The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM safety control for the GMH951155DXAE 96% AFUE two-stage gas furnace and compatible Goodman/Amana high-efficiency models. This normally-closed high-limit switch monitors heat-exchanger and burner-area temperature; on an overheat or flame-rollout event it opens to cut power to the gas valve, then requires a manual button press to reset — a deliberate safeguard against repeat unsafe cycling.

Specifications

Part Number: 10123519
Type: Manual reset high-limit / rollout switch
Contacts: Normally closed, opens on overtemperature
Fits Model: GMH951155DXAE (and compatible Goodman 96% AFUE furnaces)
Function: Overheat / flame-rollout safety cutout

OEM vs. Generic

This factory OEM switch is calibrated to the precise trip temperature Goodman specifies for the GMH95 heat exchanger, with the correct mounting bracket and terminal spacing. Generic limit switches with the wrong setpoint can nuisance-trip during normal operation or, worse, fail to trip when needed. For a life-safety control, matching the OEM specification is essential.

Installation

Difficulty: Easy (2/5). Turn off gas and power, disconnect the two spade terminals, remove the mounting screws, install the new switch in the same orientation, and reconnect. About 20 minutes. If the switch had tripped, diagnose the root cause (blocked flue, dirty filter, failed blower) before returning to service.

Protect your furnace and home with the exact factory safety switch Goodman designed for this model.
