Aftermarket equivalents can carry the wrong trip temperature or a different mounting footprint, which may cause short-cycling or failure to protect the furnace. For safety controls, we recommend sticking with OEM.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1 of 5)\u003c\/strong\u003e — Cut power to the furnace, disconnect the two wire leads, remove the mounting screws, and install the new switch in reverse. If the switch is tripping repeatedly, verify proper venting and airflow before assuming the part is bad.
