Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a manual reset high-limit switch engineered as a critical safety component for the ADSH800804BXAA furnace and compatible Goodman/Amana gas furnace platforms. When the heat exchanger area exceeds its safe operating temperature — typically from a blower failure, dirty filter, or restricted airflow — this switch opens the circuit to shut down the burner and prevent overheating damage. Because it is a manual reset device, it requires a physical press of the reset button after a trip, alerting the homeowner or technician that an underlying airflow issue needs attention.
