🧩 Function & Application

This fan switch controls blower operation based on heat exchanger temperature. When the furnace heats up to 145°F, the switch closes to start the blower. As the furnace cools to 130°F, it opens to shut the blower off.

A failing fan switch can cause:

• Blower running too long

• Blower not starting

• Short‑cycling

• Overheating or poor airflow

Replacing it with the correct OEM part restores proper furnace timing and airflow.
