Amana-Goodman 10728331 Limit Switch

Professionals know that a faulty Amana-Goodman 10728331 Limit Switch is a frequent culprit behind short-cycling and rollout issues in high-efficiency furnaces. This 120-160F Auto Limit Switch is a normally closed safety component designed for precise thermal regulation. Engineered with a 3-inch insertion length, this L160-40F limit switch triggers at 160°F to interrupt the burner circuit, preventing heat exchanger damage and ensuring system integrity. As an OEM furnace replacement part, it provides the exact calibration required for Amana, Goodman, and Janitrol units, featuring an automatic reset limit switch mechanism that closes once temperatures drop to 40°F. When diagnosing a gas furnace high limit switch trip, swapping in this genuine HVAC temperature sensor restores the factory-spec safety sequence. This component is compatible with a wide range of Amana and Goodman models, including the GUID and GUIS series, maintaining the specific airflow-to-heat ratio needed for reliable operation.

• OEM Compatibility: Precision-engineered for Amana, Goodman, and Janitrol gas furnaces.
• Automatic Reset: Self-correcting logic restores the circuit once the plenum cools to 40°F.
• Safety Calibration: 160°F open temperature prevents catastrophic heat exchanger failure.
• Industrial Build: Durable construction designed to withstand thousands of thermal cycles.

What causes a 10728331 limit switch to trip?
Trips are typically caused by restricted airflow, such as a clogged filter, a failing blower motor, or undersized ductwork forcing the heat exchanger past the 160°F threshold.

Is the 10728331 an automatic or manual reset switch?
This is an automatic reset limit switch. It will automatically re-close the circuit once the internal temperature drops sufficiently, though persistent tripping indicates an underlying airflow issue.

Can I use this as a universal replacement?
While it fits many Goodman-manufactured brands, always verify the L160-40F rating and the 3-inch insertion depth against your specific model's wiring diagram.
