Mounted on the heat exchanger or blower shelf, the primary limit monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing hazardous operation. A failed or nuisance-tripping limit is a common cause of no-heat calls and short cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003ePart type: Primary high-limit \/ temperature safety switch\u003c\/li\u003e\n\u003cli\u003eFits: Amana AMVC80603BNCA and cross-compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eFunction: Interrupts gas valve on over-temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAftermarket limits often ship with a generic trip point or mounting bracket that doesn't match Goodman's airflow design, leading to premature nuisance trips.
