This flame rollout switch mounts on the burner assembly and interrupts the gas valve circuit if it detects a dangerous 300°F flame-rollout condition, shutting the furnace down before heat can escape the combustion chamber. A failed or nuisance-tripping rollout switch is one of the most common reasons a furnace locks out on a call for heat.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 300°F (open-on-rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual-reset flame rollout limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Combustion \/ flame-rollout safety cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS81155CNAA and compatible Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1370145\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003egenuine Goodman OEM switch\u003c\/strong\u003e calibrated to the exact 300°F trip point the furnace was engineered around.
