The Goodman B1370145 flame rollout limit switch is a genuine OEM 300°F manual-reset safety control for the AMS80453AXA gas furnace and compatible Goodman/Amana models. Mounted on the burner box, it detects abnormal flame rollout caused by a blocked heat exchanger or venting problem and shuts off the gas valve to protect your home. A tripped or failed rollout switch is a common cause of no-heat lockouts.

Specifications

Type: Flame rollout limit switch (manual reset)
Trip temperature: 300°F open
OEM part number: B1370145
Reset: Manual push-button
Terminals: 1/4 inch quick-connect
Fits: Goodman/Amana AMS80453AXA and select 80% AFUE furnaces

OEM vs. Generic

The OEM Goodman B1370145 is calibrated to trip at the exact 300°F design set point, so it protects without nuisance shutdowns. Generic switches may use looser tolerances that trip early or, worse, too late. Because this is a life-safety component, we strongly recommend the OEM part.

Installation Difficulty: Easy

Remove two mounting screws, transfer the two spade wires, and secure the new switch. A safe swap for handy homeowners with power and gas off. IMPORTANT: If the switch was tripped, diagnose the root cause (blocked flue, cracked heat exchanger, dirty burners) before returning the furnace to service.

Genuine Goodman OEM safety switch — do not substitute with unrated parts.
