Aftermarket switches with a mismatched temperature rating will nuisance-trip on normal heating cycles or, worse, fail to open when they should. Because this is a life-safety control, OEM calibration matters.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5)\u003c\/strong\u003e — Cut power, unplug the two spade terminals, remove the mounting screws, and swap in the new switch.
