The Goodman 10123518 is an OEM manual reset limit switch for the WGFM295045V3BAA gas furnace. This normally-closed thermal safety trips on excessive temperature — typically flame rollout or overheat conditions — and stays open until manually reset, forcing a technician to inspect the furnace before it can run again.

Specifications

Type: Manual reset high-limit / rollout switch
Action: Normally closed, opens on over-temperature, manual reset button
Function: Locks out the burner after an overheat/rollout event
Fits: Goodman/Amana WGFM295045V3BAA furnace
Safety class: Critical combustion safety control

OEM vs. Generic

The OEM Goodman switch carries the exact trip temperature and terminal layout the WGFM series requires. Because a manual reset limit is a last-line safety device, an incorrect setpoint from a generic part can allow unsafe operation or cause repeated lockouts. OEM is strongly recommended for safety-critical controls.

Installation Difficulty

Easy (2/5). Disconnect furnace power, unplug the terminals, remove the mounting screws, and install the new switch. About 10–15 minutes. Important: a repeatedly tripping limit signals an underlying problem (blocked flue, dirty heat exchanger, restricted airflow) — diagnose the root cause, don't just reset.
