Amana-Goodman 10728312 Limit Switch

The Amana-Goodman 10728312 Limit Switch is a critical OEM furnace safety control designed for precise thermal monitoring within the heat exchanger assembly. Engineered as a fixed temperature limit switch, this component features an automatic reset configuration with a calibrated opening temperature of 160°F and a closing temperature of 120°F. It utilizes a 90-degree strap angle mounting bracket for secure installation in high-vibration environments common in Amana and Goodman gas furnaces. The electrical interface consists of standard 1/4-inch quick-connect terminals, ensuring a compatible fit with existing wiring harnesses. Field-tested for high-limit reliability, this switch prevents overheating by interrupting the 24V circuit to the gas valve when plenum temperatures exceed safety thresholds. For technicians performing HVAC furnace repair, this genuine Goodman replacement part ensures the system maintains its original safety certification and operational specifications.

• Precise Thermal Calibration: De-energizes the system at a 160 degree trip point to prevent heat exchanger damage.
• Automatic Reset Logic: Restores circuit continuity once the temperature drops to 120 degrees Fahrenheit.
• Durable Construction: Features a robust 90-degree strap mounting for stable positioning within the airflow path.
• Standardized Connectivity: Equipped with male spade terminals for seamless integration into OEM HVAC control circuits.
• Verified Compatibility: Specified for use in a wide range of Amana and Goodman residential heating units.

Common Questions

What causes a limit switch like the 10728312 to trip frequently?
Repeated tripping is usually indicative of airflow restrictions, such as a clogged furnace filter, undersized ductwork, or a failing blower motor, rather than a faulty switch.

Is the 10728312 limit switch compatible with other furnace brands?
While functionally similar to other L160-40 switches, this specific part is optimized with a 90-degree strap angle for Goodman and Amana equipment; verify the mounting orientation before attempting cross-brand installation.

Can I bypass this switch for testing purposes?
Technicians may momentarily jump the switch during HVAC troubleshooting to confirm a failure, but the unit must never be operated permanently without a functioning 10728312 limit control.
