The Goodman 10123529 manual reset limit switch is a genuine OEM safety control for the AMH80905CXCB gas furnace and compatible Goodman/Amana models. This normally-closed switch opens to shut off the burners if it senses excessive temperature — protecting against overheating and flame rollout. Because it is a manual reset device, it must be physically reset with the button after a trip, alerting the homeowner that a fault (blocked airflow, dirty filter, or failed blower) needs attention.

OEM vs. Generic

The OEM 10123529 is calibrated to the exact trip temperature specified for your furnace, ensuring the safety circuit behaves as engineered. Generic equivalents may carry a different set-point tolerance; for a safety-critical control we strongly recommend the OEM part to preserve proper protection and manufacturer warranty coverage.

Installation Difficulty

Easy. Turn off power and gas, disconnect the two spade terminals, unscrew the switch from its mounting bracket, and install the replacement in the same orientation. About 15–20 minutes. If the switch trips again immediately after replacement, diagnose the underlying airflow or combustion problem before re-running the furnace.
