it is reacting to a real overheating issue, that root cause still has to be corrected before the heater is considered fixed.\u003c\/p\u003e\u003cp\u003eThis 140°F auto-reset high limit switch monitors temperature and opens the control circuit if the heater exceeds the specified threshold. Unlike a manual-reset limit, it closes again automatically after the temperature drops back into range. Replacing it restores an important layer of overheat protection in heaters designed for this switch style.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeater shuts down on temperature safety and later restarts automatically\u003c\/li\u003e\n\u003cli\u003eRepeated high-temperature shutdowns occur during operation\u003c\/li\u003e\n\u003cli\u003eLimit switch has failed or is no longer responding correctly\u003c\/li\u003e\n\u003cli\u003eNeed to fix a Raypak heater with overheat safety control problems\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It interrupts heater operation at the rated temperature threshold and then resets automatically after cooling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Used on select Raypak heaters requiring a 140°F auto-reset high limit.
