The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit / flame-rollout safety control for AMH81005CXBD gas furnaces and compatible Goodman/Amana models. This switch monitors for abnormal heat or flame rollout at the burner box and cuts power to the gas valve if a dangerous temperature is reached. Because it is a manual reset device, it will not re-close on its own — a tripped switch signals a real fault (blocked flue, dirty burners) that should be diagnosed before resetting.

Specifications

Type: Manual reset thermal limit / rollout switch
Function: High-limit combustion safety cutout
Reset: Manual push-button
Mounting: OEM bracket-mount, spade terminals
Fits: AMH81005CXBD and related Goodman/Amana 80% furnaces

OEM vs. Generic

OEM 10123529 is calibrated to the exact trip temperature specified for this furnace's burner enclosure. Generic switches with the wrong set point either nuisance-trip in cold weather or fail to protect against genuine rollout. As a life-safety component, always use the OEM-rated switch.

Install Difficulty

Easy — Shut off gas and power, unplug the two spade connectors, remove the mounting screws, and swap in the new switch. Takes about 10–15 minutes. If the switch trips again after reset, do not bypass it — call a technician.
