Goodman 10123519 Manual Reset Rollout Limit Switch

The 10123519 is a genuine OEM manual reset rollout limit switch engineered for the Goodman GMH951155DXAC 95% AFUE two-stage gas furnace. This safety device monitors for dangerous flame rollout at the burner box and opens the ignition circuit if excessive heat is detected, shutting the furnace down to prevent damage and hazard. Because it is a manual reset device, it must be physically reset after a fault — a deliberate design that forces a technician to inspect the root cause before the unit restarts.

Specifications

Type: Manual reset rollout / flame-rollout limit switch
Function: Normally closed, opens on over-temperature
Fit: Goodman/Amana GMH951155DXAC and compatible 95% furnaces
Reset: Manual push-button
OEM Part Number: 10123519

OEM vs. Generic

The genuine Goodman OEM switch is calibrated to the exact trip temperature specified for this furnace platform, ensuring the safety circuit behaves as the manufacturer intended. Generic replacements may trip early (nuisance shutdowns) or late (reduced protection). For a safety-critical component, OEM is strongly recommended.

Installation Difficulty

Easy (1/5). Two spade terminals and one or two mounting screws. Always disconnect power before servicing. If the switch trips repeatedly after reset, have the heat exchanger and venting inspected by a licensed technician.
