The OEM Goodman 10123529 manual reset limit switch is a genuine high-temperature safety control for the Amana/Goodman AMH80803BNBC gas furnace. This normally-closed switch opens and cuts power to the gas valve if it senses an overheat or flame-rollout condition, then requires a manual button press to reset — a deliberate design that forces a technician to investigate the root cause before the furnace can fire again.

Specifications

Type: manual reset high-limit / rollout switch
Configuration: normally closed, opens on over-temperature
Function: shuts off gas valve on overheat or flame rollout
Fits: Amana & Goodman AMH80803BNBC furnaces
OEM Part Number: 10123529

OEM vs. Generic

This is a safety component, and its trip temperature is calibrated to the furnace's specific heat-exchanger and burner design. The OEM 10123529 trips at the exact factory set point. Generic or mismatched-temperature switches may nuisance-trip or, worse, fail to open when they should. For a listed safety device, always install the genuine OEM part.

Install Difficulty: Easy

About 15 minutes. Cut power at the disconnect, note or photograph the wiring, remove the two mounting screws, and transfer the spade connectors to the new switch. Mount it in the same location and orientation, restore power, and run a full heat cycle to confirm normal operation. If a rollout switch tripped, diagnose the cause before returning the unit to service.
