The Goodman 10123529 manual reset limit switch is a genuine OEM safety control for the WGFM28090V5CXAA gas furnace and related Goodman/Amana models. This normally-closed thermal switch opens and shuts off the gas valve if it senses an overheat or flame-rollout condition, then requires a manual reset button press to restore operation — an intentional safeguard that forces a technician to inspect the cause before the furnace runs again.

Specifications

Type: Manual reset thermal limit / rollout switch
Contacts: Normally closed (opens on temperature rise)
Function: High-limit / flame-rollout overheat protection
Reset: Manual push-button
Fits: Goodman WGFM28090V5CXAA and related V-series furnaces
OEM Part Number: 10123529

OEM vs. Generic

Safety limit switches are calibrated to a specific trip temperature. The OEM 10123529 is factory-set to the exact threshold Goodman engineered for this heat exchanger, so it trips neither too early (nuisance lockouts) nor too late (a real safety risk). Generic switches with approximate temperature ratings can compromise this protection. For a life-safety component, OEM is strongly recommended.

Installation Difficulty: Easy

Rated Easy. Disconnect power, note wire positions, unscrew the switch from its bracket, transfer the two spade terminals, and mount the new switch. If a manual reset switch has tripped, always diagnose the root cause — blocked flue, cracked heat exchanger, or failed blower — before returning the furnace to service. Work should be done by a licensed HVAC professional.
