Goodman 10123519 Manual Reset Rollout Limit Switch

The Goodman 10123519 is a genuine OEM manual reset flame-rollout limit switch engineered for the GKS91155DXAG gas furnace and compatible Goodman/Amana models. This safety control monitors for flame rollout at the burner box and interrupts the ignition circuit if abnormal heat is detected, protecting the heat exchanger, cabinet, and your home. Because it is a manual reset device, it will not automatically re-close after tripping — a service technician must inspect the cause and press the reset button, ensuring a persistent fault is never silently ignored.

Specifications

Type: Manual reset flame-rollout limit switch
Function: Normally-closed high-limit safety cutout
Mounting: Bracket / burner-box mount (direct OEM fit)
Terminals: 1/4 in. quick-connect spade
Fits: Goodman/Amana GKS91155DXAG and compatible GKS9 series furnaces
Brand: Genuine Goodman OEM

OEM vs. Generic

Our genuine Goodman OEM 10123519 is calibrated to the exact factory trip temperature for this furnace platform. Aftermarket "universal" rollout switches often use approximate set points that can cause nuisance trips or, worse, fail to protect at the correct threshold. For a safety-critical control, the OEM part is the recommended choice.

Install Difficulty

Easy (2/5). Replacement typically takes 10–15 minutes: shut off power and gas, photograph the wiring, unplug the two spade terminals, unscrew the switch, and reverse the process with the new part. Always confirm the fault condition is resolved before restoring service.

Compatibility note: Verify your furnace model and the original part number before ordering. Fits Goodman GKS91155DXAG.
