The genuine Goodman switch is calibrated to trip at the exact 150°F rating and mounts with the correct flange and probe depth. Generic switches with different trip points or mounting can cause nuisance shutdowns or, worse, fail to protect the heat exchanger. Always use the OEM-specified rating.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy–Moderate (2\/5)\u003c\/strong\u003e — Remove two mounting screws, transfer the wire terminals, and reinstall on the correct panel.
