The Goodman 10123519 is a genuine OEM manual reset high-limit switch built as a direct-fit replacement for the WGFM195115S5DAC gas furnace. This safety control opens the ignition circuit if it senses excessive heat — such as from a blocked flue, dirty filter, or failed blower — and requires a manual reset button press to restore operation, protecting the heat exchanger and cabinet from overheating.

Specifications

Type: Manual reset high-limit / rollout safety switch
Function: Opens on overtemperature, normally closed
Reset: Manual push-button
Fits: WGFM195115S5DAC and compatible Goodman/Amana furnaces
Part Number: 10123519

OEM vs. Generic

Limit switches trip at a precise temperature calibrated to the furnace design. A generic switch with the wrong trip point may nuisance-trip or, worse, fail to protect the unit. This OEM Goodman limit switch is factory-calibrated to the exact temperature and terminal layout your furnace requires for safe, reliable cycling.

Installation Difficulty

Easy (2/5). Shut off power and gas, unplug the wiring terminals, remove the mounting screws, and install the replacement in the same orientation. Press the reset button and test-fire the furnace. If the new switch trips, investigate airflow or venting before further operation.
