The Goodman B1370145 Flame Rollout Limit Switch is a genuine OEM 300°F manual-reset safety control for the AMH80703AXAA gas furnace. Mounted on the burner box, this switch senses flame rollout — a dangerous condition where flames escape the heat exchanger — and immediately shuts off the gas valve to prevent overheating, fire, and heat-exchanger damage. It is a critical safety device that must be replaced with the correct temperature rating.

OEM vs. Generic

The genuine Goodman rollout switch is calibrated to trip at exactly 300°F and uses the factory bracket and terminal layout for a plug-and-play fit. Because this is a life-safety component, an incorrectly rated generic switch could trip too late — or fail to trip at all. OEM is strongly recommended, and a repeatedly tripping rollout switch signals an underlying problem (blocked heat exchanger or venting) that must be investigated.

Installation Difficulty

Easy (2/5). Disconnect furnace power, remove the two wire leads, unscrew the switch from the burner assembly, and install the replacement. Verify the switch is reset and never bypass a rollout switch. If it trips again after replacement, call a qualified technician.
