This manual-reset switch opens the ignition circuit if the furnace overheats or a rollout condition occurs, then stays open until pressed — protecting the heat exchanger and household from unsafe operation. If your furnace locks out on high limit or won't restart after an overheat event, this is the part to replace.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 10123529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman DMP125-52AA gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM 10123529 is calibrated to the exact trip temperature the DMP125-52AA safety design requires. A generic switch with the wrong setpoint can nuisance-trip or, worse, fail to protect the heat exchanger.
