Amana-Goodman 10123535 Limit Switch

The Amana-Goodman 10123535 Limit Switch is a critical safety component designed for precise thermal regulation in residential gas furnaces and HVAC systems. As a genuine OEM replacement part, this 150 degree manual reset limit switch is engineered to interrupt the burner circuit when internal temperatures exceed its 150°F calibrated threshold, preventing heat exchanger damage and ensuring equipment longevity. This L150F M/R limit switch features a robust flush-mount design and a high-reliability bimetal disc for consistent performance in high-cycle environments. Unlike automatic reset switches, this manual reset furnace limit requires a technician's inspection before system restoration, providing an essential diagnostic checkpoint for airflow restrictions or cracked heat exchangers. This switch is a direct drop-in for numerous Amana, Goodman, and Janitrol furnaces, maintaining the exact factory specifications required for ETL and UL compliance. When replacing a furnace high limit switch, prioritize OEM integrity to ensure the precise trip point and terminal orientation match your specific cabinet configuration.

• OEM Precision: Guaranteed compatibility with Amana-Goodman 10123535 specifications for seamless field replacement.
• Thermal Protection: Calibrated 150 degree trip temperature prevents dangerous overheating conditions within the furnace cabinet.
• Manual Reset Safety: Forces an inspection of the unit after a high-limit event to address underlying mechanical or airflow failures.
• Durable Construction: Built with high-grade materials to withstand the thermal stresses of modern high-efficiency HVAC equipment.
• Broad Compatibility: Fits a wide range of Amana, Goodman, Janitrol, and Daikin gas-fired systems.

What causes a 150F manual reset limit switch to trip?
A trip is typically caused by insufficient airflow, often due to a dirty air filter, blocked return ducts, a failing blower motor, or a compromised heat exchanger.

Can I replace a manual reset switch with an automatic reset version?
No. In technical applications, you must match the exact OEM reset type and temperature rating (L150F) to ensure the safety circuit operates as designed by the manufacturer.

How do I test the 10123535 limit switch?
Using a multimeter, check for continuity across the terminals. If the switch is tripped, press the red button to reset; if continuity does not return, the internal bimetal disc is likely defective.
