The Amana-Goodman 10250804 Limit Switch is a critical OEM furnace replacement part designed for precision thermal monitoring in residential HVAC systems. Engineered as an L150-40F limit control, this component features a fixed 150-degree Fahrenheit opening point and a 40-degree differential, ensuring the heat exchanger operates within safe parameters. It functions as a primary safety device, breaking the electrical circuit to the gas valve if internal plenum temperatures exceed the factory-set limit, thereby preventing equipment damage and hazardous conditions. This Goodman furnace limit switch is a direct replacement for various Amana and Goodman gas furnaces, offering seamless mechanical integration and electrical compatibility through standard spade terminals. For technicians performing diagnostics on furnace high limit trips, utilizing this genuine HVAC limit switch ensures the equipment maintains its original safety listings and thermal response profiles. Installation provides reliable cycling and helps resolve common ignition sequence interruptions caused by faulty or drifting thermal sensors. OEM Precision: Genuine Amana-Goodman replacement part ensures exact calibration to factory specifications for equipment safety. High Thermal Sensitivity: The L150-40F thermal switch provides accurate temperature sensing to protect the heat exchanger from overheating. Wide Compatibility: Designed specifically for use in a broad range of Amana and Goodman furnace models. Durable Construction: Built to withstand the high-temperature environment of a furnace plenum for long-term reliability. Common Questions What are the temperature specs for the 10250804 limit switch? This is an L150-40F limit switch, meaning it is designed to open (break the circuit) at 150°F and close (reset) once the temperature drops by 40°F. Is the 10250804 switch a manual or automatic reset? The 10250804 is an automatic reset limit switch, designed to restore the circuit once the plenum temperature returns to a safe operating range. Can I use a universal limit switch instead of this OEM part? To maintain the safety integrity and specific airflow requirements of Amana and Goodman units, technicians recommend using the genuine OEM 10250804 to ensure the trip points match the original design.
