Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset high-limit switch built for the WGFM28070V4BXAA gas furnace. This safety control monitors heat-exchanger and cabinet temperature and opens the circuit if the furnace overheats, shutting down the burners to prevent damage or fire. Because it is a manual reset design, it must be physically reset after a trip — a repeated trip indicates an airflow or overfiring problem that should be diagnosed before returning the unit to service.

OEM vs. Generic

The OEM Goodman 10123529 is calibrated to the furnace's exact trip temperature and mounting footprint, so it protects the equipment at the manufacturer-specified setpoint. Generic limit switches may carry the wrong temperature rating or terminal orientation, which can cause nuisance trips or, worse, fail to protect the furnace. For a safety component, always use the genuine OEM switch.

Installation Difficulty: Easy

Rated Easy (2/5). Shut off power and gas, note wire positions, unscrew the failed switch, install the 10123529 in the same orientation, reconnect the leads, and confirm proper operation. Diagnose any underlying overheating cause before relying on the new switch.
