During standard operation, the circuit remains closed allowing normal system function. When the temperature reaches \u003cstrong\u003e140°F\u003c\/strong\u003e, the switch opens, interrupting the circuit to protect the system from overheating. Once the temperature drops back down to \u003cstrong\u003e100°F\u003c\/strong\u003e, the switch \u003cstrong\u003eautomatically resets\u003c\/strong\u003e and closes the circuit, restoring normal operation without requiring manual intervention.\u003c\/p\u003e\n\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cp\u003eThis OEM Rheem limit switch is a \u003cstrong\u003edirect replacement part\u003c\/strong\u003e designed for use in \u003cstrong\u003eRheem heating equipment\u003c\/strong\u003e.
