A generic switch with the wrong trip temperature can nuisance-trip or, worse, fail to protect. A repeatedly tripping rollout switch signals a deeper issue (blocked flue, cracked heat exchanger) that should be inspected.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Cut power, remove the burner panel, unplug the two spade terminals, unscrew the switch, and install the replacement in the same orientation.
