The Goodman 10123537 Manual Reset Limit Switch (Gray) is a genuine OEM high-limit safety control for the Goodman/Amana AMV90905DXAB gas furnace. This normally-closed switch monitors heat-exchanger and blower-compartment temperature and opens the circuit to shut off the burners if the furnace overheats — protecting against restricted airflow, dirty filters, or blower failure. Unlike an auto-reset control, it must be manually reset after a trip, prompting the homeowner or technician to investigate the root cause.

OEM vs. Generic

The OEM 10123537 is calibrated to the exact trip temperature specified for the AMV90905DXAB, ensuring the furnace shuts down at the safe threshold. A generic limit switch with a different setpoint or mounting footprint can nuisance-trip, fail to protect the heat exchanger, or fit poorly. For a critical safety component, the factory-matched part is strongly recommended.

Install Difficulty

Moderate (2/5). Requires disconnecting two wire terminals and removing two mounting screws, plus correct orientation against the mounting surface. Basic hand tools and a multimeter for continuity testing are helpful. Always shut off power and gas before replacing safety controls.
