The Goodman 10123529 is a genuine OEM manual reset limit (flame roll-out) switch for the AMH80403AXBD gas furnace and related Goodman/Amana models. This safety control is mounted at the burner box and opens the gas-valve circuit if it senses abnormal heat from flame roll-out, shutting the furnace down to prevent damage or a hazard. Because it is manual reset, a tripped switch must be pressed to restore operation — and the underlying cause (blocked flue, cracked heat exchanger, dirty burners) should be investigated.

Part number: 10123529
Type: Manual reset roll-out limit switch
Function: Opens gas circuit on abnormal heat / flame roll-out
Terminals: Dual 1/4" spade quick-connect
Fits: AMH80403AXBD and compatible Goodman/Amana furnaces

OEM vs. Generic

As a listed safety device, the OEM switch is calibrated to the exact trip temperature the furnace design requires. Generic switches may carry a different set point or reset behavior, which can either allow unsafe operation or cause nuisance trips. We strongly recommend the genuine OEM part for any combustion safety control.

Installation Difficulty

Easy (1/5). Power down the furnace, unplug the two spade terminals, remove one or two mounting screws, and install the replacement in the same orientation. About 10–15 minutes. If the switch keeps tripping after replacement, stop and have a technician inspect the heat exchanger and venting.
