The Goodman 0130F00038 auxiliary limit switch is a genuine OEM thermal safety device for the ACSS960804CNAA furnace and related Goodman/Amana models. Color-coded light blue to indicate its specific trip temperature, this normally-closed switch opens the control circuit if it senses excessive heat — for example from a blocked filter, failed blower, or restricted airflow — shutting down the burners to prevent heat-exchanger damage and a fire hazard. A tripped or failed auxiliary limit is a common reason a furnace stops firing or short-cycles.
The OEM 0130F00038 is calibrated to the exact factory trip and reset temperatures that match this furnace's cabinet and heat-exchanger design. Because limit switches are a safety component, the color-coded OEM part removes any guesswork — generic substitutes with the wrong setpoint can either nuisance-trip or, worse, fail to trip when needed. Always replace a safety limit with the correct OEM rating.
Easy — about 10 minutes. Disconnect power, note wire positions, remove the two mounting screws, transfer the spade connectors to the new switch, and reinstall. Confirm the replacement color/part number matches before installing.
