Goodman 10123538 Manual Reset Limit Switch

The Goodman 10123538 is a genuine OEM manual-reset high-limit switch engineered for the AMSS960402BNAA gas furnace and other compatible Goodman and Amana models. This safety control monitors heat-exchanger and burner-compartment temperature; if the furnace overheats due to a blocked flue, dirty filter, or failed blower, the switch opens the circuit and shuts down the burners to prevent a hazardous condition. Because it is a manual-reset design, it will not automatically restore power — a technician must physically press the reset button after clearing the underlying fault, giving you a clear signal that the unit tripped on a real overheat event.

Specifications

Type: Manual reset high-limit / rollout safety switch
Function: Opens on over-temperature to de-energize gas valve
Fits: Goodman / Amana AMSS960402BNAA and cross-compatible furnaces
Reset: Manual push-button
OEM Part Number: 10123538
Equipment: Gas Furnace

OEM vs. Generic

Choosing the OEM 10123538 guarantees the exact trip temperature, mounting footprint, and terminal spacing your furnace was certified for. Generic aftermarket switches often carry a different set-point or bracket, which can cause nuisance tripping or fail to protect the heat exchanger. For a life-safety component, we strongly recommend genuine OEM.

Installation Difficulty

Easy (1/5). Turn off power and gas, remove the two mounting screws, transfer the spade connectors, and reinstall. Most homeowners complete the swap in 10–15 minutes. If the switch trips again after reset, have a qualified HVAC technician diagnose the root cause before continued operation.
