The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the GMH951155DXAF gas furnace and compatible Goodman/Amana equipment. This normally-closed switch opens and cuts power to the burners if the heat exchanger or plenum exceeds its safe temperature threshold — protecting against overheating from restricted airflow, a failed blower, or a dirty filter. Because it is a manual reset device, it must be physically reset after a trip, alerting the homeowner or technician that a fault occurred.

  • Part Type: Manual reset high-limit switch
  • OEM Part #: 10123519
  • Fits: Goodman GMH951155DXAF and related furnace models
  • Function: Overheat / rollout safety cutoff
  • Reset: Manual push-button reset
  • Brand Compatibility: Goodman & Amana

OEM vs. Generic: The OEM 10123519 is calibrated to the exact trip temperature and mounting footprint specified for this furnace. Generic limit switches with the wrong temperature rating or terminal orientation can trip prematurely or fail to protect the heat exchanger. This is a safety-critical component — OEM is strongly recommended.

Install Difficulty: Easy (2/5). Two mounting screws and two spade terminals. Verify the correct trip temperature is stamped on the disc and de-energize the furnace before replacing.
