The Goodman 10123529 is a genuine OEM manual reset limit (rollout) switch for AMS80603AXAD gas furnaces. This normally-closed thermal safety opens the ignition circuit if it detects flame rollout or excessive burner-area heat, shutting the furnace down to prevent damage and hazardous operation. A tripped or failed switch is a common cause of a furnace that lights briefly then locks out.

Part number: 10123529
Type: Manual reset rollout / limit safety switch
Fits: Goodman/Amana AMS80603AXAD 80% AFUE furnaces
Action: Normally closed, opens on overtemp; manual reset button
Compatibility: OEM direct replacement

OEM vs. Generic

The OEM 10123529 is factory-calibrated to the furnace's exact trip temperature and bracket footprint. A generic switch with a different setpoint can nuisance-trip or, worse, fail to trip when it should. Because this is a safety device, we strongly recommend the genuine OEM part.

Installation Difficulty

Easy (2/5). Two spade terminals and one or two mounting screws. Shut off power first. Important: a repeatedly tripping rollout switch signals a real combustion problem — diagnose the root cause (blocked flue, cracked heat exchanger, dirty burners) rather than only replacing the switch.
