Amana-Goodman B1370198 Limit Switch

The Amana-Goodman B1370198 Limit Switch is a critical safety component designed for high-performance HVAC systems, specifically engineered to monitor and regulate internal plenum temperatures. This 120-150F Auto Limit Switch functions as a normally closed (NC) thermal protection device, ensuring the furnace operates within precise thermodynamic parameters to prevent overheating. Operating on an automatic reset mechanism, this OEM Goodman replacement part initiates a circuit break when the upper temperature threshold of 150°F is reached and restores connectivity once the system cools to 120°F. Built for durability in high-cycle environments, it is compatible with a wide range of Amana and Goodman gas furnaces. Integrating this switch ensures the integrity of the primary heat exchanger and maintains the sequence of operation required for system longevity. For contractors performing scheduled maintenance or emergency furnace limit switch replacement, this genuine component provides the exact electrical specifications and mounting footprint required for field reliability.

• Precision Thermal Sensing: Features a fixed 120-150F temperature range for accurate high-limit protection.
• OEM Compatibility: Exact replacement for Goodman furnace parts, ensuring seamless fitment and electrical continuity.
• Automatic Reset Logic: Eliminates manual intervention by resetting the circuit automatically after thermal stabilization.
• Technical Reliability: Engineered to withstand the thermal stresses of modern high-efficiency HVAC equipment.

Common Questions

Does this switch require manual resetting after a trip?
No, the B1370198 utilizes an automatic reset function that re-engages once the temperature drops below the lower set point.

What causes this limit switch to trip frequently?
Frequent tripping usually indicates restricted airflow, such as a clogged filter, obstructed ductwork, or a failing blower motor.

Can I use a higher temperature limit switch instead?
No, for safety and compliance with HVAC technical specifications, you must always use the temperature rating specified by the manufacturer.
