Carrier 338096-702 Limit Switch Assembly

The Carrier 338096-702 is a limit switch assembly, a safety control that monitors temperature inside a furnace or other heating equipment and shuts off the heat source if the temperature at the switch exceeds its set point. The switch opens the control circuit on excess temperature and resets once the equipment has cooled to a safe level.

A limit switch that trips repeatedly usually points to restricted airflow from a dirty filter, a failed blower or blocked ductwork, so correct the airflow problem when replacing the switch. This is a genuine Carrier replacement part; confirm the part number on the existing assembly before ordering.
