The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the WFD18045S3AXCC furnace and compatible Goodman/Amana models. This high-limit switch monitors temperature in the heat-exchanger or burner area and opens the circuit to shut down the furnace if it overheats — protecting against dangerous conditions caused by restricted airflow, a failed blower, or flame rollout. Because it is a manual reset device, it stays tripped until an operator presses the button, prompting a technician to find and correct the root cause.

OEM vs. Generic

The genuine Goodman switch is calibrated to the exact trip temperature specified for this furnace, which is critical for a safety component. A generic switch with a different set point can nuisance-trip or, worse, fail to trip when it should. Always use OEM for limit and rollout controls.

Installation Difficulty

Intermediate. Requires disconnecting power, removing two mounting screws and the spade wire connectors, and installing the new switch in the same orientation. A licensed technician should also diagnose why the original switch tripped before returning the unit to service.

Restore safe furnace shutdown protection with the authentic Goodman 10123529 limit switch.
