Mounted in or near the blower compartment, this secondary safety limit guards against heat buildup in areas the primary high-limit does not cover, such as when a blower fails or airflow is restricted.

The OEM 0130F00038 (light blue) guarantees you install the exact set point and mounting the furnace was designed for. Substituting a differently-rated snap disc — even one that looks similar — can defeat the intended protection or cause nuisance shutdowns.
