Mounted on the heat exchanger\/burner assembly, it monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing a fire hazard when airflow is restricted (dirty filter, blocked ducts, or blower failure). A furnace that lights then shuts down on the limit, or won't fire at all, often has a failed or tripped primary limit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Primary High-Limit Temperature Control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Auto-reset overheat safety shutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman GCH950703BXAB and cross-compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Direct-fit OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162904 is calibrated to the exact trip temperature specified for this furnace and uses the correct mounting bracket and terminal layout. Generic limit switches frequently differ in trip point or footprint — a mismatch on a safety control is not worth the risk. The OEM part is strongly recommended for this application.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — remove two mounting screws and disconnect the wire leads, then reverse.
