Amana-Goodman B1370113 120F Limit Switch

The Amana-Goodman B1370113 is a critical high-limit safety component designed for precise temperature regulation within HVAC systems. This OEM replacement limit switch features an auto-reset function, calibrated to trigger at 120°F (L120-30). Engineered for furnace high limit protection, it prevents heat exchanger damage by breaking the circuit when internal temperatures exceed safety parameters. As a genuine Goodman furnace part, it ensures seamless integration and maintains the UL-certified safety profile of the original equipment. This fixed temperature limit control is built for durability in high-cycle environments, providing technicians with a reliable solution for residential and commercial heating repairs. Its L120-30 rating indicates a 120-degree opening temperature with a 30-degree differential, making it essential for proper airflow and burner management. Utilizing this Goodman B1370113 switch ensures accurate thermal response times, reducing nuisance tripping and protecting the blower motor from overheating during operation.

• OEM Precision: Direct Amana B1370113 replacement ensures exact fitment and terminal alignment for faster installs.
• Automatic Reset: Eliminates manual intervention by restoring the circuit once furnace temperature limits return to safe operating ranges.
• Enhanced Safety: Provides critical thermal overload protection, preventing hazardous conditions during airflow failure.
• Broad Compatibility: Engineered for use across various Amana and Goodman HVAC systems, streamlining service truck inventory.

Is the Goodman B1370113 a manual or auto-reset switch?
This is an auto-reset limit switch, meaning it automatically closes the circuit once the plenum temperature drops below the specified differential.

What causes this limit switch to trip frequently?
Frequent tripping is often indicative of restricted airflow, such as a clogged filter, blocked return, or a failing blower motor, causing the heat exchanger to overheat.

Can I replace a 120F switch with a higher temperature rating?
No, always use the OEM-specified temperature rating to maintain the safety integrity of the furnace and prevent heat exchanger fatigue.
