Amana-Goodman B1370109 Temp Switch

The Amana-Goodman B1370109 is a critical OEM replacement stack overtemp switch designed for specific residential furnace and heating applications. This high-limit safety control is engineered with a factory-set trip point of 150 degrees Fahrenheit, providing essential thermal protection by interrupting the burner circuit if flue or cabinet temperatures exceed safe operating parameters. As a genuine HVAC replacement part, it ensures exact fitment and calibration, maintaining the safety integrity of the original equipment without the calibration drift often seen in universal aftermarket alternatives.

Field technicians frequently specify the B1370109 temperature switch for troubleshooting "open limit" fault codes or persistent furnace short cycling. This 150-degree limit switch is built for durability in high-cycle environments, featuring a robust housing and precise bimetal disc for reliable sensing. When diagnosing Goodman furnace safety switches, verify that airflow obstructions or blower failures aren't the root cause before replacing the sensor to ensure long-term system reliability.

• Genuine OEM Component: Ensures 100% compatibility with Amana and Goodman HVAC systems including GUN series models.
• Precise 150°F Calibration: Specifically rated for stack over-temperature protection to prevent heat exchanger damage.
• Snap-Action Reliability: Quick-response bimetal design provides a clean break in the electrical circuit during overtemp events.
• Standard Terminal Connections: Designed for rapid field installation with existing wiring harnesses.

• What causes this switch to trip? Typically, a 150F trip is triggered by restricted airflow, a failing inducer motor, or a blocked flue vent.
• Can this be used as a universal rollout switch? No, this in an OEM-specific stack over-temperature switch; always match the temperature rating and part number exactly to the manufacturer's data plate.
• How do I test the B1370109? Perform a continuity test using a multimeter; the circuit should be closed under normal room temperature conditions and open when it reaches the 150°F threshold.
