Mounted near the burner assembly, this safety device trips and shuts off the gas valve if flame rolls out of the burner box due to a blocked flue, cracked heat exchanger, or restricted combustion air — protecting your equipment and home from overheating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F\u003c\/li\u003e\n\u003cli\u003eType: manual-reset flame rollout limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: opens gas circuit on flame rollout \/ overheat\u003c\/li\u003e\n\u003cli\u003eFits: Goodman DMS80905CNA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOEM B1370145 is calibrated to the exact 300°F trip point Goodman specifies for this burner design. Generic switches with the wrong setpoint may nuisance-trip or, worse, fail to trip when needed. Because this is a life-safety component, we recommend the genuine OEM part for guaranteed calibration and fit.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — roughly 15–20 minutes. Shut off gas and electrical power, remove the burner cover, disconnect the two spade terminals, unscrew the switch, and install the replacement in the same orientation. A repeatedly tripping rollout switch indicates an underlying problem (flue blockage or cracked heat exchanger) that a licensed HVAC technician should diagnose before returning the furnace to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058048024947,"sku":"GOODMAN-9611","price":16.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-300-f-rollout-limit-switch-for-dms80905cna-b1370145","provider":"National HVAC Parts","version":"1.0","type":"link"}
