Goodman 10123529 Manual Reset Limit Switch

Genuine OEM Goodman 10123529 is a manual-reset high-limit / rollout safety switch for the Amana-Goodman AMH80603AXBC gas furnace. This normally-closed thermal switch opens the control circuit and shuts down the burners if it senses an overheat or flame-rollout condition. Because it's a manual reset, it stays open until a technician presses the button — a deliberate safety design that forces the underlying fault to be investigated.

A tripped or failed limit switch will prevent the furnace from firing (no heat) or cause it to short-cycle on limit. Replacing a bad switch with the correct factory-spec part restores safe operation at the proper trip temperature.

OEM vs. Generic

OEM Goodman switches are calibrated to the exact trip temperature and mounting footprint your furnace was engineered for. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to protect the heat exchanger. For a safety-critical control, always use OEM.

Installation Difficulty

Easy (1/5). Cut power, note and transfer the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. A quick job for a tech; DIYers should always diagnose why the switch tripped before resetting.
