The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM thermal safety control for the Amana/Goodman AMH81005CNBA gas furnace. Unlike auto-reset limits, this switch requires a manual button press to restore the circuit after a trip — an intentional design that forces inspection following an overheat or flame-rollout event before the furnace can operate again.

Specifications

Part type: Manual-reset high-limit / rollout switch
Reset: Manual push-button
Function: Opens the control circuit on overheat or flame rollout
Fits: Amana/Goodman AMH81005CNBA gas furnace
Terminals: Quick-connect spade
Brand: Genuine Goodman OEM

OEM vs. Generic

As a manual-reset safety device, the correct trip temperature is essential. The OEM 10123529 is factory-calibrated to your furnace's specification. Substituting a generic switch with a different set point risks nuisance lockouts or, more seriously, a failure to protect against genuine rollout conditions. Always use the genuine part for safety components.

Installation Difficulty

Easy (2/5). Disconnect power, remove the two mounting screws, transfer the spade wires, and mount the new switch. Budget 10–15 minutes. If the original switch had tripped, diagnose and correct the underlying cause (blocked flue, failed inducer, or dirty burners) before returning the furnace to service.
