Mounted on the heat exchanger bulkhead, it monitors supply-air temperature and shuts off the burners if the plenum overheats — typically from a dirty filter, closed registers, a failing blower, or restricted return air. Restoring the correct-rated limit prevents heat-exchanger damage and stops the furnace from short-cycling on over-temperature.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Auto-reset primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e Goodman GMV80905CXA (verify against your rating plate)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e OEM factory limit control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1370198 uses Goodman's exact 150°F set point, mounting flange, and terminal spacing, so it drops in without adapting the wiring. Generic limits with a different trip temperature can nuisance-trip or allow the exchanger to overheat. On a safety high-limit, match the factory part exactly.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e Cut power at the breaker, disconnect the two terminals, remove the mounting screws, and swap in the new switch.
