Because this is a safety limit, an incorrect temperature rating or probe length can either nuisance-trip in normal operation or fail to protect the heat exchanger. We strongly recommend OEM for any safety control.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — about 15 minutes. Shut off gas and power, remove the two mounting screws, transfer the wires, and install the new switch at the same depth. Confirm the underlying airflow problem is resolved first.
