Goodman 10123519 Manual Reset Rollout Limit Switch

Restore reliable safety operation to your Goodman GKS91155DXAB gas furnace with this genuine OEM 10123519 manual reset rollout limit switch. This normally-closed thermal safety control monitors the burner compartment for flame rollout conditions and interrupts the gas valve circuit if excessive heat is detected outside the heat exchanger, protecting your equipment and home from unsafe combustion. Because it is a manual reset device, a tripped switch signals a genuine fault (blocked flue, cracked heat exchanger, or restricted airflow) that should be diagnosed before pressing the button to resume operation.

Specifications

Type: Manual reset rollout limit switch (SPST, normally closed)
Function: Flame rollout / high-limit safety cutout
Reset: Manual push-button
Mounting: Direct OEM bracket fit
Fits: Goodman GKS91155DXAB and compatible 90%+ gas furnaces

OEM vs. Generic

Our genuine OEM switch is calibrated to the factory trip temperature, guaranteeing correct nuisance-free operation and full compatibility with the GKS91155DXAB control sequence. Aftermarket generics may use looser calibration tolerances that trip early or fail to protect at spec — with a safety control, exact factory calibration matters.

Installation Difficulty

Easy (2/5) — Two-wire spade connection and a single mounting screw. Always shut off power and gas before servicing. Diagnose the underlying cause of any rollout trip before reset. Professional installation recommended if you are unsure of the fault.
