The Goodman 10123533 is a genuine OEM manual-reset high-limit switch for the GKS90905DXAB gas furnace. This safety control monitors temperature at the heat exchanger and opens the circuit to shut down the burners if the furnace overheats — protecting against cracked heat exchangers, restricted airflow, and fire hazards. Because it is a manual-reset design, it must be physically reset after a trip, alerting the homeowner or technician that an overheat condition occurred and needs diagnosis.

  • OEM Part Number: 10123533
  • Type: Manual reset high-limit safety switch
  • Reset: Manual (press-to-reset button)
  • Fits Model: GKS90905DXAB (Goodman gas furnace)
  • Function: Opens burner circuit on over-temperature

OEM vs. Generic: The genuine Goodman 10123533 is calibrated to the exact trip and reset temperature specified for the GKS90905DXAB, with the correct mounting flange and terminal layout. Generic limit switches with the wrong trip point can nuisance-trip or, worse, fail to protect the heat exchanger.

Install Difficulty: Moderate (2/5). Disconnect power, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. Verify correct trip temperature rating before installing. Always shut off power and gas first.
