Engineered to meet strict factory specifications, it preserves the sequence of operation and furnace efficiency. This genuine Amana B1370155 furnace limit arrives in original factory packaging, guaranteeing the reliability required for high-cycle HVAC applications and technical code compliance.

Key Benefits of the B1370155 Limit Switch

• Precise Thermal Protection: Specifically calibrated for 90-120F to prevent overheating within the blower compartment or heat exchanger.
• Automatic Reset Functionality: Restores the circuit automatically once the system cools to safe operating temperatures, reducing unnecessary manual intervention.
• Broad Compatibility: Functions as a high-compatibility L120-30 limit switch for various Goodman, Amana, and Janitrol models.
• OEM Standards: Ensures correct current draw and mounting alignment compared to generic, non-indexed alternatives.
• Direct Replacement: Simplifies repairs by serving as the exact substitute for the legacy 626535R part number.

Common Questions

Is the B1370155 a manual or automatic reset switch?
This is an automatic reset limit switch. It will automatically re-close the electrical circuit once the temperature drops below the 90°F threshold.

What causes this limit switch to trip frequently?
Common field issues include restricted airflow from dirty filters, a failing blower motor, or blocked return air ducts, causing the temperature to exceed the 120F limit.

Can I use an aftermarket L120 switch instead of the B1370155?
While universal switches exist, using this genuine OEM B1370155 ensures the differential and thermal response timing match the original unit’s safety engineering.
