Genuine Goodman 10123539 Manual Reset Limit Switch

The Goodman 10123539 is an OEM manual-reset high-limit safety switch for the Goodman/Amana AMEC960402BNAB gas furnace. This critical safety device monitors heat-exchanger temperature and cuts power to the burners if the furnace overheats — protecting against fire and equipment damage. Because it is a manual-reset design, it stays open after a trip until an operator presses the reset button, prompting inspection of the underlying cause (such as a blocked filter or failed blower).

Specifications

Part Number: 10123539
Type: Manual reset high-limit / rollout safety switch
Function: Opens on over-temperature to shut off the burners
Reset: Manual push-button
Compatibility: Goodman/Amana AMEC960402BNAB furnace

OEM vs. Generic

As a genuine OEM Goodman safety component, the 10123539 is calibrated to the exact trip temperature your furnace requires. Safety switches are not the place to compromise — a generic switch with the wrong setpoint can trip nuisance faults or, worse, fail to protect the unit. OEM guarantees correct calibration, mounting, and warranty compliance.

Installation Difficulty

Moderate (2–3/5). Replacement involves removing two mounting screws and transferring the wire leads. Always shut off power and gas before servicing. Because this is a safety control, have a qualified HVAC technician diagnose and confirm the repair if you are unsure.

Order the authentic Goodman 10123539 today to restore your furnace's essential over-temperature protection.
