The Goodman 10123533 is a genuine OEM manual-reset high-limit / rollout safety switch designed for the GMH951155DXAG 95% AFUE gas furnace and compatible GMH95 series units. This normally-closed thermal safety switch interrupts the ignition circuit when it detects an over-temperature condition — such as flame rollout, a cracked or blocked heat exchanger, or restricted airflow — and requires a manual push-button reset after the underlying fault is corrected. It is an essential protection against overheating and combustion escape.
Each limit switch trips at a factory-specified temperature. The OEM 10123533 ensures the exact setpoint, terminals, and mounting your furnace expects. A mismatched generic switch can cause false lockouts or fail to protect against a real overheat — unacceptable for a safety component. Choose the exact-fit OEM part.
Easy — Two spade connectors and simple bracket mounting. Cut power, swap the switch, and reset. Straightforward for DIYers — but always identify and fix the cause of any trip before restoring furnace operation.
