Generic or universal limits often carry a different set point or mounting footprint, which can cause nuisance lockouts or, worse, fail to trip at the correct temperature. For a safety-critical part like a limit switch, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate.\u003c\/strong\u003e Replacement requires shutting off gas and power, removing the burner-compartment panel, transferring the wiring connectors, and remounting the limit on the heat exchanger or blower deck.
