The Goodman 10123539 Manual Reset Limit Switch is a genuine OEM high-temperature safety cutout for Goodman and Amana AMSS960804CNAA gas furnaces. It monitors for overheating or flame rollout conditions and opens the control circuit to shut down the burners when temperature exceeds its factory setpoint. Because it is a manual reset device, it stays open after a trip and must be reset by hand — a deliberate design that forces a technician to inspect the furnace before it can fire again, rather than silently cycling on a dangerous fault.

Specifications

Part type: Manual reset limit / rollout safety switch
Reset: Manual (push-button)
Action: Normally closed, opens on overtemperature
OEM part number: 10123539
Fits: Goodman/Amana AMSS960804CNAA and compatible 96% AFUE furnaces

OEM vs. Generic

This is a life-safety component. Aftermarket switches with a mismatched trip temperature or slower response can either nuisance-trip in normal operation or, worse, fail to open during a genuine rollout event. The genuine 10123539 is calibrated to Goodman's exact furnace specification, so it protects as engineered. On safety controls, we always recommend true OEM.

Install Difficulty

Easy (2/5) — Disconnect power at the furnace, unplug the two spade terminals, remove the mounting screws, install the new switch in the same orientation, and reconnect. If the original tripped, diagnose and correct the root cause (blocked flue, cracked heat exchanger, restricted airflow) before returning the unit to service.

In stock and ready to ship. OEM fit guaranteed.
