This normally-closed thermal safety switch mounts on the heat exchanger \/ furnace ceiling and opens the circuit if supply-air temperature climbs too high — protecting the exchanger from cracking and preventing a fire hazard. A tripped or failed limit is a leading cause of a furnace that heats then shuts off, or a blower that runs constantly. If the switch is stuck open, the furnace won't fire at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 1370902S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e High-limit thermal safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Setpoint:\u003c\/strong\u003e 210°F (L210)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e 3-inch insertion depth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e Goodman GSU080-4 gas furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact \u003cstrong\u003e210°F\u003c\/strong\u003e trip point and 3-inch probe length specified for this heat exchanger. Substituting a universal limit with the wrong setpoint or depth risks premature nuisance trips (short cycling) or, worse, failing to trip when the furnace truly overheats. Because this is a safety component, we strongly recommend the OEM part.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Two mounting screws and two spade terminals.
