Amana-Goodman 1370913S Limit Switch

The Amana-Goodman 1370913S Limit Switch is a critical safety component designed for specific air handlers and furnaces within the Goodman, Amana, and Janitrol product lines. This replacement high limit switch features a 170-200F auto-reset configuration, ensuring the system interrupts the burner circuit if internal static pressure or airflow issues cause temperatures to exceed safe operating parameters. Rated for L170-20F, it opens at 170°F and automatically closes once it cools by 20°F, preventing heat exchanger damage and maintaining system integrity. As an OEM HVAC replacement part, it ensures precise calibration and terminal alignment for a direct-fit installation. Field technicians should verify furnace limit switch compatibility by checking the existing part number against the manufacturer’s technical data sheet to ensure the temperature setpoints match the original equipment specifications for the specific induction furnace model being serviced.

• Automatic Reset Functionality: Provides continuous protection by cycling the system and resetting once temperatures return to the 20-degree differential range.
• Precision Thermal Calibration: Engineered for a 170-degree trip point to safeguard against over-temperature conditions in high-efficiency heat exchangers.
• Direct OEM Replacement: Guarantees proper mounting footprints and electrical connections for Goodman and Amana air handlers.
• Durable Construction: Built to withstand high-cycling environments common in residential HVAC heating cycles.

What causes a limit switch like the 1370913S to trip repeatedly?
Repeated tripping usually indicates restricted airflow, often caused by a dirty air filter, blocked return ducts, or a failing blower motor. Always check static pressure when replacing this furnace safety sensor.

Can I substitute this with a switch that has a higher temperature rating?
No. Using a switch with a different thermal cutout rating can lead to equipment damage or safety hazards. Always match the 170-200F specs of the 1370913S for the specific application.

Is this switch compatible with my specific Goodman furnace?
Compatibility is determined by the model and serial number of your unit. This HVAC limit control is widely used in Amana/Goodman electric heat kits and gas furnaces; verify the part number in your technical manual.
