Mounted on the burner assembly, this safety control opens the ignition circuit if flames roll out of the combustion chamber — a critical protection against overheating, blocked venting, or a cracked heat exchanger. When your furnace ignites and quickly shuts down, a tripped rollout switch is a common cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 300°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset type:\u003c\/strong\u003e Manual reset button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Flame rollout \/ high-limit safety cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bracket-mount, ¼\" spade terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman DHS80453AXA and select Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur OEM B1370145 is calibrated to Goodman's exact 300°F trip point and terminal spacing for a true drop-in fit.
