This manual-reset thermal switch protects against flame rollout and dangerous overheating in the burner or heat-exchanger area, cutting power to the gas valve when an unsafe temperature is detected.\u003c\/p\u003e\u003cp\u003eBecause it is a \u003cstrong\u003emanual reset\u003c\/strong\u003e device, once it trips it must be physically reset by pressing the button — it will not auto-recover. Frequent tripping usually points to a blocked flue, dirty burners, or a cracked heat exchanger, so inspect the system when replacing this switch. A failed or worn switch may trip on normal cycles or fail to reset, leaving the furnace with no heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 10123539\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset limit \/ flame rollout switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e High-temperature safety cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e VMSS960804CNAA (and related Goodman furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The genuine Goodman switch is calibrated to the furnace's exact trip temperature and mounting footprint — critical for a safety device.
