When the temperature reaches the \u003cstrong\u003eopening threshold of 110°F\u003c\/strong\u003e, the switch opens to interrupt the circuit and protect the system. Once temperatures drop back down to \u003cstrong\u003e95°F\u003c\/strong\u003e, the switch automatically resets and closes the circuit, restoring normal operation without manual intervention.\u003c\/p\u003e\n\n\u003ch3\u003eAuto-Reset Functionality\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eauto-reset feature\u003c\/strong\u003e eliminates the need for manual resetting after the switch has been triggered. Once system temperatures return to the safe closing threshold of \u003cstrong\u003e95°F\u003c\/strong\u003e, the limit switch automatically restores circuit continuity, ensuring minimal downtime and consistent system performance.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eThis is a \u003cstrong\u003egenuine Rheem OEM replacement part\u003c\/strong\u003e, engineered to meet the exact specifications required for compatible Rheem heating equipment.
