Amana-Goodman 10250802 Limit Switch

The Amana-Goodman 10250802 Limit Switch is a critical safety component designed for high-performance thermal regulation in Goodman and Amana gas furnaces. This 140-180F Auto Limit Switch monitors internal heat exchanger temperatures, serving as a primary safety circuit to prevent overheating conditions. As an authentic OEM furnace replacement part, this high limit control switch features an automatic reset mechanism calibrated to interrupt the electrical circuit if temperatures exceed the 180°F threshold, only restoring the signal once the system cools to 140°F. Engineered for precise HVAC high limit protection, this component ensures the blower assembly and heat exchanger operate within safe parameters. Its durable construction and factory-tested bimetal disc provide consistent response times and long-term reliability for professional service calls and routine system maintenance.

• Direct OEM Compatibility: Verified fit for designated Goodman and Amana furnace blowers and heat exchangers.
• Precise Thermal Calibration: Fixed 140-180°F temperature range specifically tuned for residential gas heating systems.
• Safety Compliance: Acts as a critical fail-safe to prevent manifold and heat exchanger damage.
• Efficient Installation: Standard mounting footprint and terminal configuration for rapid field replacement.
• High-Quality Contacts: Tested for thousands of cycles to ensure consistent electrical continuity and thermal sensitivity.

Is the 10250802 limit switch a manual or automatic reset?

This is an automatic reset switch, meaning it will restore the electrical signal once the temperature drops below the lower set point without technician intervention.

What causes this limit switch to trip frequently?

Common field issues include restricted airflow from a dirty filter, an undersized duct system, or a failing blower motor, causing the heat exchanger to reach the 180°F limit.

Can I use an aftermarket universal limit switch instead of the 10250802?

Using the specific OEM part ensures the thermal response curve matches the original system engineering, maintaining the safety integrity of the furnace.
