Goodman 10123529 Manual Reset Limit Switch

The genuine OEM Goodman 10123529 is a manual-reset limit (flame rollout) switch for the Goodman/Amana AMH80603ANBB gas furnace. This normally-closed safety control opens and cuts power to the gas valve when it senses abnormal heat — typically flame rollout at the burner box caused by a blocked heat exchanger, poor venting, or a failing inducer. Because it is manual-reset, it will not auto-restart: it stays open until the button is pressed, forcing a service inspection. If your furnace locks out on a rollout fault, the underlying cause must be corrected before resetting or replacing this switch.

  • Type: manual-reset rollout / flame limit switch
  • Contacts: normally closed, opens on over-temperature
  • Function: cuts gas valve power on flame rollout
  • Fits: Goodman & Amana AMH80603ANBB furnaces
  • OEM part number: 10123529

OEM vs. Generic: The trip temperature and reset threshold are matched to this furnace's burner-box design. The genuine Goodman 10123529 trips at the factory-specified setpoint for reliable protection. Generic switches with a different rating can nuisance-trip or fail to protect — this is a life-safety component, so the OEM part is strongly recommended.

Install difficulty: Easy (2 of 5). Power off, unplug the two spade terminals, unscrew the switch from the burner bracket, and mount the replacement. Basic hand tools only. IMPORTANT: diagnose and fix the rollout cause first.
