This is a safety-critical high-limit\/overtemperature switch: it opens the control circuit and shuts down the furnace if it senses an abnormal temperature or flame rollout condition, protecting the heat exchanger and cabinet from overheating. Because it is a \u003cstrong\u003emanual reset\u003c\/strong\u003e device, it must be physically reset with the red button after a fault — and a switch that will not reset or that trips repeatedly signals an underlying airflow or venting problem that should be diagnosed.\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 safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens control circuit on overtemperature to shut down burners\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 WGGE4542A115MAA and cross-referenced models\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This switch is factory-set to the trip temperature specified for your furnace. Substituting a generic limit with a different set point defeats the engineered safety margin and can allow dangerous overheating or cause nuisance shutdowns. On a life-safety component, always use the OEM part with the correct trip rating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty: Easy (2\/5).\u003c\/strong\u003e About 15 minutes with a nut driver. Turn off power and gas, note wire lead positions, remove the two mounting screws, transfer the leads to the new switch, and remount. Restore power and cycle the furnace to confirm normal operation. If the new switch trips, do not bypass it — investigate blocked airflow, a dirty filter, or a venting fault.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSafety note:\u003c\/strong\u003e Never jumper or defeat a limit switch.
