The Goodman/Amana 10123539 Manual Reset Rollout Limit Switch is a genuine OEM safety control designed for AMEC960402BNAC gas furnaces and compatible Goodman and Amana equipment. This normally-closed thermal switch monitors the burner box for flame rollout conditions and interrupts the gas valve circuit if excessive heat is detected, protecting your furnace and home from a dangerous overheat event.

Because this is a manual reset device, a tripped switch signals a real problem — such as a blocked heat exchanger, restricted venting, or improper combustion — that should be diagnosed before pressing the reset button. Installing the correct OEM-spec part ensures the switch trips at the factory-calibrated temperature.

  • Type: Manual reset rollout / flame limit switch
  • Contacts: Normally closed (SPST), opens on rise
  • Function: Flame rollout / high-temperature safety cutout
  • Fits: Amana AMEC960402BNAC and select Goodman/Amana gas furnaces
  • OEM Part #: 10123539

OEM vs. Generic: Our genuine OEM 10123539 is calibrated to the exact trip temperature the furnace was engineered around. Generic universal switches may carry a different set point or mounting bracket, risking nuisance trips or, worse, a delayed safety cutout. For a safety-critical component, OEM is strongly recommended.

Install Difficulty: Easy (⭐⭐☆☆☆). Two-wire spade connection and a single mounting screw. Always shut off power and gas before servicing. If the original switch tripped, have a qualified technician confirm the root cause before restoring operation.
