This normally-closed thermal switch opens at approximately \u003cstrong\u003e120°F\u003c\/strong\u003e to shut down the burner or blower circuit if it detects abnormal heat, protecting the heat exchanger and surrounding cabinet from overheating. A failed or nuisance-tripping auxiliary limit is one of the most common causes of a furnace that starts, then shuts off on a safety lockout.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370155 (OEM Goodman)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Auxiliary high-limit \/ thermal cutoff switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature:\u003c\/strong\u003e 120°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally closed (SPST)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e Goodman DHS80905CXA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine OEM Goodman\u003c\/strong\u003e switch calibrated to the exact factory trip point and mounting footprint, so it drops in without wiring adapters or bracket modification. Universal aftermarket limit switches may carry a different trip temperature or terminal orientation, which can cause premature lockouts or fitment issues. For a safety-critical component, matching the OEM spec is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy (1 of 3)\u003c\/strong\u003e. Replacement typically takes 10–15 minutes: disconnect power, note the two spade terminals, unscrew the switch from the burner box or blower deck, and swap in the new unit. Basic hand tools only.
