The Goodman B1370145 is a genuine OEM 300°F flame rollout limit switch for AMS80703AXA 80% AFUE gas furnaces. Mounted on the burner box, this manual-reset safety trips and cuts power to the gas valve if flames roll out of the heat exchanger — a critical protection against a cracked exchanger, blocked flue, or dirty burners. A tripped or failed rollout switch will prevent the furnace from firing until the fault is corrected and the button is reset.

Trip temperature: 300°F (opens on rise)
Reset type: Manual (push-button)
Function: Flame rollout / high-limit safety cutoff
Terminals: Standard 1/4" spade connections
Fits: AMS80703AXA and compatible Goodman/Amana furnaces

OEM vs. Generic: The B1370145 is calibrated to trip at Goodman's exact 300°F setpoint with the correct mounting-bracket footprint. A generic switch with a different trip point or bracket can nuisance-trip or, worse, fail to protect at the intended temperature. For a life-safety component, always use the factory-rated part.

Installation difficulty: Easy. A 10–15 minute swap: shut off gas and power, note the wire positions, unscrew the old switch from the burner box, mount the new one, and reconnect the spade terminals. If the switch had tripped, diagnose and clear the underlying overheating cause before returning the furnace to service.
