This normally-closed thermal safety control mounts to the heat exchanger bulkhead and continuously monitors supply-air temperature. If airflow is lost or the furnace overheats, the switch opens at its 200°F trip point to shut down the burners, protecting the heat exchanger and your home from unsafe operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: B1370189\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit \/ temperature safety switch\u003c\/li\u003e\n\u003cli\u003eTrip point: 200°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, auto-reset\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4 in. male quick-connect spades\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana ADV80905CXA and related 80% AFUE furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory-original Goodman part calibrated to the exact 200°F set point specified for the ADV80905CXA. Generic universal limit switches often carry a different trip temperature or mounting footprint, which can cause nuisance lockouts or, worse, allow overheating. For a safety control, the OEM match is the reliable choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eReplacement is a two-screw job for most homeowners: shut off power and gas, remove the burner-compartment door, disconnect the two spade terminals, unthread the two mounting screws, and swap in the new switch. Reconnect and restore power. Typical time is 15–20 minutes. When in doubt, have a licensed HVAC technician confirm the fault before replacing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057511514483,"sku":"GOODMAN-3440","price":9.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-200f-primary-limit-switch-for-adv80905cxa-furnace-b1370189","provider":"National HVAC Parts","version":"1.0","type":"link"}
