Description
The York S1-02526392005 Control Switch Rollout 225F Open / 145F Close is a safety control used in gas furnace combustion chambers to monitor excessive heat conditions near the burner area. It is positioned in the rollout zone where flame or hot gases may escape under abnormal operation. When temperature reach the upper threshold, the switch opens to interrupt the control circuit, stopping burner operation until conditions return to normal. This component is commonly used in residential and light commercial HVAC heating systems and it supports burner safety control, protects surrounding components and assists controlled shutdown during unsafe heat exposure.
