The Goodman 10123529 is a genuine OEM manual-reset limit (rollout) switch for the Goodman/Amana AMH80904BXCB gas furnace. This safety control opens and cuts gas/ignition if it senses abnormal high heat or flame rollout at the burner box, protecting the furnace and home from overheating. Because it is a manual-reset device, a tripped switch must be physically reset with the red button after the underlying cause (blocked flue, dirty heat exchanger, weak inducer) is corrected.

Specifications

Type: manual reset high-limit / flame rollout switch
Function: opens control circuit on overtemperature
Reset: manual push-button
Fit: Goodman & Amana 80% AFUE gas furnaces (AMH80904BXCB)
OEM part number: 10123529

OEM vs. Generic

The genuine Goodman 10123529 is calibrated to the exact trip temperature the furnace was safety-listed for. Substituting a switch with a different set point can allow dangerous overheating or cause nuisance lockouts. For a listed safety control, always use the OEM part.

Install Difficulty

Moderate (2/5). Turn off power and gas, disconnect the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. Simple mechanically, but diagnose why the original tripped before returning the furnace to service.

Confirm your model and serial before ordering.
